Prior to installing VRLA batteries:
1. Open the door and verify cabinet connection to site ground.
2. For initial cabinet installation, ensure all cabinet power is OFF, including the power shelf.
3. Remove the battery front retainer bracket, Figure 41.
■ Take off the four M6 screws on left and right sides of the bracket and retain hardware for
reinstallation.
Note: If cabinet configuration uses Anderson connectors, remove string bus connector from
bracket and retain hardware for reinstallation; Figure 41, Figure 42. For standard lug
connection to +RTN and -48 V terminals (Figure 44), set cables clear of batteries and do
not remove protective covers until ready to connect.
