ECODRIVE03 SMT-02VRS Safety Instructions for Electric Servo Drives and Controls 2-5
DOK-ECODR3-SMT-02VRS**-WA01-EN-P
To be observed with electrical drives, power supplies, and filter
components:
DANGER
High electrical voltage ! High leakage current !
Danger to life, danger of injury and bodily harm
from electrical shock !
⇒
Before switching on power for electrical units, all
housings and motors must be permanently grounded
according to the connection diagram. This applies
even for brief tests.
⇒
Leakage current exceeds 3.5 mA. Therefore the
electrical equipment and units must always be firmly
connected to the supply network.
⇒
Use a copper conductor with at least 10 mm² cross
section over its entire course for this protective
connection !
⇒
Prior to startups, even for brief tests, always connect
the protective conductor or connect with ground wire.
High voltage levels can occur on the housing that
could lead to severe electrical shock and personal
injury.
European countries: EN 50178/1998, section 5.3.2.1.
USA: See National Electrical Codes (NEC), National
Electrical Manufacturers Association (NEMA), and local
building codes. The user of this equipment must maintain
the above noted instructions at all times.
2.6 Protection by protective low voltage (PELV) against
electrical shock
All connections and terminals with voltages between 5 and 50 Volts on
INDRAMAT products are protective low voltages designed in accordance
with the following standards on contact safety :
•
International: IEC 364-4-411.1.5
•
EU countries: see EN 50178/1998, section 5.2.8.1.
WARNING
High electrical 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
terminals and clamps 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, an opto-
electronic coupler or when battery-operated.
