Basler Electric BE1-87B - Manual (Page 45)

SECTION 4
• INSTALLATION
General
When not shipped as part of a control or switchgear panel, the 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 damage that may have occurred
during shipment. If there is evidence of damage, file a claim with the carrier and notify the regional sales
office, or contact the sales representative at Basler Electric, Highland, Illinois.
In the event the relay is not to be installed immediately, store the relay in its original shipping carton in a
moisture and dust free environment. When the BE1-87B is to be placed in service, it is recommended that
the procedures outlined in Section 5, Testing be performed prior to installation.
Relay Operating Precautions
Before installation or operation of the relay, note the following precautions:
1. The relay is a solid-state device. If a wiring insulation test is required, remove the connection plugs
and withdraw the cradle from its case.
2. 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.
Be sure that the relay case is hard wired to earth ground using the ground terminal on the rear of the unit.
It is recommended to use a separate ground lead to the ground bus for each relay.
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 4-16. Dimensions are shown in inches with millimeters in parenthesis.
NOTE
All relay dimensional drawings show cases with optional CT Test pushbutton
access.
