3.6.1 Introduction

This section describes how to connect the MAT air curtain to
the mains power supply.
Danger:
High voltages
Do not attempt to do this, unless you are qualified
to work with high-voltage power current.
At this stage, at least the air curtain unit(s) must be physically
installed in their final position.

3.6.2 Instructions

Connect the air curtain unit to the mains power supply by the
power cable 1 that is attached to the unit. If there are two air
curtain units, each unit is connected to the mains supply sepa-
rately.
When laying the connection, mind the following:
• The air curtain unit must be connected to a 3-phase 400 V
power source. Both the neutral and ground (earth) con-
nections are required.
• Each air curtain unit has a built-in 4-pole isolating
switch 2.
• Make sure that the power source and connections are able
to support the power consumption of the air curtain
unit(s).
• The connection must be done in compliance with the laws,
regulations, and standards that apply locally.
Warning:
Each air curtain unit must be earthed (grounded).
Warning:
Do this before you start:
• Put the isolating switch 2 in position "0" (off).
Do this for each air curtain unit, if there are two of them.
• Make sure that the mains supply group on which you are
working is switched off.
