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.
