EIC ATEX 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.

Size C 12 (305) 36 (914)
*Use M10 bolts for size A and M13 bolts for sizes B and C.
†External ground lug hole provided for all units. Hole is located on hinge side of body for sizes B and C.

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
installation codes 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.
• Unused entries must be plugged using suitably certified Ex d IIC Gb and Ex tb
IIIC Db blanking elements.
• Entry to the enclosure must be made by suitably certified Ex d IIC Gb and Ex
tb IIIC Db cable gland or suitably certified conduit seal installed at the enclosure
wall.
• For hazardous rated locations, all cable entries must be fitted with appropriately
rated cable glands as per local code requirements.
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.
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.

To avoid nuisance tripping, ensure that EIC enclosure is mounted in a shaded
area, avoiding direct sunlight.
6. Seal all wiring using appropriate glands.

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, 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 installation
codes. A grounding conductor, when used, must be connected to the grounding lug(s),
furnished.
Determine the type of distribution system to be used that complies with national
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.
