ELECTRICAL CONNECTIONS
GROUNDING
To reduce the risk of electric shock the
motor must be securely and adequately grounded to a grounded metal race-
way system, or by using a separate grounding wire connected to bare metal
on the motor frame, or to the grounding screw located inside motor terminal
box, or other suitable means. Refer to National Electric Code (NEC Article 250
{Grounding}) for additional information.)
All wiring should be performed by a quali-
fied electrician and in accordance with the national electric code and local
electric codes.
Failure to connect the motor frame to
equipment grounding conductor by using green screw may result in serious
electrical shock.
WIRING CONNECTIONS
1. This unit is not water proof and is not intended to be used in
showers, saunas, or other potentially wet locations. The motor
is designed to be used in a clean dry location with access to an
adequate supply of cooling air. Ambient temperature around the
motor should not exceed 104F (40C). For outdoor installations
motor must be protected by a cover that does not block airflow to
and around the motor. This unit is not weatherproof nor is it able to
be submersed in water, or any other liquid.
2. Single phase motors, 3/4 - 2 HP, are dual voltage and can be con-
nected for 115V or 230V service.
3. If the motor wiring must be changed to conform to your specific
voltage requirements then the motor should be rewired. For proper
electrical connections, refer to the connection diagram located on
the nameplate of the motor or the one in Figure 7. Make sure con-
nections are correct for the voltage being supplied to the motor.
MOTOR PROTECTION
1. All motors have built-in thermal protection for all voltages. The
overload protects the motor against burnout from overload of low
voltage, high voltage and other causes. The device is automatic
and resets itself once the temperature has dropped to a safe point.
Frequent tripping of the device indicates trouble in the motor or
power lines and immediate attention is needed. The device should
never be tampered with unless the trouble is located and cor-
rected.
2. Undersize wiring can cause motor failure (low voltage), frequent
cut-out of motor overload protector, television interference and
even fire. Make certain the wiring is adequately sized (Figure
9), well insulated and connected to a separate circuit outside the
house in case of fire.
