INSTALLATION
GENERAL
When not shipped as part of a control or switchgear panel, the relays are shipped in sturdy cartons to
prevent damage during transit. Immediately upon receipt of a relay, check the model and part number
against the requisition and packing list to see that they agree. Visually inspect the relay for damage that
may have occurred during shipment. If there is evidence of damage, immediately file a claim with the
carrier and notify the Regional Sales Office, or contact the Sales Representative at Basler Electric,
Highland, Illinois.
Proper operation of the relay may be confirmed by performing the operational test procedure of Section 5.
If the relay will not be installed immediately, store the relay in its original shipping carton in a moisture and
dust-free environment.

INSTALLATION
Select the desired relay settings before putting the relay into service. Changing pickup current settings
while the relay is in service may cause tripping. Perform the following procedures to install the BE1-
50/51B-235 or BE1-50/51B-236 relay.
•
Select the desired relay settings on your new BE1-50/51B-235 or BE1-50/51B-236 relay.
•
Remove the existing ABB relay cradle.
•
Insert the new relay cradle and close the cradle latches locking the relay into the case.
•
To install the cover, position the interlocking bracket at the top of the new Basler Electric cover into
the mating receptacle at the top of the cover adapter plate. Secure the captive fastener at the bottom
of the cover.
NOTE
Be sure that the relay is hard-wired to earth ground with no smaller than 12 AWG
copper wire attached to the ground terminal on the rear of the unit case. When
the relay is configured in a system with other devices, it is recommended to use a
separate lead to the ground bus from each unit.
