Safety Information
BUG 3/2/20 Basic Feed Unit 1
Baumüller Nürnberg GmbH 5.96064.02
1 SAFETY INFORMATION
Preliminary Remarks
During operation, the principles on which the power converter and the motor work lead to leakage
currents to earth that may be dissipated via the specified protective earths and may result in a current-
operated e.l.c.b. on the input side blowing prematurely.
In the case of a short-circuit to frame or to ground, a direct proportion may arise in the leakage current
that makes triggering a higher-level current-operated e.l.c.b. either more difficult or totally impossible.
This means that connecting the power converter 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 from direct contact by being installed in commercially available switching cabi-
nets that meet the minimum protection requirements of preliminary standard EN 50178/VDE
0160/11.94, Section 5.2.4.
Sheets of plastic covering the equipment connection act as additional guards preventing accidental
contact at commissioning and in the case of casual use of control elements located close to the
equipment (DIN VDE 0106 Part 100, Accident Prevention Regulation VBG4 "Electrical Systems and
Equipment").
At routine testing of this equipment, a high-voltage test is carried out that conforms with preliminary
standard EN 50178/VDE 0160/11.94, Section. 9.4.5.
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 property.
The equipment may only be run on grounded supply networks.
Sections carrying current take more than one minute to discharge.
The equipment is conditionally shortcircuit-proof.
