Electrical connection

Danger due to electric shock

• Observe the safety rules of electrical engineering. Before taking off covers and before installing the electrics, shut down all supply circuits, switch off mains fuse, check that no voltage is present, secure against being accidentally switched back on and position a visible warning sign.

• Observe the applicable regulations for electrical installations, e.g., DIN EN 50110-1 and DIN EN 60204-1, in Germany in particular VDE 0100 with the corresponding parts → in case of non-observance, danger of electric shock, fire or short circuit.

• Only connect the ventilation unit to a permanently wired electrical installation in accordance with circuit diagram/wiring diagram.

• Observe the voltage and frequency specified on the rating plate:
  230 V AC for RLS 45 O, RLS 45 K, PP 45 RC, PPB 30 RC
  12 V DC for PP 45 O, PPB 30 K, RV 2

• Use a mains isolation device with contact openings of at least 3 mm at each pole. Avoid contact with components (damage due to static charge).

• Permitted connection cables: Mains connection/230 V: Type NYM-J 5G 1.5 mm²
  Control cables: Type J-YSTY, 0.8 mm, 4-core, max. 25 m from star point, max. 4 m to star point.

• The ventilation units and controls are not suitable for use in protection zones PP 45 and RV 2 ventilation units with degree of protection IP 00, PPB 30 ventilation units with IP X4 → Danger of electric shock/short circuit due to moisture ingress or condensation → Damage to unit due to moisture ingress. Protect the ventilation unit from humidity and moisture.
  • Use room air control and radio switch only outside protections zones 0, 1 and 2.
  • Use PP 45 and RV 2 ventilation units only outside protections zones 0, 1 and 2.
  • Use PPB 30 O, PPB 30 K ventilation units only outside protection zone 0.
  • Use PPB 30 RC ventilation units only outside protections zones 0 and 1.

• Ensure that the signal input on the RLS 45 O/RLS 45 K control unit is connected correctly. If the 230 V mains voltage is connected incorrectly in the connection area/at the signal input → Danger of electric shock, fire or short circuit if this is not observed. Ensure a phase balance between all components connected to the ventilation system.

• No or insufficient separation of the 12 V/24 V extra-low voltage with 230 V → If not observed, danger of electric shock, fire or short circuit. Ensure a safety distance between 230 V and SELV cables. Observe a minimum distance of 8 mm

DANGER due to short circuit/fire with 230 V units (PP 45 RC, PPB 30 RC)

• If moisture or condensation enters the terminal compartment, there is a danger of short circuit and fire, e.g. if the cable grommet is inserted incorrectly or if the wall sleeve is installed at an angle to the interior wall. Ensure that the cable grommet is firmly and tightly seated in the housing. The inner front cover must engage correctly in the housing and be tight all round. The wall sleeve must not be inclined to the interior wall (permissible installation position 1° to 2° inclination to the exterior wall). Seal additionally, if necessary.

• Damage to unit if moisture or condensation enters the terminal compartment of the ventilation unit (12 VDC). E.g. if the cable grommet is installed incorrectly, the terminal box cover is installed incorrectly or the installation position is inclined towards the interior wall.
  PP 45 and RV 2 devices with IP 00, PPB 30 devices with IP X4.
  PPB 30 O/K: The grommet must be firmly and tightly seated in the housing, the inner front cover must be correctly engaged in the housing and tight all round. Seal additionally, if necessary.
  PP 45 O/K/RC and PPB 30 O/K/RC: Insert wall sleeve with 1 to 2° inclination to the exterior wall.
  RV 2: Insert the terminal box cover tightly all round. The mounting sleeve, external cover and inner cover must be fitted correctly and tightly.
