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(shè)備可能點(diǎn)燃性氣體混合物的部件全部封閉在個(gè)外殼內(nèi)，
