2. INSTALLATION

Do not connect the equipment to the mains before the installation is complete.

Do not attempt to move or hang the equipment mechanically (e.g. with a hoist) from the handle on the power

source unit. The handle is meant only for manual lifting.

Place the machine on a horizontal, stable and clean ground. Protect the machine from rain and direct sunshine.

Check that there is enough space for cooling air circulation in the machine vicinity.

Before installation

•Make sure to acknowledge and follow the local and national requirements regarding installation and use of high

voltage units.

•Check the contents of the packages and make sure the parts are not damaged.

•Before you install the power source on site, see the requirements for the mains cable type and fuse rating given in

the "Technical data" on page64 chapter.

Do not connect the machine to the mains before the installation is complete.

Only an authorized electrician is allowed to install the mains cable.

Distribution network

MasterTig 235ACDC: This equipment complies with IEC 61000-3-12 and can be connected to public low-voltage sys-

tems.

MasterTig 325DC and 335ACDC: Provided that the public low voltage short circuit power at the point of common

coupling is higher than or equal to the value stated on the list below, this equipment is compliant with IEC 61000-3-

11 and IEC 61000-3-12 and can be connected to public low voltage systems. It is the responsibility of the installer or

user of the equipment to ensure, by consultation with the distribution network operator if necessary, that the system

impedance complies with the impedance restrictions.

•MasterTig 325DC and 335ACDC: 1.7 MVA

•MasterTig 325DC G and 335ACDC G: 1.9 MVA

•MasterTig 325DC GM and 335ACDC GM: 1.4 MVA

•MasterTig 425DC G: 2.0 MVA

According to the EMC classification (Class A), the MasterTig 235, 325, 335 and 425 equipments are not intended to be

used in residential locations where the electrical power is provided by the public low-voltage supply system.

2.2 Installing control panel

Tools:

•Screwdriver, Torx head (T20).

1. Connect the control panel’s cable and mount the control panel in place:

>> Insert the top of the panel in the slot first, and then lower the bottom of the panel down.

>> Push the bottom of the panel firmly so that it locks in place.

2. Secure the control panel together with the hinged panel cover in place with the screw provided.

The hinged panel cover and the control panel are secured with the same screw.

2.3 Installing cooling unit

Only an authorized electrician is allowed to install the cooling unit.

Do not connect the equipment to the mains before the installation is complete.

Do not attempt to move the power source with a hoist from its handle. The handle is meant for manual lifting only.

When a transport cart is used, refer also to "Mounting units on cart (optional)" on page13.

Tools:

•Screwdriver, Torx head (T20).

1. Remove the power source's rear cover.

2. Move the power source on top of the cooling unit so that the bar in the rear goes into the rear connection interface

and lower the front onto the front connection interface. Secure the power source from the front with the screws

provided.

Ensure that the cooling unit’s connection cables don't get caught between the units and get damaged in the process.
