These instructions should be kept with the unit.
Mounting
Mounting location
• The SEH62.1 time switch is designed for indoor use
Measures to be taken to avoid radio interference
• Do not install the time switch near strong electromagnetic fields
• Inductive components near the time switch must be fitted with in-
terference suppressors (RC units or varistors)
• Ensure adequate air circulation to dissipate the heat generated
during operation
• In general, standard cable can be used. If the time switch must be
installed in environments with strong electromagnetic fields,
shielded cable should be used

A On top hat rails.
Type of rail: EN 50 022-35 x 7.5, min. 60 mm long.
