Special safety instructions
Check the correct association of the device and its documentation.
Never detach electrical connections while voltage is applied to them.
Safety devices must be provided to prevent human contact with moving or
rotating parts.
Make sure that the device is operated only when it is in perfect condition.
Implement and activate the stipulated safety functions and devices.
Operate the device only with the housing closed.
Make sure that all axes are sufficiently fixed.
Attention during configuration downloads with master - slave couplings (electronic
gear, cam)
Deactivate the drive before starting the configuration download: Master and Slave
axis
Check that all live terminals are secured against contact. Fatal voltage levels of to
850V occur.
Do not bypass power direct current
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
energy, it may take up to 5 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 3 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 (not possible
on the Compax3M).
Do never perform resistance tests with elevated voltages (over 690V) on the
wiring without separating the circuit to be tested from the drive.
In the event of a device exchange 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.
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.
Attention hot surface!
The heat dissipator can reach very high temperatures (>70°C)
Protective covers
The user is responsible for protective covers and/or additional safety measures in
order to prevent damages to persons and electric accidents.
