LPU-Ex has to be bulkhead mounted because of too little
space or zone 0 at actuator
Like other LPU’s LPU-Ex can be bulkhead mounted by means of BB-block or BB-VPI, but then needs an
intrinsically safe position indicator. All LPU-Ex can be delivered with integrated intrinsically safe outlet
for position indicator (ia) to solve the problem.
Note! For LPU-Ex with ia-outlet the hole for DPI in LPU must contain a special plug to ensure that
flameproof enclosure of LPU-Ex is maintained. This plug is delivered with ia-parts and
must always be used for ia-versions.
