3.7.2 Electrical components
Control cabinet, motor and control elements are protected as
standard at least to degree of protection IP 54. IP 54 means:
– Complete protection against contact with live components
or internal moving parts. Protection against damaging dust
deposits.
– Water spraying on the equipment from random directions
shall not have a damaging effect.
Use only original fuses with the specified current rating. The electrical
system can be destroyed by overrated fuses or bridging. You
must switch off the machine immediately if a fault occurs in the
power supply.
3.7.3 Power at the
construction site
The power on the construction site must be supplied from a special
feed point (construction site power distribution point). Machines
with an electric motor must not be connected to the mains power
supply.
Only qualified personnel may work on electrical systems with
an operating voltage in excess of 25 volts alternating voltage or
60 volts direct current. Only such qualified personnel may install,
connect, disconnect and open electrical control cabinets.
An electric shock (possibly with fatal consequences) may be the
result of touching machines with electric motors or contact with
other electrical cables if the electrical connection has not been
made properly or the supply cable is damaged.
