JKSSS+ Series

2.3 - 4.2KV

Always keep the controller upright while lifting. Some controller sections may contain

heavy or special equipment that will cause the center of gravity to be off-center. Rigging

lengths should be adjusted to maintain the controller in an upright position. The angle

between the lifting cables and vertical should not be allowed to exceed 45 degrees

(Fig. 2). Ropes or cables should not pass through the holes in lifting angles or eye-

bolts. Slings with safety hooks or shackles of adequate load rating should be used.

2.2 - Initial Inspection

• Make a complete visual check of the unit for damage which

may have occurred during shipping and handling. Do not

attempt to continue installation or start up the unit if it is

damaged.

• Check for loose mechanical assemblies or broken wires

which may have occurred during transportation or handling.

Loose electrical connections will increase resistance and

cause the unit to function improperly.

• Prior to beginning the installation, verify that the motor and

JKSSS unit are rated for the proper amperage and voltage.

2.3 - Location

Storage

If the controller is to be stored for any length of time prior to

installation, the packing should be restored for protection

during that period. Where conditions permit, the packing

should be left intact until the controller is at the final installation

position. If the packing is removed, the top and openings

of the controller should be covered during the construction

period to protect it against dust and debris.

Indoor Equipment

Controllers designed for indoor installation (NEMA Type 1, 12)

which are not to be installed and energized immediately, should

be stored in a clean, dry space where a uniform temperature

prevents condensation. Preferably, the controller should be

stored in a heated building, with adequate air circulation and

protected from dirt and water. Equipment should be stored

where it is not subject to mechanical damage, especially during

building construction. An indoor controller that is to be stored

outdoors should be securely covered for protection from weather

conditions and dirt. Temporary electrical heating should be

installed to prevent condensation. Approximately 150 watts per

enclosure is usually adequate.

NOTE: All loose packing or flammable materials should be

removed before energizing space heaters.

Outdoor Equipment

An unenergized controller designed for outdoor installation (NEMA Type 3R, EPIC

building, etc.) should be kept dry internally by installing electrical heating or by energiz-

ing self-heaters, if provided. All openings, either used or unused should be covered or

sealed to prevent the entry of rain, vermin, insects, etc.
