2.4.2 Torque Ratings
Refer to
throughout installation and use of product to maintain proper torque ratings for 682 components.
2.4.3 AC Power Cable
AC models of the 682 are shipped with the AC power cable already installed and grounded to the enclosure
.
2.4.4 DC Power Cable
DC models of the 682 do not include a power cable. Use the following steps to ground and connect a DC power cable.
1. Run the DC power cable (not included), up through the cord grip.
NOTE: The recommended wire gauge range for the power supply cable is 8-18 AWG. The recommended cable strip length
is 0.25 in (7 mm) for all 682 connectors. See
for proper torque ratings for the power cable cord grip.
2. One wire will be terminated (earth grounded), to the power supply bracket near the cord grip using the backplate
grounding screw. The backplate ground is already attached. Remove it so that the power cord ground can be on the
bottom of the stack. Torque grounding screw to 10 in-lb (1.13 N-m).
3. Connect the other two wires to the DC power supply board input screw terminal (I/P). See Table
for the input
terminal (I/P) pin assignments.
