APPLICATION
IMPORTANT NOTE
Series GZ and GZ…-M include pilot lights, pushbutton switches, illuminated pushbutton
switches, selector switches and (operator/actuator with contact block) combinations.
They are used in control stations, panels and enclosures used in areas made hazardous
due to the presence of flammable vapors, gases or combustible dusts.
Please read these instructions carefully before installing or maintaining this equipment.
When Series GZ and GZ…-M devices are to be installed in OEM equip
ment, refer to
Installation Instruction Sheet that came with the OEM
equipment for proper installation.
Sound electrical practices should be followed at all times and this data should be used
as a guide only.

The product is not intended to be used alone and the electrical apparatus or systems to
which it was incorporated require certification as a whole, when intended for use in
explosive atmospheres. The 3/4" NPSM or M22x1,5 thread joint of this product, and the
thread of the equipment to which it is being incorporated, must have a female 3/4"
NPSM or M22x1,5 thread meeting the requirements for threaded joints.
“GZ” operators are available in three bushing thread lengths; 25mm (0.94”),
40mm (1.57”) and 57mm (2.24”). Panel thicknesses beyond 2” require a spot face
to insure locknut can be installed from the inside of the enclosure.
CAUTION:Before installing, make sure you are compliant with area classifications, as
failure to do so may result in bodily injury, death and property damage. Do not attempt
installation until you are familiar with the following procedures. All installation must
comply with the applicable Electrical Code(s).
Make sure that the circuit is de-energized before starting installation or maintenance.
Verify that the installation is grounded. Failure to ground will create electrical shock
hazards, which can cause serious injury and or death.
