4. If mounting device in wet environments, liquid-tight cables
or conduit fitting are required (not supplied) to ensure the
enclosure maintains a water-tight, Type 4 rating. Install the
liquid-tight cables or conduit fitting into the conduit nuts in
front of the power supply and motor connectors (See Figures
6 and 7).

WARNING: Liquid-tight cables, or conduit and fittings,
must be used to maintain Type 4 rating (See Figures 6 and 7).
If you use liquid-tight cables, follow Figure 6 and tighten the
nuts to a torque of 106 in-lbs (13 Nm).
If you use conduit fittings, follow Figure 7 and tighten the nuts to
a torque of 106 in-lbs (13 Nm).
The nuts must compress the O-ring to the body of the device.
Install the nuts with the arrow pointing towards the device, as
shown in the figures.
The components labeled with X in Figures 6 and 7 are not used
for the relative application.
5. Route supply wires through the conduit fitting into the wiring
chamber.
6. Connect the supply ground wires to the ground lug in the
wiring compartment.
NOTICE: The safety earth ground connection is marked at its
terminal using the (Figures 8, 9, and 10).
7. Connect the supply wires to the screw terminal marked L
and N (See Figures 8, 9, and 10). Use only copper wires
rated for at least 60°C. Lead wire terminals should be
tightened to a torque of 4 in-lbs (0.5 Nm).
8. Connect the motor wires to the screw terminal marked U
and V (See Figures 8, 9, and 10). Use only copper wires rated
for at least 60°C. Lead wire terminals should be tightened to
a torque of 4 in-lbs (0.5 Nm).
9. Replace the cover and tighten the four screws. For
proper sealing, the screws should be tightened to a torque of
13 in-lbs (1.5 Nm).
