In addition, the area should be free from obstruction to allow for large trailers to access to the site and for a crane to lift the module and place it on its support pad. Consideration should be given to obstructions such as adjacent buildings, trees, lamp posts, low and high voltage wires, etc., The module must not be located within 200m of the sea. For marine applications, contact Schneider Electric for additional details. Note : Insure that considerations are made in regards to the proximity and access to utility and/or generator power, drainage, network connections, water or chilled water, if applicable.

2.9 Pad or Mounting Design When planning to install your module on a concrete pad or pedestal supports (See Figure 5 and 6, respectively), in addition to adhering to the above specifications discussed in this document, it is advisable to work with a qualified general contractor and civil engineering firm to ensure proper design and construction of your mounting pad. As mentioned above, consideration should be given to location, extreme weather conditions, proximity to site resources, delivery, installation of the module or multiple modules, access to modules by personnel and equipment, and clearance around air conditioners and vents. Place module in a location that allows for water to drain away from the module (See Figure 7). Insure that your pad has the means to anchor the module and complies with local seismic requirements. The pad design must be able to support the weight of a fully loaded module. Accessibility of staff and contractors should also be considered and may include the need for steps or ramps to meet local and national codes. In addition to anchoring, the pad can also be used to run the cables under the product. Figure 7 shows where the electrical conduit and networking cables should emerge from the pad. Local regulations should be followed when designing the conduit in the pad.

2.10 Disclaimer The weights included in this manual are estimated and might not be completely accurate. They must be verified by the fabricator after the unit has been fully assembled.



3. Site Requirements – Conditions

3.1 Zoning Regulations and Permitting Consideration s Prior to the installation of the module, it is important to determine any applicable specific zoning regulations or permitting requirements. Engaging with the Authority Having Jurisdiction (AHJ) early on in the site planning process along with the property owner, if applicable, will allow for a trouble-free installation of the module. It is the customer’s responsibility to determine, comprehend and adhere to all local and national code and regulations as they pertain to their specific site, the installation of the module, and the electrical power connections.

3.2 Wind Loading Capacity The product can be used in a wide range of locations according to the following maximum condition Wind: Very High. Maximum basic Speed of 68m/s (150mph) The foundation loads included in this report correspond to the critical combination of actions for the largest wind demand.

• The air flow taken in by the fans via the condenser coil must not be obstructed in order not to reduce the efficiency of the unit and to avoid the unit stopping because of the intervention of the compressor’s safety functions;

• If the installation location is windy, it is advised to choose a protected area since the condensate axial fans have limited pressure (not greater than 10Pa).

Figure 8- Providing correct spacing to avoid insuff icient air flow

3.3 Weight Bearing Requirements The product must be installed on a surface (pads, ground/floor/roof slab) capable of supporting the combined weight of the unit and the delivery vehicle. Place the product on a site capable of bearing the weight of the unit and resisting ground shifting due to weather conditions. Place the product in a location that is not readily accessed by the general public.



3.4 Uplift/Lateral Capacity of Foundation Due to high wind loads and seismic demand, the unit must be anchored down to the base at the indicated positions using adequate brackets or fixings. See section four for additional details on anchorage

3.5 Surface Requirements The product can be installed on adequately designed concrete pad or pads suitable for its dimensions, weight and base loads, or the finished floor of a building. Before installing, ensure the stability of the surface or the structure where the unit will be placed is maintained. Take care to make sure these adequate conditions remain constant over the expected lifetime of the module installation. All the bases must have adequate vertical support, and all ISO-block bases must be fastened down to the foundation (support structure) by adequate brackets or fixings. The end user must ensure that the supporting ground conditions are adequate. Foundation design should be completed by a local contractor. See additional consideration around pad design in Section 6.0.

3.6 Water Drainage Requirements For external installations, care must be taken to place the product in a location that is graded to drain water away from the module. Ground pads/slabs should be raised up above the surrounding ground surface level to prevent water ingress (min 150mm).

3.7 Clearance Requirements Proper clearances must be observed for all of the travel routes to and on the customer property. If a crane is used to place the container, the greater of the clearances required by the crane or tractor trailer needs to be considered and the area above and around the crane must be free of obstructions: overhead power lines, etc.

3.7a Minimum Clearances Around Module: Description Recommended Distance External clearance around module 2500mm Clearance at point of egress/personal doors 1200mm Clearance around wall mount coolers 1500mm (Required for airflow)

See Figure 9 for diagram of interior layout. Check with local authority having jurisdiction (AHJ) to confirm clearance requirements for specific sites.

6. Additional Considerations 6.1 Severe Weather Conditions and Natural Disasters

� Earthquakes/Seismic Activity – In regions that are prone to earthquakes and seismic activity, customers should consult with a local AHJ and civil engineering firm to meet proper requirements and construction e.g. pad design and anchoring

� Flooding – Schneider Electric enclosures are designed to meet NEMA 4R / IP 56 standards. They are NOT designed to withstand standing water. When determining site location, please insure to select an area that is not prone to flooding. Consult with local flood plain maps or the equivalent.

� High Winds/ Tornados – In areas that are prone to high wind or tornado conditions, insure that the enclosure is properly anchored into the concrete to meet or exceed high wind/tornado requirements. In addition, insure the site around the enclosure is free from debris and material that could damage the enclosure in the event of a high wind incident.

� Hurricanes/Tsunamis - Consider the above recommendations in the event of possible flooding, high winds or a combination of both.

� Extreme High/Low Temperature Operations – Insure to consult with Schneider Electric early in the planning phases where the module will be temporarily exposed to extreme weather conditions. High temperature operations may require a temporary derating of the cooling system or an additional structure to mitigate direct sun light or blown sand which will require a vestibule. For extreme low temperatures, water, if applicable, may need to be treated or heated to prevent freezing or an additional internal heater added to maintain proper internal temperatures.

� Sand/Blown Dust & Debris – In environments such as deserts, customers need to consider during the planning phase how to address fine particulate such as sand. Vestibules are a common way to separate the critical environment from the outdoor elements. Main access doors should never be left open on modules as dust and other fine particulates can potentially cause problems with the operation of critical systems within the module.

6.2 Physical Threat and Security Depending upon your site location, additional security and physical threat measures may need to be taken into account to insure targeted availability of your solution. The networking switch provides the connections for monitoring (See Figure 15). Consider your location of your module in proximity to other mechanical devices, parking lots, access roads and paths, fuel storage and brush. Physical Security – Consider a barrier fence or piling to be erected to prevent easy and unrestricted access to the module and its connection points. Perimeter walls, fences, and security controlled gates should be considered as a passive means of restricting access. Heavier barriers should be considered to prevent accidental damage to modules from nearby vehicles. Allow for proper service clearances and required distances between modules and other equipment such as generators. Monitoring – The power module comes with internal cameras and an environmental monitoring system including dry contacts for door access. In



addition, customers may want to consider external cameras for surveillance of the site. The fire suppression system within the module can be tied into a local BMS to alert staff in the event of a thermal event. Audible and visual alarms are provided as part of the solution. Environmental Monitoring � Dry contacts for doors � Smoke detection with optional Vesda system � Water / leak detection on floor � Heat detection
