Precautions
Prepare a rainproof cloth to protect the Mini-shelter from rain before the installation is completed.
If the cabinet is scratched during transportation, paint or apply glue to the scratched areas.
If a Mini-shelter is assembled onsite, the site environment should be equal to or above 0°C (32°F). Otherwise, thetape cannot be attached firmly.
The following figure shows the required clearances around the Mini-shelter.
Ensure that cabinet doors do not face the nearest residential areas.
Installation and maintenance personnel must be trained to perform operations correctly and safely.

1. Remove the seal cover from the bottom.
2. Cut a hole in the seal cover along the lines using a
knife or a pair of scissors based on the cross-
sectional area of the cable.
3. Plug the cable hole using the processed seal cover.
The cable can be routed through the hole in the sealcover.
b
Principles for Laying Out Cables
Route cables inside the cabinet.
• Route cables along the cable shelves beside both sides
of the 19-inch rack and the cable try on the rack top.
• Cables in a bundle must be sorted and free from
crosses. Never bind cables at turnings.
• Signal cables and power cables must be bundled
separately, keep them at least 3cm from each other.
Route external cables into the cabinet through the
cable holes at the cabinet bottom.

9 From ground bolt at the department
bottom to the other ground bolt at theother department bottom
5 From BTS to indoor ground bar
The indoor ground bar should be installed near the surge protection device (SPD) on the AC input side. That is, if the ACDB has
level B surge protection, you need to install the indoor ground bar on the rack near the ACDB.

Check the power distribution cable and the cable label.
Verify that the output voltages of the ACDB, power system, and DCDU meet the following requirements:• AC voltage range: 200 –240 V
• DC voltage range: 38 –58 V
Verify that the DIP switch of the monitoring equipment is set properly.
Power on the Mini-shelter in the sequence as shown in the following figure.
Switch on the mains output circuit breaker
Switch on the ACDB input and load output circuit breakers.
Switch on the AC input circuit breaker on the power system.
Switch on the AC output circuit breakers (located on the power
system) that connect to the DCDU, storage batteries, temperature
control equipment, monitoring equipment, and BBU.
2 Setting the PMU Parameters of Power System
If the battery circuit breakers are switched to the ON position but the LCD on the PMU panel remains blank, flip the battery
switch to the BAT ON position. After 2 minutes, flip the battery switch to the Normal position to avoid battery overdischarge.
If the battery voltage remains low and the PMU is disconnected again after you flip the battery switch to the Normal position,
flip the battery switch to the BAT ON position for 2 minutes after the PMU connects to the mains.
