Wiring the DC Power Source
For connections from the power converter to earth ground, use shielded 14-AWG stranded copper wire.
2. Measure a length of twisted-pair copper wire long enough to connect the power converter to the DC power
source.
For DC connections from the power converter to the DC source, use 10-AWG twisted-pair copper wire.
3. Using a wire-stripping tool, strip the ground wire and both ends of the twisted pair wires to 0.25 inch (6.3
mm) ± 0.02 inch (0.5 mm). Do not strip more than 0.27 inch (6.8 mm) of insulation from the wires.
Stripping more than the recommended amount of wire can leave exposed wire from the power and relay
connector after installation.
4. Connect one end of the stranded copper wire to a grounded bare metal surface, such as a ground bus, a
grounded DIN rail, or a grounded bare rack.
5. Insert the other end of the exposed ground wire lead into the earth-ground wire connection on the power
converter terminal block. Note that the position of the power converter may vary on different switch
models.
6. Tighten the earth-ground wire connection terminal block screw.
Note Torque to 8 in.-lb, not to exceed 10 in-lb.
Warning An exposed wire lead from a DC-input power source can conduct harmful levels of electricity. Be sure that
no exposed portion of the DC-input power source wire extends from the power and relay connector. Statement
122
7. Insert the twisted-pair wire leads into the terminal block line and neutral connections. Insert the wire lead
into the neutral wire connection and the wire\ lead into the line wire connection. Ensure that only wire
with insulation extends from the connectors.
8. Tighten the line and neutral terminal block screws.
Note Torque to 8 in.-lb, not to exceed 10 in-lb.
9. Connect the red wire to the positive pole of the DC power source, and connect the black wire to the return
pole. Ensure that each pole has a current-limiting-type fuse rated to 30 Amp.
Wiring the DC Power Source
Read these cautions and warnings before wiring the switch the DC power source.
Warning
This product relies on the building s installation for short-circuit (overcurrent) protection. Ensure that
the protective device is rated not greater than: 15A. Statement 1005
