Route the DC cables from the UPS through the bottom of the classic battery cabinet and connect the battery cables (N, DC+, DC-). Use lock washers (not provided) when connecting the DC cables.
Do not disconnect the battery connectors under load under any circumstances. Battery replacement and external battery cabinet installation shall be handled by qualified SERVICE PERSONNEL only. Connection
Battery cabinets that are not supplied with an incorporated DC output disconnect device must have an appropriate disconnect device provided external to the cabinet.
Draw a wiring schematic representing the cables connected between the battery cabinet''s output terminal blocks and any external disconnect device, junction box and/or load/rectifier.
Route the ground wire (from the field kit) from the ground stud in the battery cabinet, under the lower right‐hand battery tray, through the access hole in the side panel of the UPS, and attach to the ground stud in the UPS
Battery cabinets that are not supplied with an incorporated DC output disconnect device must have an appropriate disconnect device provided external to the cabinet.
Before installing the battery cabinet, read and understand how this manual applies to the system being installed. Use the procedures and illustrations in this section to create a logical plan for installing the battery cabinet.
Each Liebert® APM2 Battery Cabinet contains a string of valve regulated lead-acid batteries connected in series and placed in a matching cabinet. Multiple battery cabinets can be combined into systems by connecting
• The battery cabinet contains an internal energy source. Hazardous voltage can be present even when the UPS system is disconnected from the utility/ mains supply. Before installing or servicing the UPS system, ensure
Verify that no current will flow when the battery is connected or disconnected by opening battery disconnects (if available) or adjusting the system to match battery voltage.
