Electrical Connection
Ensure that wiring conforms to all applicable local and national electrical codes and install
unit(s) according to relevant national and local safety codes.
Use a 1-1/8”, open-end wrench to hold the hex on the electrical connection while conduit
or conduit fitting is being tightened.
The electrical switch element capsule assembly contains UL Listed and CSA Certified
factory-sealed leads. A conduit seal is not required to preserve explosion proof integrity.
Electrical leads are marked NC (Normally Closed), NO (Normally Open) and C (Common).
Electrical switching elements are snap-action and are either SPDT or DPDT (2-SPDT) set to
actuate simultaneously.

Pressure
Do not use a pipe wrench or strap wrench on the round body nor an open-end
wrench on the hex pressure port while tightening the conduit connection,
because the hermetically sealed switching element capsule has been
precisely positioned and locked during manufacture. Excessive force could
overcome the lock and cause movement which will adversely affect operation
or render the pressure switch inoperative. Should movement occur, factory
calibration must be performed in order to restore normal operation.
