5.1. Mains and welding transformer connection
1070 078 131-104 (00.05) GB
Power Supply Module
WARNING!
-
The mains voltage is associated with many dangers!
!
The possible consequences of inappropriate handling include death or most se-
vere injuries (personal injuries) and damage to property.
For this reason, the electrical connection must always be made by an electrical
expert in compliance with the valid safety regulations, the mains voltage and the
maximum current consumption of the individual units of the equipment.
The mains voltage must be identical with the nominal voltage given on the
nameplate of the product!
Appropriate electrical fusing equipment must be available on the mains side!
-
Danger of life through electrical voltage!
Changing the system voltage of the power supply module (cf. "Mains voltage
selection" section), if necessary, may only be performed when the system is de-
energized. In any case, suitable insulated tools should be used for this purpose.
-
Danger of life through electrical voltage!
The power supply modules must be connected to the protective earthing (PE)
circuit of the system. Please ensure that a sufficient conductor cross-section is
used for wiring the protective conductor. The electrical continuity of the protec-
tive earthing circuit must be verified in accordance with EN 60204 Part 1.
CAUTION!
-
The following must be noted before making the connection:
!
-
mains OFF
-
protection against reclosing
-
verify safe isolation from supply
-
earthing and short-circuiting
-
cover or barrier adjacent live parts
-
Mains voltage variations or deviations from the rated value must be within the
specified tolerance limits (cf. "Technical data" section). Otherwise, failures
and/or dangerous situations at the electrical components cannot be entirely
ruled out.
