Door interlock mechanism
A door interlock prevents opening the enclosure door if the
switch is in ON-position. It also works in conjunction with
the mechanism interlock, which prevents the operation to
ON-position if the enclosure door is open.
The door interlock:
A. Prevents the enclosure door from opening when the switch is
in the ON (I) position unless the interlock bypass screw is rotated
clockwise defeating the door interlock, see next page.
B. Permits opening the enclosure door with the switch in the
OFF (O) position without turning the interlock bypass screw.
C. The door will close completely but will not latch with the
switch in the OFF (O) position.
D. The door will close completely and will be held closed by the
door interlock when the switch is in the ON (I) position.
E. With the door closed completely, the mechanism interlock will
engage the door interlock when the switch is thrown from the
OFF (O) to the ON (I) position.
