9171300990 Rev V BE1-87T Installation 4-1
SECTION 4 • INSTALLATION
General
When not shipped as part of a control or a switchgear panel, the relay is shipped in a sturdy carton to
prevent damage during transit. Immediately upon receipt of a relay, check the model and Style Number
against the requisition and packing list to see that they agree. Visually inspect the relay for damage that
may have occurred during shipment. If there is evidence of damage, immediately file a claim with the
carrier and notify the Regional Sales Office, or contact a 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. For more information, see Storage in Section 4. When the relay is to
be placed in service, it is recommended that the Verification Tests, shown in Section 5, be performed
prior to installation.
Relay Operating Precautions
Before installation or operation of the relay, note the following precautions.
1. A minimum of 0.2 A in the output circuit is required to ensure operation of current-operated
targets.
2. The relay is a solid-state device and has been type tested in accordance with the requirements
defined under Dielectric Test. If a wiring insulation test is required on the panel assembly in
which the relay is to be installed, it is suggested that the connection plugs (or paddles) of the
relay be removed and the cradle withdrawn from the case so as not to produce false readings
during the wiring insulation test.
3. 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, testing, or servicing. Be sure that
connection plugs are in place before replacing the front cover.
CAUTION
To prevent possible false tripping, the upper connection plug should be in
place prior to removing or installing the lower connection plug.
4. Thumbwheel switches should not be changed while the relay is in service. Momentary
undesired indications and outputs may occur.
WARNING!
The TEST PROCEDURES require familiarity with solid-state relay circuits. To
avoid personal injury or equipment damage, do not proceed unless qualified in
this area.
NOTE
Several procedures in this manual require the removal of printed circuit
boards. Refer to the topic Relay Disassembly before installing the BE1-87T.
