Safety Instructions for Electric Drives and Controls
2-5
DOK-RD500*-RS51*******-IB02-EN-P
To be observed for electric drives and filter components:
DANGER
High voltage! High leakage current! Danger to
life, danger of injury and bodily harm from elec-
trical shock!
Before powering-up all housings and motors must be
permanently grounded according to the connection
diagram. This applies even for brief tests.
The protective conductor of the electrical equipment
must be permanently connected to the line supply.
The leakage current is greater than 3.5 mA.
Use a copper conductor with at least 10 mm² cross
section over its entire course for this protective con-
nection!
Prior to start-ups, even for brief tests, always con-
nect the protective conductor or connect with ground
wire. High voltage levels can occur on the housing
that could lead to severe electrical shock and per-
sonal injury.
European countries: EN 50178 / 1998, Section 5.3.2.1.
US: Refer to the National Electrical Code (NEC), National
Electrical Manufacturers Association (NEMA), and local
building codes. The user of this equipment must observe
the above noted instructions at all times.
2.6
Protection against electrical shock by protective low
voltage (PELV)
All connections and terminals with voltages between 5 and 50 Volts on
Indramat Refu products are protective low voltages designed in accor-
dance with the following Standards:
•
International: IEC 60364-4-41
•
EU countries: Refer to EN 50178/1998, Section 5.2.8.1.
WARNING
High voltage due to wrong connections! Danger
to life, severe electrical shock and severe bodily
injury!
Only equipment, electrical components and cables of
the protective low voltage type (PELV = Protective
Extra Low Voltage) may be connected to all termi-
nals and connections with 0 to 50 Volts.
Only safely isolated voltages and electrical circuits
may be connected. Safe isolation is achieved, for
example, with an isolating transformer, a safe opto-
electronic coupler or when battery-operated.
