WARNING
No function of the external shut-down devices (emergency stop switch)!
If the emergency stop circuit has been realised using an external shut-down device via
the interface for mechanised welding, the device must be set for this setup. If this is not
observed, the power source will ignore the external shut-down devices and will not shut
down!
• Disconnect jumper 1 on PCB T320/1 (Tetrix) or M320/1 (Phoenix / alpha Q)!
CAUTION
Equipment damage due to unshielded control leads!
Unshielded control leads can cause damage to the power source and accessory
components.
• Use shielded control leads only.
The welding power sources feature a very high safety standard.
This safety standard is also maintained when peripheral equipment is connected for mechanised welding,
if this peripheral equipment meets the same criteria, particularly with regard to isolation from the mains
supply.
This is guaranteed by the use of transformers conforming to VDE 0551.
The welding machines are equipped for mechanised operation as standard.
For the simplest possible mechanised applications, control inputs and galvanically isolated relay contacts
are available on the interface for mechanised welding.
