Pre-installation Procedures

Lockout/Tagout the UPS Before installing the wire harnesses, use lockout and tagout safety procedures for the UPS or any attached equipment, such as high-voltage power supplies. If possible, disconnect the main output lead from the battery string to the load.

Electrical Hazard

Voltage is present in the battery cabinet even after disconnecting it from the main load. Use caution when working with the batteries.

Determine battery

Before installing the harness wires, designate a battery number to each

numbers

battery in your system. Using a volt meter to check polarity, determine

 

the most positive battery in your string (Battery 1), and count to the most

 

negative (last) battery in your string.

Determine fuse bus and midpoint bus connections (Silcon only)

Locate the 1/2-fuse bus connectors and 1/2-midpoint bus connectors on the inside roof of the cabinet.

Fuse Bus

Midpoint Bus

 

The positive fuse bus connectors and midpoint bus connectors are on the right side of the cabinet.

The negative fuse bus connectors and midpoint bus connectors are on the left side of the cabinet.
