Wiring Checks
Using Figure 5-3: Basic Schematic Diagram (p24) , visually check the wired components to confirm,
verify, and correct wiring. Then, with a multimeter, check phase to phase isolation using the 100 K
ohm range. The multimeter will read the parallel equivalent of the bleeder resistors after the
capacitors initially charge. All phase to phase resistance values should be the same.
Check for the Following Faults:
• Capacitor shorted
• Capacitor bus not connected
•
Capacitor bus to chassis short
•
Parallel wiring errors
Torque Ratings Tables
Please see Table 5-2: Torque Ratings 380-480V (p27) and Table 5-3: Torque Ratings 600V (p28)
for torque ratings.
NOTE: Cap-panel interconnect wiring specification according to UL508 75° C Table.
NOTE: To prevent flexing or bending of the coil windings attached to SWN reactor use
appropriate strain relief to prevent stress on terminals. For flat copper terminal tabs, use two
wrenches to tighten customer provided cable mounting hardware.
NOTE: Refer to reference drawings for termination wire ranges.
