INSTALLATION AND TESTING
GENERAL
When not shipped as part of a control or 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 evident 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. When the relay is to be placed in service, it is recommended that the
verification tests (given later in this section) 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 the FUNCTION
targets.
2.
Always reset targets by means of the target reset switch.
3.
The relay is a solid state device and has been type tested in accordance with the
requirements defined below under DIELECTRIC TEST. If a wiring insulation test is
required on the panel assembly in which this relay is to be installed, it is suggested that
the connecting plugs (or paddles) of the relay be removed and the cradle withdrawn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.
4.
When the connecting 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 connecting plugs are in place before replacing the front cover.
DIELECTRIC TEST
1000 Vac at 60 hertz for one minute may be applied across output terminal pairs in accordance with IEC
255-5 and ANSI/IEEE C37.90-1989 (Dielectric Test). Maximum applied voltage must be no greater than 300
volts where MOV suppressors are used. Terminals 11 and 12 have MOV suppressors installed between
terminals and ground. Terminals 3 and 4 have one MOV suppressor installed between the terminals. All
terminals have decoupling capacitors installed between terminals and ground. According, a leakage current
of approximately 2.0 milliamperes per terminal is to be expected when high potting at 1000 Vac, 60 hertz.
1500 Vac at 60 hertz for one minute may be applied across current sensing input terminals, between circuit
groups, and between circuit groups and chassis ground in accordance with IEC 255-5 and ANSI/IEEE
C37.90-1989 (Dielectric Test).
MOUNTING
The BE1-51C relay is supplied in a standard S1 size drawout case. Figure 6-1 provides the outline
dimensions for this case. The panel drilling and cutout dimensions for this case are provided in Figure 6-2.
The relay does not have to be mounted vertically. Any convenient mounting angle may be chosen.
