Emerson 115-208 Manuel D’Utilisation

1. While the Liebert

®

 APM

™

 and ancillary cabinets are still on the truck, inspect the equipment and 

shipping container for any signs of damage or mishandling. Do not attempt to install the system if 

damage is apparent. If any damage is noted, file a damage claim with the shipping agency 

immediately and contact Liebert Services at 1-800-LIEBERT to inform them of the damage claim 

and the condition of the equipment.

2. Compare the contents of the shipment with the bill of lading. Report any missing items to the 

carrier and your local Emerson representative immediately.

3. Check the product label on the back of front door and confirm the contents match the UPS model, 

capacity and main parameters that were ordered.

If the equipment will not be installed immediately, it must be stored indoors where the humidity is no 

higher than 90% and the temperature is no higher than 104°F (40°C). The storage area must protect 

the Liebert APM from excessive moisture (see 11.2 - UPS Environmental).

The equipment supplied has an identification tag on the back of the main door listing the type and 

size of the UPS.

Choose a location for the UPS that offers:

• Easy connection to inputs, outputs and auxiliary equipment
• Enough space to service the UPS
• Air circulation sufficient to expel heat produced by UPS
• Protection against moisture and excessive humidity
• Protection against dust and other particulate matter
• Compliance with fire prevention regulations and practices
• Operating environment temperature of 74-80°F (23-27°C) for maximum battery efficiency

If the UPS must remain disconnected from power for more than six (6) months, the batteries 

(if so equipped) must be recharged before use. To charge the batteries, the unit must be 

connected to utility power and started up—the charger operates only while the Liebert APM 

is operating.

When batteries are installed in the UPS or are cabinet-mounted adjacent to the UPS, the 

battery—not the UPS—dictates the designed maximum ambient temperature.
