WARNING
Hazardous Voltage
Disconnect all electric power,
including remote disconnects before
servicing. Follow proper lockout/
tagout procedures to ensure the
power can not be inadvertently
energized. Failure to disconnect
power before servicing could result
in death or serious injury.
WARNING
Hazardous Voltage
Do not use any tools (i.e.
screwdriver, pliers, etc.) across the
terminals to check for power. Use a
voltmeter. Failure to disconnect
power before servicing could result
in death or serious injury.
1. For internal wiring and overload
protection on all starters, consult
the control manufacturer for
details.
2. When using thermostatic control
with a manual starter, be sure
that the electrical rating of the
thermostat is sufficient to carry
the motor current.
