Wiring Logic Power
To wire the logic power connector:
1. Prepare the incoming 24V dc logic power wires for attachment to
the logic power connector by removing 10 mm (0.375 in.) of
insulation.
2. Route the 24V dc power wires (W1 and W2) to your 1394 system
module.
3. Insert the incoming 24V dc logic power wires into the logic power
connector plug as follows and tighten the connector plug screws.
4. Gently pull on each wire to make sure it does not come out of its
terminal. Re-insert and tighten any loose wires.
5. Insert the logic power connector plug into the logic power
connector on the bottom of the system module (refer to Figure 2.1
for the connector location).
6. Go to Connecting Motor Power, Thermal Switch, and Brake.
Connecting Power Wiring for 22 kW System Modules
The 1394C-SJT22-D system module use IEC terminal blocks instead of
connectors for making power connections. You will wire the system
module using the power terminal blocks. Refer to Figure 2.2 for the
terminal block location.
IMPORTANT
Use caution not to nick, cut, or otherwise
damage strands as you remove the insulation.
