1. ELECTRICAL INSTALLATION MANUAL
Installation works can be performed only by the specialists that have required qualication. During
installation following requirements must be fullled.
It is recommended to lay control cables separately from power cables, or use
shielded cables. In such case it is necessary to earth cable shielding!
If AHU is used outdoors, all cables and wires, that are routed outside of the unit
must be additionally protected from UV damage; for example it can be mounted
inside of cable tray, corrugated tube or similar.
1.1. Air Handling Units Sections Connection
Af ter unit p ar ts h ave been co nnec te d toge ther (se e unit ins talla tion ins truc tio n), unit sec tions co nnec ti ng
cables and wires are connected.
Connector connection is performed strictly according to numeration given in wir-
ing diagram, or adequate markings (see unit electric scheme).
When disconnecting unit sections, do not pull by connecting wires and cables!
1.2. Electric Power Supply Connection
If the air handling unit voltage is ~230 V; 50 Hz it is necessary to install the socket with grounding of
corresponding capacity (see electric diagram unit). If the voltage is ~400 V; 50 Hz, the cable of electrical
power supply is connected to the main switch, which is located on the unit’s outside wall. It is necessary
to connect earthing! Electrical power supply connection and other cable thicknesses are specied in the
wiring diagram.
Air handling units designed for 400 V AC supply voltage must be connected to
the stationary installation by solid cable. It is recommended to connect AHU to
the mains via automatic circuit breaker with 300 mA current leakage protection
(type B or B+).
Before connecting unit to the electrical power supply, it is necessary to check
whether earthing has been installed properly.
