19.4.  ELECTRICAL CONNECTION OF THE HVAC UNIT

Electrical connection can only be implemented by the qualified electrician in accordance with the applicable international and national electrical 

safety requirements and requirements for installation of electrical devices.

Use only power source which meets the requirements specified on the device label.

Power supply cable should be selected based on the electrical specification of the device. If the device power supply line is far from the unit, the 

distance and voltage drop should be considered.

Device must be earthed.

Install the control panel at the designated place.

Install the supplied connection cable(FLEX controller) between the control panel and the HVAC unit. It is recommended to install the control panel 

separately from the power cables.

Note:

 If cable is used together with other power cables, shielded control panel cable with earthed shield should be used.

Connect the plug (RJ10 type) to the RS485-1 socket of the unit. Connect the other end to the control panel.

RS458_1 RS458_2

NOTE:

 The remote control panel can be connected and (or) disconnected only after disconnecting the power supply for the HVAC unit.

Switch on the mains voltage, switch on the blade switch Q, see 

Fig. 5

 (actual appearance of the blade switch can be different from the given photo 

based on the model of the product).
