For voltage unbalance;
Voltage balance =100A/2Vort
For example, if the measured voltages are 221.230 and 227, the average voltage will be 226V.
A=(226-221)+(230-226)+(227-226)
The electrical connections of the air handling unit are carried out of the device
with materials such as junction boxes, coupling, etc. Unless there is special instruction, holes, slots, etc. should not
be drilled into the air handling unit. Otherwise, it may adversely affect the operating performance of the device.
Ensure that the grounding circuit is suitable for its function.
The cross-section of the supply cables should be determined by taking into
account the voltage drops depending on the distance.
In case of short circuit, overload or double phase, it is recommended to put a
thermal phase protection relay, fuse, etc. in the electrical circuit.
Make sure that the main power supply character meets the EN 60204-1 regulation.

Control Panel and BMS Connection
Air handling units that are requested with automation equipment can be integrated with the building automation sys-
tem via Modbus TCP-IP / Bacnet protocols and can be monitored with these protocols. Ethernet (RJ45) port on the
controller located in the unit automation panel should be used for BMS connection.
Terminals are reserved on the automation panel
for external display connections (E3-DSP/ED-T7).
Screen connections must be made with 4x0.50
shielded cable. The maximum wiring distance for
touch panel (ED-T7) and standard display (E3-DSP)
is 100 m.
