Installing Short-Circuiting Copper Bars – Dc Power Distribution Box - Huawei OptiX OSN 3500 Quick Installation Manual

•Installing Short-circuiting Copper Bars – DC Power Distribution Box (DPD63-8-8 PDU)
DANGER
Do not install the short-circuiting copper bar in the power output areas.
NOTE
Whether to install short-circuiting copper bars and horizontal short-circuiting copper plates in the power input area
depends on the power supply in the equipment room. Short-circuiting copper bars and horizontal short-circuiting copper
plates must be installed together. Installation of only short-circuiting copper bars or horizontal short-circuiting copper
plates is not allowed.
Short-circuiting copper bars and horizontal short-circuiting copper plates can be removed in a way similar to installation.
Confirm the input terminal groups that need to be short-circuited. Install 2-in-1 short-circuiting copper bars on the
negative input terminals and tighten the screws that fix the bars onto the air breakers. Ensure that appropriate bars
are used on the right or left side of the PDU.
Install 2-in-1 horizontal short-circuiting copper plates on the mapping positive input terminals in the middle of the PDU.
Install power cables (blue) on the negative input terminals and power ground cables (black) on the positive input
terminals.
CAUTION
1. When the input terminals are not short-circuited, all cables that are installed
on both the positive and negative input terminals use cord end terminals.
When the input terminals are short-circuited, the cables that are installed on
the negative input terminals use two-hole OT terminals and the cables that
are installed on the positive input terminals use cord end terminals.
2. To short-circuit an input terminal group, the negative and positive input
terminals of the group must be short-circuited at the same time.
3. Check the screws on the air breakers and all screws should be tightened.
Pull the cables that are installed on the input terminals and no cable should
be loosened or removed.
CAUTION
When installing cables on the short-circuited negative input
terminals, ensure that the protruding part of each OT
terminal faces the screws. In this way, the cables will not
be pressed and the screws can be sufficiently tightened.
CAUTION
After the horizontal short-circuiting copper plates
are installed, plug the holes on the plates.
