Wiring high-voltage power

WARNING
Hazardous voltage!
Before making electrical connections, lock open the supply-power dis-
connect switch. Failure to do so could result in death or serious injury.
CAUTION
Use copper conductors only!
Unit terminals are designed to accept copper conductors only. Other
conductors may cause equipment damage.
To connect high-voltage power wires:
1. Lock open the supply-power disconnect switch.
2. At the top right corner of the enclosure, remove the knockout and
install 0.5-inch (13 mm) conduit (see Figure 29).
Figure 29. Knockout for high-voltage power wires
3. Open or remove the Tracer MP581 door if it is already installed.
4. Inside of the enclosure at the top-right corner, remove the high-volt-
age area cover plate.
5. Feed the high-voltage power wires into the enclosure.
6. Connect the line wire to the L terminal as shown in Figure 30 on page
61.
7. Connect the neutral wire to the N terminal.
8. Connect the green ground wire to the chassis ground screw. The
ground wire must be continuous back to the circuit-breaker panel.
9. Replace the cover plate.
