This power source is a power supply where the intensity is imposed at all times. The
system stability relies on an electronic current regulation system that can react at the speed
of the arc.
It is cooled by a forced ventilation system. Filters placed on the air inlets extend the life of
the components of the power source when it is used in dusty environments.
The cooling air is taken in through openings in the side panels and the upper front door
and then transferred to the rear by means of a fan.
NERTAMATIC 450 has several auxiliary power supply systems, which are alternative low-
voltage sources that power the cycle box, the AVC, the wire feeding funcion, the BRT, some
movements etc.
It offers an internal visualisation of its operating status and a galvanised insulated interface
for dialogue with the “outside”.

1 - UNPACKING - HANDLING
1) Unpacking
2) Handling
Cut the box straps.
You can now install the power supply either :
Remove the cover plate and protective cover
(cardboard).
- with a fork lift truck or a pallet truck,
Disunite the power supply from the pallet (8 mm
nuts).
- or using the 2 slinging rings intended for that
purpose with a crane or a lifting bridge.

3) Location of the current source (power source):
For optimised operation and a longer life, the
power source location should be selected
carefully. The device should not be installed in
places exposed to humidity, high temperature
or corrosive fumes. Leave clearance of 500
mm around the sides and rear of the unit.
Make sure that the fan openings are not
blocked. Air enters into the machine through
the front and the sides.

2 - CONNECTION
The installation is wired for a 400V mains
voltage.
If the power supply voltage is 230V,
415V or 440V, the transformers inside
the power source must be rewired
accordingly.
Primary cable
Primary + auxiliary wiring
CONNECTING NERTAMATIC 450
Remove the right side panel (10 mm key).
Wire the main transformer and the auxiliaries by means of terminal plates
PAB1, PAB2 and PAB3, depending on the local supply voltage.
DO NOT FORGET THE AUXILIARY WIRING (PAB3).
Connect the power supply cable to the terminal plate (right-hand side of
the contactor).
