Caution! When using an RGB and RGT on an LMU7, the RGT-connection must be
carried out as a 3-wire connection (terminal 1, 2 and 3). Otherwise, the right to
claim under garantee becomes invalid.
Cable lengths
Bus cables do not carry mains voltage but carry low voltage. They must not be rou-
ted in parallel to the mains cables (interference signals). Otherwise shielded cables
should be used.
Permitted cable lengths:
Cu-cable up to 20m: 0.8 mm
Cu-cable up to 80m: 1 mm
Cu-cable up to 120m: 1.5 mm
Cable types : e.g. LIYY or LiYCY 2 x 0.8
