Special safety instructions
Caution!
Due to movable machine parts and high voltages, the device can pose a lethal
danger. Danger of electric shock in the case of non-respect of the following
instructions. The device corresponds to DIN EN 61800-3, i.e. it is subject to limited
sale. The device can emit disturbances in certain local environments. In this case,
the user is liable to take suitable measures.
Check that all live terminals are secured against contact. Perilous voltage levels of
up to 850V occur.
Do not bypass power direct current
Caution!
Due to movable machine parts and high voltages, the device can pose a lethal
danger. Danger of electric shock in the case of non-respect of the following
instructions. The device corresponds to DIN EN 61800-3, i.e. it is subject to limited
sale. The device can emit disturbances in certain local environments. In this case,
the user is liable to take suitable measures.
The device must be permanently grounded due to high earth leakage currents.
The drive motor must be grounded with a suitable protective lead.
The devices are equipped with high voltage DC condensers. Before removing the
protective cover, the discharging time must be awaited. After switching off the
supply voltage, it may take up to 10 minutes (with additional capacity modules it
may take up to 30 minutes) to discharge the capacitors.
Danger of electric shock in case of non respect.
Before you can work on the device, the supply voltage must be switched off at the
L1, L2 and L3 clamps. Wait at least 10 minutes so that the power direct current
may sink to a secure value (<50V). Check with the aid of a voltmeter, if the voltage
at the DC+ and DC- clamps has fallen to a value below 50V.
Danger of electric shock in case of non respect.
Do never perform resistance tests with elevated voltages (over 690V) on the wiring
without separating the circuit to be tested from the drive.
Please exchange devices only in currentless state and, in an axis system, only in a
defined original state.
If the axis controller is replaced, it is absolutely necessary to transfer the
configuration determining the correct operation of the drive to the device, before
the device is put into operation. Depending on the operation mode, a machine zero
run will be necessary.
The device contains electrostatically sensitive components. Please heed the
electrostatic protection measures while working at/with the device as well as during
installation and maintenance.
Operation of the PSUP30 only with line choke.
Attention - hot surface!
The heat dissipater can reach very high temperatures (>70°C)
Protective seals
Caution!
The user is responsible for protective covers and/or additional safety measures in
order to prevent damages to persons and electric accidents.
