4.3 Connections
Mains connection
The control cabinet is supplied as standard with cable glands for the entry of
incoming supply cables. The mains voltage is connected to the control cabinet’s
main power switch as set out in the wiring diagram.
The main connection must be carried out by qualified personnel.
Also refer to the Product Manual for the robot.
In welding cells type FlexArc and FlexArc Compact the mains cable is routed to a
63A IEC-socket, located on the wall of the cell, for easy mains connection.
Information on the mains voltage, fuse protection, etc can be found in section 3
“Technical data”.
4.4 Start up
Check that all component equipment is connected correctly.
Switch on the main power switch on the control cabinet and the main power switch
on the welding power source if fitted. The main power switch on the control
cabinet normally controls the power supply to all component modules in the
cabinet.
Note! Some welding power sources provide the process control card with
external reference voltage, which is why parts of the control cabinet can be
energised even when the main power switch is in the “OFF” position.
All requisite system software is installed on delivery.
Wait until the message “Welcome to….” is shown on the programming unit’s
display.
