OPERATING CONDITIONS

Control boxes are adapted for installation in closed spaces almost free of dust, gas and inflammable or chemically active vapours. It is allowed to install them in the open air but they have to be protected against precipitations. Mechanical hazard intensity: 3,5g -under continuous acceleration sinusoidal vibration with frequency 5...50 Hz, 10g - under shocks. Height of operation up to 2000m above sea level. Working position - any.
