Final Test Procedures
Final Test Procedures
• Verify that the enclosure is properly grounded.
•
Verify that phase-to-phase and phase-to-ground clearances meet
the requirements of the local electrical code.
•
Visually check for sufficient electrical clearances, creepage
allowances and bend radii. Refer to the applicable local electrical
codes.
•
Check the tightness of all power and control connections. Refer to
Table 8.A for recommended torque values. Gently tug on all wires
to ensure that they are properly connected.
Table 8.A – Recommended Torque Values
Hardware Recommended Torque
1/4 in. 6 ft·lb (8 N·m)
5/16 in. 11 ft·lb (15 N·m)
3/8 in. 20 ft·lb (27 N·m)
1/2 in. 48 ft·lb (65 N·m)
Control Wire Terminals 3 in·lb (0.3 N·m)
CLGD Power Assembly Terminals 50 in·lb (5.6 N·m)
SMC Flex Control Module Terminals 5 in·lb (0.6 N·m)
A T T E N T I O N A T T E N T I O N All hardware for electrical connections must be
torqued to the above specifications. Failure to do
so may result in electrical faults causing
personal injury or damage to the equipment.
• Check for cross-threaded hardware. In addition to the regular
power connections, check the connections and wiring to the
voltage sensing board.
• The high voltage silicone-insulated wires must be identified with
tube markers. Avoid routing the wires over any components. If the
wires are routed across two heatsinks, there must be enough slack
in the wire to allow at least 10 centimeters (four inches) of creepage
between the heatsinks. Tie wraps must not tightly squeeze the high
voltage wires, and must not be put on with a tie-wrap gun.
