Terminate Wiring

Step 1:
Route the load wires to the DRd rack(s) through the conduit previously installed.
Step 2:
Prepare the load wires for termination:
a: Label each wire in the set with circuit designation.
b: Separate load circuit wires into ground, neutral and hot/live wire bundles.
Step 3:
Strip 5/8” (16mm) of insulation from the end of each load wire.
Step 4:
Route each load hot/live wire to its individual load output connection.
Step 5:
Strip the neutral wire to the length indicated in the table above and terminate to
the neutral terminal assembly. Torque to the recommended value also indicated
in the table above. For 230 VAC DRd racks, the neutral bus is located on the line
input feed side of the rack.
Step 6:
Strip the ground/earth wires to the length indicated in the table above and
terminate to the ground bus terminal. Torque to the recommended value also
indicated in the table above.
N o t e :
Plan load wiring appropriately to avoid splicing wiring in the racks. Only one load
wire per load terminal.
C A U T I O N :
Dress and terminate wires neatly and avoid leaving extra wire inside the rack. Too
much clutter (especially along the right side of the rack) can restrict air circulation
and reduce cooling efficiency. If cabling interferes with airflow during operation,
the rack may be forced to shut down due to overheating.
Load wires should not cross between racks. Instead, they should enter the rack in
which they will be terminated. Hot/Live and neutral load wiring must follow the
same conduit/path for each circuit.

N o t e :
Ground connections must use all metal nuts and lock washers.
a: Insert the wire on the back side of the lugs.
b: Torque the lug screw to the recommended
value indicated in the table below.
