SECTION 4 ELECTRICAL INSTALLER
This section explains the procedures to follow for the correct electrical hook-up of the
ACF60-00, and also gives the wiring diagrams which may be useful for any maintenance
interventions.
The electrical connections must be done by a Qualified Service Engineer in
conformance with EU regulations and in accordance with local norms and
regulations.
An incorrect installation or an installation that is not compliant with the regulations
of the law could cause harm to people, animals and objects; Robur S.p.A. is not
responsible to damages relating to incorrect installation or installation that does not
conform to the regulations of the law.
Operational control of the ACF can be done in one of the following ways:
1. By means of an ON/OFF control switch. The control switch could be an ON-OFF
switch, an ambient thermostat, programming clock, etc.
2. By means of the Direct Digital Controller (DDC) available as an accessory
(see”ACCESSORIES” on page 81).
The wiring diagrams for ACF60-00 connection can be found in paragraph 4.3
PUMP AND ELECTRICAL WIRING DIAGRAMS on page 56.
The wiring diagrams for HR circulator pump connection can be found “Heat recovery
circulator pump control (only for HR model))” on page 55.
If you would like to hook up a DDC to the ACF60-00, see also the wiring diagrams in
paragraph USE OF A DIRECT DIGITAL CONTROLLER (DDC) on page60.
4.1 OPERATION WITH CONTROL SWITCH
Before making any electrical connections, make sure that there are no live parts.
General instructions
Check that the power supply is 230 V 1N 50 Hz.
Perform the electrical hook-ups following the wiring diagrams seen in Figure 19 and
Figure 20 on page 56 as well as Figure 24 on page 60.
Make the electrical connections so that the ground cable is longer than the power cables.
It should be the last cable to disconnect if the power cable is accidentally pulled out,
ensuring ground connection.
The electrical safety of the appliance can only be guaranteed when it is correctly
connected to a proper ground, done in conformance with current safety regulations.
Do not use the gas tubes as a ground for electrical appliances.
