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
防爆电磁阀是把设备可能点燃性气体混合物的部件全部封闭在个外壳内，
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
，隔爆外壳使设备内部空间与周围的环境隔开。
