Warning!
To avoid potential electric shock, follow National Electric Code safety practices
or your local code when wiring this unit to a power source and to peripheral
devices. Failure to do so could result in injury or death. All ac power connections
must be in accordance with published CE directives. All wiring procedures must
be performed with the power off.
The NEMA 4X enclosure contains an integral wiring compartment located in the smaller end
of the enclosure. Two ¾" female NPT conduit entries are available for separate power and
signal wiring. For all hazardous area installations, make sure to use an agency-approved
fitting at each conduit entry. The cable entry device shall be of a certified flameproof type,
suitable for the conditions of use and correctly installed. The degree of protection of at least
IP66 to EN 60529 is only achieved if certified cable entries are used that are suitable for the
application and correctly installed.
Unused apertures shall be closed with suitable blanking elements.
If conduit seals are used, they must be installed within 457 mm (18") of the enclosure.
