2 - Installation

For a correct installation proceed as follows (Fig. 4):

￿Provide the unit with cornice protection elements (these can be supplied as optional), using the proper holes and the self-tapping screws with 3.5 mm diam￿ eter.

In order to avoid that water filters inside the contain￿ er, provide it with an adhesive rubber gasket.

￿Fix the cornice to the shelter wall by means of M4 screws with anchor.

￿Fix the lower cornice protection element by means of two M4 screws with anchor.

￿Provide the unit roof with the fixing bracket to the wall with two self-tapping screws with 3.5 mm diam￿ eter.

3 - Electrical and kit connections

Before performing any operations on the electric parts, make sure that:

￿all electrical components are undamaged;

￿all terminal screws are tight;

￿the supply voltage and frequency are as indicated on the unit;

￿the switch QS1 is in open position (OFF);

￿the automatic switch QS2 on the outer clamps of the inverter (if installed) are off;

￿there are no components under voltage.

3.1- Electrical connections (see the wiring diagram)

The electrical connections (power supply 230/1/50 and, for emergency power supply (48 and 24 Vdc) will be car￿ ried out from the roof of the unit by means of some pro￿ per holes.

￿Let the electrical power supply cable (not supplied by us), pass through the hole made on the unit roof.

Note: For the power supply use a screened cable (minimum section indicated in Tab. 4).

It is advisable to keep the mains power supply cable as far as possible from the other cables coming out of the inverter (optional).

Connect the 230V/1/50 Hz line to the main switch QS1 placed inside the electrical panel.

￿ Concerning the alarm contacts available in the differ￿ ent versions, these can be found on the terminal board in the electrical panel.

For the alarm description see Chapter 6 and the manual of the installed control.

￿ To connect 2 or more units installed in the same con￿ tainer and provided with the MICROFACE control, with HIROMATIC interface, use the HIROBUS cable (supplied with the unit) by connecting it as shown in the wiring diagram. See the Microface and Hiromatic manual for the configuration of the Stand-by units.
