●If infrared heaters are connected, they must have a safety temperature limiter.

For suitable infrared heaters see 2.1. Intended use on page 5.

●If infrared plates are connected, the WC4-IRF-F foil sensors must be used

and activated (see 4.3. Installing the foil temperature sensor on page 13

and 5.5. Connecting the foil sensor (optional) on page 16). For suitable

infrared plates see 2.1. Intended use on page 5.

●Automatic heating period limiter

The infrared controller shuts down automatically after the maximum heat-

ing period for safety reasons (see also 6.3. Operating time on page 21).

The EN 60335-2-53 species a maximum heating period limit of 6 hours

for private infrared cabins. For infrared cabins in hotels, apartment blocks

and similar locations, a maximum heating period limit of 12 hours is

permissible. Extending the heating period limit to 18 hours or 24 hours

is only permitted in public infrared cabins.

!

The Infrabox infrared controller is suitable for use with intrinsically safe

infrared heaters and infrared plates. If no intrinsically safe products are

being used, a safety temperature limiter must be connected.

Installation instructions, for professionals only p. 10/38

4. Installation

4.1. Installing the power supply unit

ATTENTION!

Damage to the unit

●Install the power supply unit in a dry place. Maintain a maximum ambient

temperature of 40 °C and a maximum humidity of 95%.

●A free circulation of air must be ensured to cool the power supply unit. The pow-

er supply unit must not be covered by any objects or materials.

The power supply unit is installed on the cabin roof (Fig.1), on the cabin wall or in

another suitable location in accordance with the ambient conditions. The power

is supplied with a mains connection cable and safety plug.

1. Screw the Infrabox power supply unit housing to the cabin ceiling or the cabin

wall with the four wooden screws provided (16 mm long).

Fig. 1 Installing the power supply unit

EN

Installation instructions, for professionals only p. 11/38

4.2. Installing the control unit

The control unit 2 of the infrared controller is installed on the outside wall of the

cabin with a maximum clearance of 10 metres from the power supply unit 1 (see

Fig. 2). For the installation, a standard jigsaw is required to cut out the recess for

the control unit. The control unit can be installed both inside and outside the cabin.

* For installing inside an infrared cabin, a minimum clearance of 30 cm

must be maintained (see Fig. 2 Control unit position on page 11).

ATTENTION!

Damage to the unit

●The control unit 2 of the infrared controller is splashproof (protection

class IP X4).

●Work on the control unit must only be carried out using a standard screwdriver.

Using a cordless screwdriver may cause irreparable damage to the housing.

Installation instructions, for professionals only p. 13/38

If the foil temperature sensor is not tted directly on the infrared plate,

it will produce incorrect measured values. Install the foil temperature

sensor directly on the foil.

The foil temperature sensor is only required for infrared plate heating sys-

tems. Observe the details of the plate heating system manufacturer here.

4.3. Installing the foil temperature sensor

The foil temperature sensor is installed directly on the infrared heating plate and

xed with a cable strain relief (seeFig. 5: Installing the foil temperature sensor

on page 13)

Install the sensor head 1 of the foil temperature sensor directly between

the insulation and heating foil 4.

1. Secure the foil temperature sensor with the strain relief 2 outside

the foil area.

2. Lay the 2-pin cable 3 in the cabin wall and secure with cable ties.

3. A foil temperature sensor must be activated to use it (6.4. Foil sensor on

page 22).

Installation instructions, for professionals only p. 14/38

5. Electrical connection

Observe the following points when connecting the power to the infrared controller:

●Work on the infrared controller may only be performed when the power has

been disconnected.

All components on the Infrabox power supply unit are connected as shown in

Clamp the foil sensor line on the 2-pin foil sensor plug to FF accord-

ing to Fig. 6: Connection area for sensor/control unit on page 14.

5.6. Connecting the HV input (remote start/enable input)

The input becomes active by applying alternating current

(230 V / 50 Hz) – depending on the remote start or enable input

setting. The input is connected using 2-pole HV plug according to

Fig. 7: Connection area for 230 V on page 15.

The EN 60335-2-53 states that the controller (in the remote start

setting) must be set to “Standby for remote operation” mode before

each remote start procedure.

Refer to chapter 6.9. HV input (remote start/enable input) on page

29 to follow the exact step-by-step procedure.

WARNING!
