WIRING
Before changing the equipment connections, shut off the inverter and wait at
least 5 minutes to allow for the discharge of the capacitors in the DC-link.
DANGER
Use only B-type differential circuit breakers.
Connect the power supply line to supply terminals only. The connection of the
power supply line to any other terminal will damage the inverter.
Always make sure that the supply voltage ranges between the limits stated in the
inverter nameplate.
Always connect the ground terminal to avoid electrical shock hazard and to limit
disturbance.
The user has the responsibility to provide a grounding system in compliance with
the regulations in force.
After connecting the equipment, check the following:
-
all wires are properly connected;
-
no link is missing;
-
no short-circuit is occurring between the terminals and between the
terminals and the ground.
Do not start or stop the inverter using a contactor installed over the inverter
power supply line.
The inverter power supply must always be protected by fast fuses or by a
thermal/magnetic circuit breaker.
Do not apply single-phase voltage.
Always mount antidisturbance filters on the contactor coils and the solenoid valve
coils.
CAUTION
At power on, if the inverter commands “ENABLE ” (terminal 6) and “START”
(terminal 7) are active, the motor will immediately start when the main reference
is other than zero. This may be very dangerous. To avoid accidental starting of
the connected motor, set parameter C61 (IFD SW) or C53 (VTC SW) to [NO]. In
that case, the motor will start only after opening and closing the command
contact on terminal 6.
