Electrical connection

When carrying out any work on the machine, observe the general safety instructions
(Page 77) and the specifications contained in EN 50110-1 regarding safe operation
of electrical equipment.
6.1

Connecting the machine

DANGER
Hazardous voltages
Death, injury or material damage can occur. Note the following safety
information before connecting-up the machine:
Only qualified and trained personnel should carry out work on the
•
machine while it is stationary.
Disconnect the machine from the power supply and take measures to
•
prevent it being reconnected. This also applies to auxiliary circuits.
Check that the machine really is in a no-voltage condition.
•
Establish a safe protective conductor connection before starting any
•
work.
If the incoming power supply system displays any deviations from the
•
rated values in terms of voltage, frequency, curve form or symmetry,
such deviations will increase the temperature and influence
electromagnetic compatibility.
Operating the machine on a line supply system with a non-grounded
•
neutral point is only permitted over short time intervals that occur
rarely, e.g. the time leading to a fault being eliminated (ground fault of
a cable, EN 60034-1).
All cable glands and blanking plugs must be implemented according to Directive
94/9/EC up to April 19, 2016 - or from April 20, 2016, Directive 2014/34/EU. They
must also be certified for use in hazardous zones.
● Any openings that are not being used must be sealed using the appropriate
certified blanking plugs.
● Please observe the manufacturer's specifications when fitting cable glands.
