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. 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 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. When
relay is to be placed in service, it is recommended that the operational test procedure (Section 5,
Testing)
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. If a wiring insulation test is required, remove the
connection plugs and withdraw the cradle from its case.
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, test, or service.
4.
Be sure 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.
DIELECTRIC TEST
In accordance with IEC 255-5 and ANSI/IEEE C37.90, one minute dielectric (high
potential) tests as follows:
All circuits to ground: 2121 Vdc
Input to output circuits:
1500 Vac or 2121 Vdc
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 provided in Figures
4-1 through 4-6.
