Introductory remarks
During operation, the principles on which the converter and motor work, lead to leakage currents to earth
which are dissipated via specified protective earth connections and which may result in a current-oper-
ated 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
(preliminary standard 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 pr EN 50178 / VDE 0160 / 11.94, section 5.2.4.
Sheets of plastic covering the control electronics, the power stage and the device connection, addition-
ally 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 units on earth-protected supply mains.
The discharge time of live parts is > 1 min.
The units are partly short-circuit-proof.
