ET 355 Monitor HL

Intended Use

The ET 355 monitor is a component. After the
monitor is installed with the NEMA 4X hatch, the

HATCH IS PART OF YOUR APPLICATION
Choose Listed (UL) conduit hubs that are rated to NEMA
!
4X/IP66 standards, are suitable for use in hazardous locations,
and provide adequate strain relief for wiring.
After making an opening in the NEMA 4X hatch, make sure that
!
there are no metal shavings in the hatch.
Properly install the monitor so that it is environmentally sealed
!
to the NEMA 4X/IP66 standard. Do not use the ET 355 monitor
with mounting options that are not rated for NEMA 4X/IP66 in
environments that require such a seal.
Properly install the ET 355 monitor with a NEMA 4X gasket that
!
is clean, undamaged, and effective.
When closing the hatch of the unit, make sure that it closes flush
!
and that the hatch screws do not bind when they are attached.
If the hatch is not closed properly, the NEMA 4X seal may be
compromised and the warranty voided.
