CONNECTION TO POWER MAINS
DISCONNECT THE UNIT FROM POWER MAINS PRIOR TO ANY ELECTRIC
INSTALLATION OPERATIONS. CONNECT THE UNIT TO A CORRECT INSTALLED
SOCKET WITH A GROUNDED TERMINAL. ANY INTERNAL CONNECTION
MODIFICATIONS ARE NOT ALLOWED AND RESULT IN WARRANTY LOSS.
The unit must be operated only jointly with an automation system that enables the following functions:
1. Disabling power supply to the heater when the fan is off.
2. Air supply to the electric heating elements for heat removal within 2 minutes after the unit is off.
3. Maintaining minimum air speed 2 m/s to avoid heating elements overheating.
4. Power supply cut-off in case of overheating of the electric elements by means of the thermal switches mounted inside of the heater
casing
5. Automatic heating capacity control to keep the maximum air temperature downstream of the electric 40 °C to avoid the
heater overheating and reducing its service life.
The recommended suitable automation system for AOE 9, AOE 12, AOE 15 models is the control unit UET 15D and for the models
AOE 18, AOE 24, AOE 30 is UET 30 D. The control unit UET and the matching mounting kit are available upon separate order. In this case
replace the terminal box with a respective control unit and connect it to the internal terminal blocks of AOE unit in compliance with the
wiring diagram stated in the UET user manual.
The unit with a selected control system is rated for connection to three-phase ac 400 V / 50 Hz power mains. Connection to power
mains of the unit with any control system must be performed with insulated, durable and heat-resistant conductors (cables, wires).
The external power input 400 V / 50 Hz must be equipped with an automatic circuit breaker built into the stationary wiring to
disconnect all the power mains phases. The circuit breaker QF position must ensure free access for quick power-off of the unit. The circuit
breaker trip current must be in compliance with the current consumption of a specific AOE model.
The recommended circuit breaker trip current and the cable cross sections for various AOE models are given un the table below.
However, the conductor selection shall be based on the maximum permissible wire heating depending on the wire type, its insulation,
length and installation method (i.e. overhead, in channels or inside the walls).
