EIC combination line starters
Installation & maintenance information
APPLICATION
EIC combination line starters are used for general motor control and circuit protection in
hazardous environments. They provide motor branch circuit protection, motor running
protection, under voltage protection and remote starting and stopping by means of a
combination of thermal magnetic circuit breakers and magnetic motor starters.
INSTALLATION
To avoid risk of electrical shock, electrical power must be OFF before and during
installation and maintenance.
1. Select a mounting location that will provide suitable strength and rigidity for
supporting all contained wiring, components and control devices. Figure 1 and Table
1 show the mounting dimensions.

2. Securely fasten the enclosure to the mounting location, then attach into cable or
conduit system. Install approved conduit sealing fittings when required by the
National Electrical Code plus any other applicable standards.
To avoid risk of ignition:
• Hazardous location information specifying class and group listing of each device
is marked on the nameplate of each enclosure. Class and group listing for any
device penetrating the enclosure must be suitable for the classification of the
location in which the enclosure is installed.
• All unused conduit openings must be plugged. Listed plug must engage a
minimum of five (5) full threads and be a minimum of 1/8" thick.
• In Class I, Division 1, Groups B, C, D locations, conduit sealing fittings MUST
be installed in each attached conduit run within 18" of the enclosure to comply
with the latest edition of the National Electrical Code Section 501.15 and/or
502.15 plus any other applicable code.
• Hammers or prying tools must not be allowed to damage the flat ground joint
surfaces or cover gasket.
3. Pull wires into enclosure, making sure they are long enough to make the required
connections. Make all electrical connections. The internal grounding terminals (lugs)
shall be used as equipment grounding means. The external ground terminal (lug) is
only a supplemental bonding connection.
4. Test wiring for correctness with continuity checks and also for unwanted grounds with
insulation resistance tester.
To avoid risk of ignition:
Clean both ground joint surfaces of body and cover before closing. Dirt or foreign
material must not accumulate on flat ground joint surfaces. Surfaces must seat fully
against each other to provide a proper explosionproof seal.

EIC enclosures utilize Eaton's Crouse-Hinds series ECP classified NEMA 7 and NEMA
9 enclosures. These enclosures are suitable for use in Class I, Groups B, C, D; Class
II, Groups E, F , G; and Class III hazardous (classified) areas as defined by the National
Electrical Code (NEC) Article 500.
®
EIC enclosures should be installed, inspected and serviced by qualified and competent
personnel.

To avoid nuisance tripping, ensure that EIC enclosure is mounted in a shaded area,
avoiding direct sunlight.
5. Close the cover, making sure that cover and body ground joint surfaces are clean
with no damage or scratches. Fully tighten all cover bolts to torque values per Table
A2.

6. Pour sealing compound into sealing fittings (when required) in accordance with the
instructions supplied with each of the approved fittings and sealing compound. We
recommend Chico
To maintain environmental ratings, EIC enclosure shall be installed in the
horizontal position; vertical position (facing up) is not permitted.
BREATHER AND DRAIN
When used, check breather and/or drain to be certain that they are suitable for the
hazardous location (class and group), as well as for the environmental ratings in which
they are being installed.
For installation or removal of breather and/or drain, reference IF 843.
GROUNDING AND BONDING
Grounding and bonding of the conduit and equipment is required by the National Electrical
Code. A grounding conductor, when used, must be connected to the grounding lug(s),
furnished. Suffix S214 provides an external ground lug.
To avoid the risk of explosion, EIC enclosures must be securely attached into
a permanently grounded system in accordance with Articles 501 and 502 of the
National Electrical Code. The internal grounding lug(s) shall be used as the primary
equipment ground.
Determine the type of distribution system to be used that complies with NEC
requirements and ensures grounding continuity.
All conductive materials that enclose the electrical conductors, attached equipment or
forming part of such equipment, must be grounded. A permanent conducting connection
must be made between all such equipment and the earth.
INSTALLATION OF INTERNAL COMPONENTS
If an unpopulated EIC (without circuit breaker/HMCP or motor starter) is supplied, the
addition of components/devices is required. Also, the addition of components to the
internal operators for the circuit breaker/HMCP and motor starter must be installed. See
Table 2 for assembly details.
NOTE: The interior mounting plate may be removed to aid in the installation of the circuit
breaker/HMCP , motor starter and other optional equipment.
