11.10 AIR-COOLED CONDENSER POWER SUPPLY AND REGULATION CONNECTION (ACCESSORY)
Air-cooled condensers can be supplied with two types of electric power supply and regulation, as an accessory:
1) A 230 Vac power supply with cut-o regulation, dedicated to condensers with AC fans.
2) A 230 Vac or 400 Vac protected line (depending on the type of condenser) and a 0-10 Vdc signal line for the regulation of
condensers with EC fans.
When installing the unit, the power supply line of the air-cooled condensers must be set-up as shown in the gure below.
