3-6 Safety Instructions for Electric Drives and Controls Rexroth IndraDrive
DOK-INDRV*-FU*********-IB01-EN-P
section 5.3.2.3.
USA: See National Electrical Code (NEC), National
Electrical Manufacturers' Association (NEMA), as well as
local engineering regulations. The operator must observe
all the above regulations at any time.
With electrical drive and filter components, observe the following:
DANGER
High housing voltage and large leakage current!
Risk of death or bodily injury by electric shock!
Before switching on, the housings of all electrical
equipment and motors must be connected or
grounded with the equipment grounding conductor to
the grounding points. This is also applicable before
short tests.
The equipment grounding conductor of the electrical
equipment and the units must be non-detachably
and permanently connected to the power supply unit
at all times. The leakage current is greater than
3.5 mA.
Over the total length, use copper wire of a cross
section of a minimum of 10 mm
2
for this equipment
grounding connection!
Before start-up, also in trial runs, always attach the
equipment grounding conductor or connect with the
ground wire. Otherwise, high voltages may occur at
the housing causing electric shock.
Protection Against Electric Shock by Protective Low Voltage (PELV)
All connections and terminals with voltages between 5 and 50 Volt at
Rexroth products are protective extra-low voltage systems which are
provided with touch guard according to the product standards.
WARNING
High electric voltage by incorrect connection!
Risk of death or bodily injury by electric shock!
To all connections and terminals with voltages
between 0 and 50 Volt, only devices, electrical
components, and conductors may be connected
which are equipped with a PELV (Protective Extra-
Low Voltage) system.
Connect only voltages and circuits which are safely
isolated from dangerous voltages. Safe isolation is
achieved for example by isolating transformers, safe
optocouplers or battery operation without mains
connection.
