Wiring Connections - Eaton CROUSE-HINDS Serie Nformación De Instalación Y Mantenimiento

WIRING CONNECTIONS

1. Check tightness of all internal fasteners of enclosure, including those securing
electrical equipment and mounting plate before wiring. Fasteners could loosen from
shipment and/or installation.
2. Connect grounding conductors to the ground lugs on the mounting plate. Pull all
phase conductors into enclosure and make connections as shown in breaker and
starter manufacturer's instructions. All electrical connections should be tightened
to torque values specified in manufacturer's literature and comply with the National
Electrical Code and all local codes. Verify torque of any existing wiring.
3. Route ground and phase conductors to avoid any sharp edges and provide proper
wire bend clearance and wire spacing.
4. When connecting control wires to cover route wires to prevent damage when
opening and closing the cover. Route wires to avoid the circuit breaker/HMCP and
starter operators. Always maintain the required electrical spacing.
5. Test wiring for correctness with continuity checks and also for unwanted ground with
an insulation resistance check.
See Table A1 for wire sizing and torque values.
Reference IF 1149 for further wiring instructions and diagrams.
SEALS
Pour sealing compound into approved sealing fittings in accordance with the
manufacturer's instructions. Verify correct conduit seal selected for wire fill based on
wiring method.
EMPX OPERATOR INSTALLATION
Crouse-Hinds series EMPX operators are available for use with the EIC motor control
series. EMPX operators can be installed before or after components are secured to the
mounting plate. Consult Eaton's Crouse-Hinds Division's catalog for details. Reference IF
1857 for further information on EMPX operators.
To avoid risk to personnel, electrical power must be OFF and the area free from
flammable gases or vapors before and during installation and maintenance.
Check wire routing by opening cover as wide as possible and then closely observe
whether wires rub on the flange surface, or any other surfaces/edges that could cause
damage.
To maintain environmental ratings, new EMPX operators installed in the field
must be secured with a locknut to maintain NEMA 4X rating.
OTHER ELECTRICAL OPTIONS
See Table 2 for other components that can be added to an EIC enclosure. See the EIC
replacement parts list for information on how to separately order replacement parts.
EIC MAINTENANCE
To avoid fire or explosion, always disconnect primary power source and verify area
is free from flammable gases or vapors before opening enclosure for inspection or
service.
1. Frequent inspection should be made of the enclosure, operators and internal
components. A maintenance schedule for maintenance checks should be
determined by the environment and frequency of use. It is recommended that it
should be at least once a year.
2. Perform visual, electrical and mechanical checks on all components on a regular
basis.
• Visually check for undue heating evidenced by discoloration of wires or other
components, damaged or worn parts or leakage evidenced by water or
corrosion in the interior.
• Electrically check to make sure that all connections are clean and tight and that
contacts in the components make or break as required.
• Mechanically check that all parts are properly assembled, and operating
mechanisms move freely.

3. A Waterguard desiccant packet has been installed in all fully populated EIC units at
the factory. The purpose of the desiccant is to absorb and remove water on contact
or from the atmosphere, and protect the enclosed equipment from damage. The
desiccant packet will expand 3 to 4 times its original size. Desiccant should be
checked and replaced at regular equipment service intervals or every 3 to 6 months.
Always keep dessicant pack away from wiring, components, etc. A Waterguard
desiccant is non-toxic, emits no fumes and generates no heat during use. No
gloves, masks or special clothing is required to handle this product.
4. If the gasket becomes worn, cut or damaged, it can be replaced. Contact factory for
replacement kit and follow installation instructions in IF 1616.
Replacement parts are available through Eaton's Crouse-Hinds Division.
5. An Electrical Preventive Maintenance Program as described in the National Fire
Protection Association Bulletin NFPA No. 70B is recommended.
