INSTALLATION
INSPECTION
At the time of installation, the relay should be inspected for tarnished contacts, loose screws, or other
imperfections. If any trouble is found, it should be corrected; see MAINTENANCE. Check the
nameplate for model number and rating.
LOCATION
The location should be clean and dry, free from dust and excessive vibration, and well lighted to
facilitate inspection and testing.
MOUNTING
The relay should be mounted on a vertical surface. The outline and panel drilling dimensions are
shown in Fig. 14 for relay Types IAV51D, IAV52D, and IAV52C. Fig. 15 shows outline and panel
drilling for relay Types IAV51K and IAV52K.
CONNECTIONS
Internal connections are shown in Figs. 3 to 7 for the various relays.
GROUND CONNECTIONS
One of the mounting studs or screws should be permanently grounded by a conductor not less than
No. 12 B&S gage copper wire or its equivalent.
OPERATION
Before the relay is put in service, the pickup-voltage and time-voltage tests described under
ACCEPTANCE TESTS (ELECTRICAL TESTS) should be made to determine that factory
adjustments have not been disturbed.
The relay may be tested while mounted on the panel, either from its own or another source of power,
by inserting a separate testing plug in place of the connecting plug. Or, the cradle can be drawn out
and replaced by another that has been laboratory tested.
