WARNING
To reduce the risks associated with electric shock or fire
which, if not avoided, could result in death or serious injury
and/or property damage.
Choose fittings and a power cable that provide adequate strain
!
relief for communications and power cables.
A cable/fitting combination will have to be found that meets local
!
electrical requirements and the requirements for a NEMA 4X
seal.
When connecting power with fixed field wiring, the power cable
!
must be double insulated. A clear, flexible insulator (supplied)
must cover the portion of the cable that is not double insulated
when connecting to a terminal strip connector.
When closing the hatch of the ET 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 invalidated.
CAUTION
To reduce the risk associated with electric shock or fire that
may result in personal injury or property damage:
After making an opening for cables, make sure that there are no
!
metal shavings in the hatch.
Use round cables that fit the diameter range of the cable fitting,
!
as shown in Table A, to meet local electrical requirements and
the requirements for a NEMA-4X/IP66 seal.
