Basler Electric BE1-32R - Manual (Page 39)

SECTION 4 • INSTALLATION
INTRODUCTION
BE1-32R and BE1-32O/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 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
Section 5, Testing 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.
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 4-1 through 4-19.
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 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 device.
