230 V electrical connection
- The two internal EC fans of the ventilation unit are supplied with 12 V DC and activated using a PWM signal (0 – 5 V).
- The power supply for the ventilation units is provided by the room air control for up to 6 fans (up to 3 PPB 30).
- The room air control is supplied with 230 V AC.
- The unit variant PPB 30 RC has a fully integrated control unit with 230 V connection.
Note the following safety instructions.
Danger of electric shock.
Before installing the electrics, shut down all supply circuits, switch off mains fuse, secure against being accidentally switched back on and position a visible warning sign. During operation, the board cover and front cover of the internal housing must be mounted.
Danger of burns/fire due to overload caused by incorrect connection or connecting too many units to a RLS 45 O / RLS 45 K.
Connect units in accordance with connection diagram. Observe permissible number of ventilation units per room air control/power unit.
Danger of electric shock if the 12 V low voltage and 230 V are not disconnected or are insufficiently disconnected.
Ensure a safety distance between 230 V and 12 V cables. Ensure minimum distance of 8 mm.
Danger of electric shock if the connection on the 230 V input of the PP 45 RC units and the RLS 45 O / RLS 45 K controller is incorrect.
Ensure a phase balance between all components connected to the ventilation system.
Danger of electric shock if the RLS 45 O / RLS 45 K control is installed within the protection zone.
No IP protection present (IP 00). The room air control may only be installed outside protective zones 0, 1 or 2.
Danger of electric shock if the ventilation units are installed within the protection zone.
The units may only be installed in the specified protection zones in accordance with the IP degree of protection. Use PP 45 only outside protection zones 0, 1 and 2. Use PPB 30 O, PPB 30 K only outside of protection zone 0. Use PPB 30 RC only outside of protection zones 0 and 1.
