1.2.2 UPS Cable Connection Reference
Context
WARNING
● Keep away from cabinets when preparing cables to prevent cable scraps from
entering the cabinets. Cable scraps may cause ignition during power-on and
result in personal injury and device damage.
● After installing cables, clean the cabinet top, bottom, copper bar wiring
positions, and other positions. Ensure that there is no dust or scraps inside and
around cabinets.
● Prepare terminals onsite. The length of the copper wire should be the same as
that of the part of the terminal that covers the conductor.
Procedure
Step 1 Route a cable into the cabinet and bind it to a nearby beam.
Step 2 Pull the cable to the copper bar to which the cable is to be connected, determine
the cable length, and mark the cable at the position where the cable is to be cut.
Step 3 Pull the marked cable out of the cabinet, cut the cable from the marked position,
strip the cable, and crimp a terminal.
