9
CAUTION
Separate the control cables from the power cables as much as possible.
Keep the connecting cables away from rotating mechanical parts.
Commissioning
WARNING
The following terminals can carry dangerous voltages even if the inverter is not operating:
- The mains input terminals L1, L2, L3, and PE
- The motor terminals U, V, W, and output earth terminal
- The DC link terminals DC+ and DC-
- The braking resistor terminals R1 and R2 (Frame size D only)
This equipment must not be used as an "emergency stop" mechanism (
see EN 60204,
9.2.5.4).
It is not allowed to open, connect or disconnect the equipment during its operation.
Operation
WARNING
Certain parameter settings may cause the inverter to restart automatically after an input
power failure, for example, the automatic restart function.
Motor parameters must be accurately configured for motor overload protection to operate
correctly.
Use of mobile radio devices (e.g. telephones, walkie-talkies) in the immediate vicinity of the
devices (< 1.8 m) can interfere with the functioning of the equipment.
Risk of fire
If an unsuitable braking resistor is used, this could result in a fire and severely damage,
people, property and equipment. Use the adequate braking resistor and install it correctly.
The temperature of a braking resistor increases significantly during operation. Avoid coming
into direct contact with braking resistors.
WARNING
During operation and for a short time after switching off the inverter, the marked surfaces of
the inverter can reach a high temperature. Avoid coming into direct contact with these
surfaces.
