Unpacking and Inspection
Carefully unpack the UPS and battery modules, making sure to retain the packaging materials. Examine each unit carefully for any signs of damage and immediately notify your service representative if damage is present.
UPS and Battery Module Storage
If you plan to store the UPS or battery modules prior to use, store them in a cool, dry environment. Storage temperature should not exceed 35_C (95_F) in order to preserve battery life. For longer term storage, energize the UPS and battery module for approximately 8 hours every 90 days in order to maintain battery charge.
Whenever the units are not energized, make sure the circuit breaker on all battery modules is returned to the OFF (O) position (see Figure5 on page 26).
Important Installation Notes - Read Before Installing the UPS
UPS applications requiring a serial interface or standard LAN interface may connect directly to the 25;pin UPS alarm interface. PBX systems such as the DEFINITYr Communications System and processor;based applications such as Call Center, Conversant, or Voice Processing that use a Remote Management Board require an isolated contact;closure interface that is provided by a special UPS Alarm Interface Adapter (PEC 24433).
CAUTION For alarm connection to all systems that require a contact closure versus a serial interface, except 3B2, do not connect the alarms without first installing the alarm interface adapter. 3B2 systems require a different adapter shown on the following page. Failure to install the alarm adapter will have an adverse effect on computer system operation.
Set the UPS for the required communication configuration according to Chapter 5, •Communication" on page 45 before connecting the load. Failure to do this will require that the load be disconnected prior to setting the communication interface for proper alarm reporting configuration.
