INSTALLATION
RECEIPT AND INSPECTION
BE1-50/51B-229 Overcurrent Relays are shipped in sturdy cartons to prevent damage during transit.
Upon receipt of a relay, check the model and part number against the requisition and packing list. Inspect
the relay for any damage that may have occurred during shipment. If there is evidence of damage, file a
claim with the carrier, and notify your regional sales office or a sales representative at Basler Electric.
If the relay will not be installed immediately, place the relay in its original shipping carton and store in a
dry, dust-free environment.
Proper relay operation may be confirmed by performing the test procedures of Section 5, Testing .

Be sure that the relay is hard-wired to earth ground with no smaller than 12 AWG

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.
