Basler Electric BE1-51 - Manual (Page 19)

Installation
BE1-51 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 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 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.
