to prevent reconnection.
» With electrical drive and filter components, observe the following:
Wait 30 minutes after switching off power to allow capacitors to discharge before
beginning to work. Measure the voltage on the capacitors before beginning to work to
make sure that the equipment is safe to touch.
» Never touch the electrical connection points of a component while power is turned on.
» Install the covers and guards provided with the equipment properly before switching the
device on. Before switching the equipment on, cover and safeguard live parts safely to
prevent contact with those parts.
»
A residual-current-operated circuit-breaker or r.c.d. cannot be used for electric drives!
Indirect contact must be prevented by other means, for example, by an overcurrent pro-
tective device according to the relevant standards.
»
Secure built-in devices from direct touching of electrical parts by providing an external
housing, for example a control cabinet.
With electrical drive and filter components, observe the following:
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 con-
nected 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 mm2 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 PMC products are
protective extra-low voltage systems which are provided with touch guard according to the
product standards.
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, elec-
trical 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.
Protection Against Dangerous Movements
Dangerous movements can be caused by faulty control of connected motors. Some common
examples are:
