Installation
BE1-81O/U 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 confirm that they agree.
Inspect the relay for shipping damage. If there is evidence of damage, file a claim with the carrier and
notify Basler Electric.
If the relay will not be installed immediately, place the relay in its original shipping carton and store in a
moisture- and dust-free environment.
Operating Precautions
Before installing the relay, note the following precautions.
•
A minimum of 200 milliamperes in the output contact circuit is required to ensure reliable
operation of current operated targets.
•
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 conditions are stable
before removing a relay from service. Also, ensure that connection plugs are installed before
replacing the case 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 relay 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 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. Relay outline dimensions and panel drilling diagrams are illustrated in
Figures 6 through 24.
