Through-the-door Disconnect
DANGER
Hazardous voltage. May cause severe injury or death.
Disconnect electric power before servicing equipment. More
than one disconnect may be required to de-energize the unit.
CAUTION
Molded case switches do not provide over-current protection.
This device may automatically open the circuit at levels above
the ampere rating of the switch.
The optional “through-the-door” disconnect is a molded
case switch with similar features of the circuit breaker. The
“through-the-door” feature provides a safety interlock that
disables power when the control panel door is opened.
Opening the through-the-door disconnect without performing
a proper machine shut-down is not recommended except in
emergencies.
The through-the-door disconnect also provides for locking
out power to the unit. To lock out power to the unit, rotate the
handle to the “Reset/Lock” position and insert a padlock or
locking device through the base of the handle. Do not lockout
the handle with the Interlock in bypass mode.
