JKSSS+ Series 2.3 - 4.2KV
There is a rating data label on the inside of each medium voltage compartment door.
Verify that the controller ratings properly match the system data by checking the follow-
ing:
1. Verify agreement of full load current, locked rotor current and acceleration time
with motor nameplate.
2. Verify that system voltage, number of phases and frequency matches controller
rating.
3. Verify that available short circuit current of power system is less than rated
short circuit capacity of controller.
Check connections - Although the equipment and devices have been completely tested
at the factory, a nal eld check should be made that all electrical wiring and bus bar
connections are correct and have not become loose in transportation. Refer to MAINTE-
NANCE Section for electrical joint specication.
All blocks or other temporary braces used for shipment must be removed.
Before closing the enclosure, all metal chips, scrap wire and other debris left over from
installation must be cleaned out.
If there is an appreciable accumulation of dust or dirt, the enclosure should be cleaned
by using a brush, vacuum cleaner or clean, lint free brush.
The integrity of all bus bar supports must be checked for secureness and damage.
Care should be exercised that when covers are installed and doors closed, no wires are
pinched and that all enclosure parts are properly aligned and tightened.
A supply of spare parts, fuses, etc. should be established.
Instruction manuals and diagrams should be collected and led.
Field wiring should be checked for clearance to live busses where necessary, physically
secured to withstand the effects of fault current.
All grounding connections should be checked.
Each motor should be connected to its intended controller, and phase rotation should be
correct prior to startup.
Changes made to circuit diagrams during installation should be recorded.
All devices should be checked for damage. All necessary repairs or replacements should
be made.
