4.1 Dimensions
Appearance and ergonomics:
The appearance has been designed to fi t in harmoniously with the new lines of the refrigeration units.
The main characteristic is its compactness: the dimensions are in fact 34.4 x 76.2 x 65 mm, and 34.4 x 76.2 x 79 mm for the version with traditional transformer.
The drilling templates for both versions are 29 x 71 mm.
Key:
1. version O, L, H;
2. version E, A;
3. drilling template 71x29 mm

(*): relay not suitable for fl uorescent loads (neon lights, ...) that use starters (ballasts) with phase-shift capacitors. Fluorescent lamps with
electronic control devices or without phase-shift capacitors can be used, within the operating limits specifi ed for each type of relay.
