4.
When the stop position is reached, the locking mechanism will release. The relay will
now slide out of the case when pulled from its handle. To free the relay, it may
sometimes be necessary to adjust the handle position slightly.
Figure 6: Sliding the Unit out of the Case
To insert the unit into the case:
1.
Ensure that the model number on the left side of the relay matches the requirements
of the installation.
2.
Raise the locking handle to the highest position.
3.
Hold the unit immediately in front of the case and align the rolling guide pins (near the
hinges of the relay’s handle) with the case’s guide slots.
4.
Slide the unit into the case until the guide pins on the unit have engaged the guide
slots on either side of the case.
5.
Once fully inserted, grasp the handle from its center and rotate it down from the
raised position towards the bottom of the relay.
6.
Once the unit is fully inserted the latch will be heard to click, locking the handle in the
final position. The unit is mechanically held in the case by the handle’s rolling pins,
which cannot be fully lowered to the locked position until the electrical connections
are completely mated.
No special ventilation requirements need to be observed during the
installation of the unit. The unit does not require cleaning.
Ethernet connection
If using the 750/760 with the Ethernet 10Base-T option, ensure that the network cable is
disconnected from the rear RJ45 connector before removing the unit from the case. This
prevents any damage to the connector.
The unit may also be removed from the case with the network cable connector still
attached to the rear RJ45 connector, provided that there is at least 16" of network cable
available when removing the unit from the case. This extra length allows the network cable
to be disconnected from the RJ45 connector from the front of the switchgear panel. Once
disconnected, the cable can be left hanging safely outside the case for re-inserting the unit
back into the case.
