3-6 Safety Instructions for Electric Drives and Controls ECODRIVE03-SGP-03VRS
DOK-ECODR3-SGP-03VRS**-WA01-EN-P
To be observed with electrical drive and filter components:
DANGER
High electrical voltage on the housing!
High leakage current! Danger to life, danger of
injury by electric shock!
Connect the electrical equipment, the housings of all
electrical units and motors permanently with the safety
conductor at the ground points before power is
switched on. Look at the connection diagram. This is
even necessary for brief tests.
Connect the safety conductor of the electrical equipment
always permanently and firmly to the supply mains.
Leakage current exceeds 3.5 mA in normal operation.
Use a copper conductor with at least 10 mm² cross
section over its entire course for this safety conductor
connection!
Prior to startups, even for brief tests, always connect the
protective conductor or connect with ground wire.
Otherwise, high voltages can occur on the housing
that lead to electric shock.
3.6 Protection Against Electric Shock by Protective Low
Voltage (PELV)
All connections and terminals with voltages between 0 and 50 Volts on
Rexroth Indramat products are protective low voltages designed in
accordance with international standards on electrical safety.
WARNING
High electrical voltage due to wrong
connections! Danger to life, bodily harm by
electric shock!
Only connect equipment, electrical components and
cables of the protective low voltage type (PELV =
Protective Extra Low Voltage) to all terminals and
clamps with voltages of 0 to 50 Volts.
Only electrical circuits may be connected which are safely
isolated against high voltage circuits. Safe isolation is
achieved, for example, with an isolating transformer,
an opto-electronic coupler or when battery-operated.
