Connecting
7.8 Connecting the power supply
Connecting the mains lines
Warning
!
Before connecting the modules, first disconnect the equipment from the mains!
For connecting the power supply, use flexible lines with a line cross-section of at least
1 mm
If you only connect one line per connection, end sleeves are not absolutely necessary.
If you connect several lines per connection, you should use end sleeves.
Remove the isolation from the cable end, fit an end sleeve if necessary, insert the cable end
(with end sleeve) into the screw-terminal connection and tighten the fastening screw.
Insert the screw terminal with the cables to connection X40 on the CNC operator panel.
Polarity reversal protection
With correct connection and the power supply turned on, the LEDs "RDY" (PCU) and
"POWER" (PP72/48) are lit in green.
Note
In case of polarity reversal, the control system will not work. However, a built-in reverse
polarity protection facility protects the electronics against damage.
Fuse
In case of a defect in the control system, an internally installed fuse protects the electronics
from collateral damage (e.g. fire). In this case, the entire control system must be replaced.
