BE1-47N Installation

4-1

SECTION 4 • INSTALLATION

Introduction

BE1-47N 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.

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 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 shown in Figures 4-1 through 4-7. Dimensions

are shown in inches with millimeters in parenthesis.
