ELECTRICAL CHARACTERISTICS Standard voltages DC (=) : 24V - 48V - 240V (Other voltages and  60 Hz on request) AC (~) :
 24V - 48V - 115V - 230V / 50 Hz TEMPERATURE CLASSIFICATION TABLES AC (~) Solenoids DC (=) Solenoids
A 35,1 W DC, HC coil is available for battery voltages. Range +12% to -28% of nominal voltage (only available on NB construction)
隔爆外殼存在間隙，因電氣設備呼吸作用和氣體滲透作用，
使內部可能存在性氣體混合物。

CONNECTIONS ? Any ATEX approved dia. 9-12 mm cable entry device can be ? tted in the M20 x 1,5: use pre? x NAET or NBET;
 refer to the nameplate for maximum cable temperature (optionally 1/2 NPT / ? 8,5-16 mm, use pre? x NAT or NBT).
Internal and external earthing connection ? The operator can be rotated 360° at 90°
increments to select the most favourable position for cable entry
防爆電磁閥是把設備可能點燃性氣體混合物的部件全部封閉在個外殼內，
solenoid size maximum ambient °C (3)
 Actual temperature range can be limited depending on valve operation limits.
OPTIONS ? Non-polarised voltage surge suppressor for DC constructions
，隔爆外殼使設備內部空間與周圍的環境隔開。
