Before switching on the device, the equipment grounding conductor must have been no
detachably connected to all electrical equipment in accordance with the connection diagram.
»
Do not operate electrical equipment at any time, even for brief measurements or tests, if the
equipment grounding conductor is not permanently connected to the mounting points of the
components provided for this purpose.
»
Before working with electrical parts with voltage potentials higher than 50 V, the device must
be disconnected from the mains voltage or power supply unit. Provide a safeguard 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 protective 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 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 PMC products are
protective extra-low voltage systems which are provided with touch guard according to the
product standards.
