Auxiliary/control circuit terminals also accept 2x (0.5...1.5 mm²) and 2x (0.75...2.5 mm²) solid, with AWG 2x (20...16) and 2x (18...14). Finely stranded conductors with ferrule: same ranges as solid — 2x (0.5...1.5 mm²) and 2x (0.75...2.5 mm²). Operating temperature range -20 to +70 °C; storage and transport -55 to +80 °C. Rated for 100 % relative humidity during operation. Shock resistance 8g / 10 ms; surge voltage withstand 6 kV. ATEX certification (DMT 98 ATEX G 001) for use in potentially explosive atmospheres.
