Installation

BE1-51/27R relays are shipped in sturdy cartons to prevent damage during transit. Upon receipt of a
relay, check the model and style number against the requisition and packing list to see that they agree.
Inspect the relay for shipping damage. If there is evidence of damage, file a claim with the carrier, and
notify your sales representative or Basler Electric.

If the relay will not be installed immediately, store it in its original shipping carton in a moisture- and dust-
free environment. Before placing the relay in service, it is recommended that the test procedures of the
Tests and Adjustments
chapter be performed.

Relay Operating Guidelines and Precautions

Before installing or operating the relay, note the following guidelines and precautions:

For proper current operated target operation, a minimum current of 200 milliamperes must flow
through the output trip circuit.

If a wiring insulation test is required, remove the connection plugs and withdraw the relay from its
case.

Caution

When the connection plugs are removed, the relay is disconnected
from the operating circuit and will not provide system protection.
Always be sure that external operating (monitored) conditions are
stable before removing a relay for inspection, test, or service.

Note

Be sure that the BE1-51/27R is hard-wired to earth ground with no
smaller than 12 AWG copper wire attached to the ground terminal on
the rear of the case. When the BE1-51/27R is configured in a system
with other devices, it is recommended to use a separate lead to the
ground bus from each device.

Mounting

Because the relay is of solid-state design, it does not have to be mounted vertically. Any convenient
mounting angle may be chosen. Refer to the following figures for relay outline dimensions and panel
drilling diagrams.
