Installation

CAUTION!

The qualified service person must take these precautions:

1.Wear protective clothing, such as rubber gloves and boots and protective eye wear. Batteries contain caustic acids and toxic materials and can rupture or leak if mistreated. Remove rings, metal wristwatches, other metal objects and jewellery. Do not carry metal objects in your pockets where the objects can fall into the battery cabinet.

2.Tools must have insulated handles and must be insulated so that they will not short battery terminals. Do not allow a tool to short between individual or separate battery terminals or to the cabinet or rack. Do not lay tools or metal parts on top of the batteries, and do not lay them where they could fall onto the batteries or into the cabinet.

3.Install the batteries as shown on the drawing provided with the batteries. When connecting cables, never allow a cable to short across a battery’s terminals, the string of batteries, or to the cabinet or rack.

4.Align the cables on the battery terminals so that the cable lug will not contact any part of the cabinet or rack, even if the battery is moved. Keep the cable away from any sharp metal edges.

5.Install the battery cables so they cannot be pinched be the UPS or battery cabinet doors.

6.Do not connect the battery terminal to ground (earth). If any battery terminal is inadvertently grounded, remove the source of the ground. Contacting any part of a grounded battery can cause a risk of electric shock.

7.To reduce the risk of fire or electric shock, install the batteries in a temperature and humidity controlled indoor area, free of conductive contaminants.

8.Battery system chassis ground (earth) must be connected to the UPS chassis ground (earth). If you use conduit, this ground conductor must be routed in the same conduit as the battery conductors.

9.Where conductors may be exposed to physical damage, protect the conductors in accordance with all applicable codes.

10.If you are replacing batteries or repairing battery connections, shut off the UPS and remove both AC and DC power.

Battery Installation Guidelines:

•Refer to any instructions provided with the batteries, battery breaker and pre-charge /discharge switch.

•External batteries require a fused disconnect or a DC battery breaker. There should be a disconnecting means for each battery string. The external battery fuse protects the battery cables. Size the cables based on the overcurrent protection device.

•The battery cables must be sized for a total maximum voltage drop of 2.0 VDC at the rated DC current.

•Wherever conductors may be exposed to physical damage, protect the conductors in accordance with any applicable codes. This includes battery cables between the UPS and the battery system and cables between battery cabinets or racks.

•APC recommends the routing of battery cables through flexible conduits. Install flexible conduits for battery cables according to local or national codes.

•The battery system ground (earth) must be connected to the UPS chassis ground (earth). This ground conductor must be routed with the battery cables.
