Foreword
Relatively high leakage to earth occurs in the converter and the motor, i.e. the drive may be incompati-
ble with residual current protective devices. During operation, the principles on which the converter and
motor work, lead to leakage currents to earth which are dissipated via specified protective earth con-
nections and which may result in a current-operated e.l.c.b. on the input side blowing prematurely.
A DC component in the fault current may occur in the event of a short-circuit to frame or earth fault
which makes a triggering of the higher-level current-operated e.l.c.b. more difficult or even impossible.
The connection of the current controller to the mains using only the current-operated e.l.c.b. is
prohibited (EN 50178 / VDE 0160 /11.94, sections 5.2.11 and 5.3.2.1)
The units are protected against direct contact by being installed into common switching cabinets which
meet the minimum protection requirements according to EN 50178 / VDE 0160 / 4.98, section 5.2.4.
Sheets of plastic covering the control electronics, the power stage and the device connection,
additionally prevent accidental contact during commissioning and casual use of control elements
located close to the equipment (DIN VDE 0106 Part 100, Accident Prevention Regulation VBG4
”Electrical Systems and Equipment).
The protective measures and safety regulations according to DIN/VDE are binding for personal
security.
Neglecting to fit PE connections on the equipment or the motor will result in serious personal injury and/
or considerable damage to material assets.
It is only permitted to use the devices on earth-protected supply mains.
The discharge time of live parts is > 1 min. and depends on the connected DC link capacity.
This devices are not short-circuit-proof.
