4.9. Figure 4 shows a rear view of the
existing mounting bracket with the supplied
jumper inserted. It is critically important that
the jumper snaps into place so that it cannot
be pulled out. When properly installed, the
contacts of the jumper should be flush with
the contacts already on the connector.
Figure 5 shows this connector not inserted
fully. Failure to fully jumper contacts can
result in nuisance trips.
4.10. Install the etc-12 G Series t rip unit by
pulling down the RELEASE lever on the box
mount and inserting the brass retention pin
into the mating slot on the existing boxmount.
Pressing the retention pin against the flat
spring will cause the
RELEASE lever to
move into the locked position. Refer to
figures 6 and 7.
4.11.
Make certain that the new trip unit is
securely latched into place and its connector
is properly mated with the connector on the
box mount
