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”.

B - INSTALLATION

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).
