Protection Against Contact with Electrical Parts and Housings
DANGER
Rexroth IndraMotion MTX 09VRS | Application Description
and Controls
Risk of injury by improper handling of batteries!
Observe the safety instructions!
This section concerns devices and drive components with voltages
of more than 50 Volt.
Contact with parts conducting voltages above 50 Volts can cause personal
danger and electric shock. When operating electrical equipment, it is unavoid‐
able that some parts of the devices conduct dangerous voltage.
High electrical voltage! Danger to life, electric shock and severe bodily
injury!
●
Only those trained and qualified to work with or on electrical equipment
are permitted to operate, maintain and repair this equipment.
●
Follow general construction and safety regulations when working on pow‐
er installations.
●
Before switching on the device, the equipment grounding conductor must
have been non-detachably connected to all electrical equipment in ac‐
cordance with the connection diagram.
●
Do not operate electrical equipment at any time, even for brief measure‐
ments 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 electric 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. Do not remove or plug in connectors when the component
has been powered.
●
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.
