FLUXMASTER 50 INSTRUCTION MANUAL
External wiring should be carried out in accordance with the following requirement.Check and reassure the wiring is correct
after completion.
(Do not utilize the control circuitry buzzer to check the wiring).
EMI Connections:
It is very important that the connections between the AC drive, the shielded motor cable, and the EMI filters are tested as follows.
❙ Use a metal grounding plate and place the AC drive and the EMI filter on the plate.
❙ Use a shielded motor cable with 4 connectors (U,V, W, & Earth).Don't use the shielding as safety earth (shield is high
frequency earth).
❙ Remove any paint around the two metal coupling nut holes to ensure that the metal coupling nuts (and the shielding) make
contact with the AC drive and the motor.
❙ Don't solder a conductor to the shielding.
❙ Use a metal clamp to connect the shielding from the motor cable with the metal grounding plate.This ensures a perfect
high frequency earth connection between AC drive, grounding plate and EMI filter.
❙ Keep the distance between the AC drive and EMI filter as short as possible (< 11.8"). If longer, use a shielded cable with a
metal coupling nut and a metal clamp to connect the shielded cable to the AC drive and metal grounding plate.
❙ The only earth connection between the LISN and the test plate should be via the EMI filter.
❙ Use a motor rated at or below the AC drive rating.
❙ Install a noise filter for AC drive on the output side of the primary circuit to suppress conducting noise.
