Connecting the AC Power Source to the Power Converter
Caution: AC power sources must be dedicated AC branch circuits. Each branch circuit must be protected by a dedicated
two-pole circuit breaker.
Caution: Do not turn on AC power until the wiring is secured.
1. Remove the plastic cover from the input power terminals and set it aside.
2. Insert the exposed ground wire lead into the power converter ground wire connection.
Ensure that only wire with insulation extends from the connector. See Figure 20 on page 42, item 1. Note that the position
of the power converter may vary on different switch models.

3. Tighten the ground wire terminal block screw.
Note: Torque to 8 in.-lb, not to exceed 10 in-lb.
4. Insert the line and neutral wire leads into the terminal block line and neutral connections. See Figure 20 on page 42,
items 2 and 3.
Ensure that you cannot see any wire lead, and that only wire with insulation extends from the connectors.
5. Tighten the line and neutral terminal block screws to 8 in.-lb torque.
Note: Do not exceed 10 in-lb torque.
6. Replace the plastic cover over the terminal block.
7. Connect the other end of the wiring to your AC power source.
Connecting the Power Converter to a DC Power Source
You can also connect the power converter to a DC power source. Several power supplies can be used. Refer to Table 11
on page 37 for the appropriate DC input ratings.
1 Ground 3 AC line
2 AC neutral
