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

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.
