Connecting electric power
Installation may only be done by authorized personnel.
Connect electric power to the machine as follows:
Connect the power supply to the electrical connections of the machine; see the dia
-
gram with alternative connection arrangements.
For easier servicing and maintenance, the supply to the machine should be fitted
with a lockable isolator with a 3 mm break gap.
The isolator must be located in an easily accessible position on the wall.
The supply cable must be brought in through a hole in the side, fitted with a rubber
seal. The side has two holes, one on the left and one on the right.
Remove the Plexiglas cover over the incoming side of the terminal block. Refit the
Plexiglas cover when the connections have been made.
The supply cable and any signal cables must be provided with strain relief by
means of the cable glands at the bottom of the electrical cabinet.
The power supply cable to the machine must be connected to the incoming terminal strip
-X01. The protective ground (earth) wire must be connected to the terminal marked with
the protective ground (earth) symbol in terminal strip –X01.
Smallest cable area for power supply.
Steam.
Incoming terminal strip –X01 can take cables with conductor area between
AWG16-8 (1.5 – 10 mm
2
).
The area of the supply cable must not be less than AWG 10 (6 mm
2
). Its diameter must
not be less than Ø 18 mm.
Electrical
Incoming terminal strip –X01 can take cables with conductor area between
AWG16-8 (1.5 – 10 mm
2
).
The area of the supply cable must not be less than AWG 8 (10 mm
2
). Its diameter must
not be less than Ø 21 mm.
Residual current device (RCD)
The machine is fitted with a frequency converter to control the rotation speed of the
circulation pump. If there is an RCD in the power supply line to the machine, the RCD
must be designed to protect equipment with a frequency converter.
