Wiring the Main Circuit Output
Consider the following precautions for the output circuit wiring.
• Do not connect any other load than a 3 phase motor to the drives output.
• Never connect a power source to the drives output.
• Never short or ground the output terminals.
• Do not use phase correction capacitors.
• If using a contactor between the drive and motor, it should never be operated when the
drive is outputting a voltage. Operating while there is voltage output can cause large peak
currents, thus tripping the over current detection or damage the drive.
Ground Connection
Take the following precautions when grounding the drive:
• The drive must always be connected to ground in accordance to the general technical stan-
dards and local regulations.
As the leakage current produced by the drive exceeds 3.5 mA, according to IEC 61800-5-
1, at least one of the conditions below must be satisfied:
–The cross-section of the protective earthing conductor must be at least 10 mm
2
(Cu)
or 16 mm
2
(Al).
–The power supply must be disconnected automatically in case of discontinuity of
the protective earthing conductor.
• Keep ground wires as short as possible.
• Always make sure the ground impedance is conformed to the requirements of local safety
and installation regulations.
• Never share the ground wire with other devices such as welding machines, etc.
• Do not loop the ground wire when using more than one drive.
