6. ELECTRICAL INSTALLATION MANUAL
Installation works can be performed only by the specialists that have required qualification. During installation
following requirements must be fulfilled.
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!
6.1. Air Handling Units Sections Connection
After unit parts have been connected together (see unit installation instruction), unit sections connecting
cables and wires are connected.
Connector connection is performed strictly according to numeration given
in wiring diagram, or adequate markings (see unit electric scheme).
When disconnecting unit sections, do not pull by connecting wires and
cables!
6.2. 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 con-
nected to the main switch, which is located on the unit’s outside wall. It is necessary to connect earthing! Types of
cables of connection of electrical power supply are specified in 6.2 Table:

Air handling units designed for 400 V AC supply voltage must be con-
nected to the stationary installation by solid cable. All units must be con-
nected through circuit breaker with max. 30 mA current leakage protection.
Before connecting unit to the electrical power supply, it is necessary to
check whether earthing has been installed properly.
