APPLICATION PRECAUTIONS
1)
Verify that the voltage and current applied is within the specified ratings. (See application
table, page 5).
2)
When the contactor is used with an induction heater facility, the switching life of the vacuum
interrupter is approximately 250,000 operations. The vacuum interrupter should be replaced
after 250,000 operations.
3)
When the contactor is applied to a capacitor load, be sure to use a space heater to keep
the temperature above the dew point and prevent condensation. Be sure to use a heater
adequately sized for the compartment in which the contactor is installed. The contactor
should always be applied with a protective power fuse.
INSTALLATION
During installation, protect the contactor from dust and falling debris.
The following precautions should be taken,
1)
The mounting surface should be horizontal (level:
±
1 mm). If the mounting surface is not
level, adjust with spacers or shims.
2)
The contactor base has four (4) mounting holes. Use M8 or 5/16 bolts to securely mount
the contactor.
3)
In wiring the main circuit, wires should be given sufficient length to be flexible for service.
The ground wires should be #10 AWG or larger.
4)
Avoid touching the surface of the vacuum interrupter with soiled hands. You can damage
the silicon finish on the interrupter. If the interrupter becomes dirty, simply clean it with a
non-tracking cleaner such as rubbing alcohol.
