Electrical connections

General

• The acceptable voltage variation is: ± 10% during operation.

• The electrical connection conduits must be fixed.

• Class 1 unit.

Power supply

• The power supply must come from an isolation and electric protection device (not supplied) in accordance with existing

regulations.

• The installation must be protected by a double-pole circuit-breaker (not included).

Connect the power input to the L/N connection block and the ground to the chassis ground connection.

Connect the Electrical Heaters of the external tank to the proper connection block; Emix supports up to three Electrical

elements of 1500 W each one; for connections to three-phase tanks, use R1,R2 and R3 as the command of an elec-

trical panel with circuit breakers. Electrical heaters supporting Emix operation in case of heat pump trouble, very low

outdoor temperature and some time during the legionella cycle; we suggest to connect at least one electrical element.

Note 1: when Emix is connected in a single split con guration to the normal indoor port, you have to take care about

the proper Gas/Liquid connection and you have to remove JP1 on the main board of Emix; if you don’t respect this

indications, the unit will have bad performance, trouble and out of order conditions.

Note 2: Emix electrical consumption is very low but in case electrical heater elements are connected, Emix has to

support the  ow of big amount of electrical energy; for that reason it is necessary to power Emix independently to the

power supplied by the outdoor unit.

Connect the communication shielded pair cable (24

AWG) to the connection block C1 and C2 and the

shield to the communication ground connection; take

care about polarity between outdoor unit and Emix; in

case of mistake you will see a communication error in-

dication (all the LED  ashing).

Connection block IN1/IN2 are factory closed; they can

be used in case of external timer, external solar control

box or any dry contact used to enable or disable Emix

unit.
