Precautions
Wiring
²
Wiring must be performed by authorized and qualified
personnel. Risk of danger;
²
Circuit-breaker should be installed between inverter
and the mains. Risk of fire;
²
Make sure the input power supply has been completely
disconnected before wiring. Failure to comply may
result in personnel injury and/or equipment damage;
²
Since overall leakage current of this equipment may be
bigger than 3.5mA, for safety's sake, this equipment
and its associated motor must be well grounded so as
to avoid risk of electric shock;
²
Never connect the power cables to the output terminals
(U,V,W) of the AC drive. Pay attention to the marks of
the wiring terminals and ensure correct wiring. Failure
to comply will result in damage to the AC drive;
²
Install braking resistors at terminals (P+)and (P- or PB)
only. Failure to comply may result in equipment
damage.
²
Since all adjustable frequency AC drives from
Our
company
have been subjected to hi-pot test before
delivery, users are prohibited from implementing such a
test on this equipment. Failure to comply may result in
equipment damage.
²
Signal wires should to the best of the possibility be
away from main power lines. If this cannot be ensured,
vertical cross-arrangement shall be implemented,
otherwise interference noise to control signal may
occur.
²
If motor cables are longer than 100m, it is recommend-
ed output AC reactor be used. Failure to comply may
result in faults.
CAUTION
DANGER
²
Inverter shall be power-on only after the front cover is
assembled. Risk of electrical hazard.
DANGER
Before
Power-on
²
Verify that the input voltage is identical to the rated
voltage of product, correct wiring of input terminals R,
