Instructions
2. Periodically examine the contacts - cleaning is not required
since the contact material is a special preoxidized silver cad-
mium oxide alloy. Replacement is required only when the
contact material is almost worn down to the backing. A
complete pole consists of stationary and movable contacts
and a contact spring. This feature insures proper contact
mating which, in turn, provides maximum life.
3. Check magnet poles for foreign deposits and if present,
carefully clean pole faces with solvent.
4. Check all screws for tightness.
5. Depress test-trip button on overload relay and then reset
overload relay. This insures the relay's ability to open the
control circuit if necessary.
