5. ELECTRICAL INSTALLATION MANUAL
Installation works may be performed only by duly qualified personnel. The following requirements
must be fulfilled during installation.
It is recommended to lay control circuit cables separately from power cables or to
use shielded cables. In this case, the cable shielding must be grounded!
5.1. Air Handling Units Sections Connection
After unit parts have been connected together (see Units Installation Instructions), the connecting
cables and wires of the sections of the unit are connected.
Connector connection is performed strictly according to numeration given in wir-
ing diagram, or adequate markings (see unit electric scheme).
When disconnecting sections of the unit, do not pull connecting wires and cables!
5.2. Electric Power Supply Connection
Electric power supply (400 V AC; 50 Hz voltage) is connected to the main switch, which is envisaged
in the heat exchanger (middle) section of the air handling unit. Prior to connecting to the power supply,
the main switch must be installed near the unit in the intended place or directly on its wall. It is necessary
to connect earthing!
It is recommended to connect AHU to the mains via automatic circuit breaker with
300 mA current leakage protection (type B or B+).
Earth must be installed according EN61557, BS 7671.
The power supply cable of the unit and electrical heater is selected according to the maximum cur-
rent strength indicated in the presented technical data sheet. The cable types are indicated in Table 5.2.
