1. 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 shield-
ing!
Ak sa AHU používa vonku, všetky káble a vodiče, ktoré sú vedené mimo
jednotky, musia byť dodatočne chránené pred poškodením UV žiarením;
môže byť napríklad namontovaný vo vnútri káblového žľabu, vlnitej rúrky
alebo podobne.
1.1. 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 giv-
en in wiring 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 correspond
-
ing 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 specified in the wiring diagram.
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
connected through circuit breaker with 300 mA current leakage protec-
tion (type B or B+).
Before connecting unit to the electrical power supply, it is necessary to
check whether earthing has been installed properly.
