INM 9370-RD Rev 5195.4.1 Removing a Spur Surge module & spur cable adjustmentIf an FS32 Spur Surge module needs to be removed from circuit, it will probably benecessary to increase the cable length inside the enclosure slightly to allow the spurwiring connector to be plugged into the circuit board. Use the following procedure.a) Loosen the two screws securing the pluggable, spur-wiring connector to theSpur Surge module and unplug it.b) Loosen all three of the Spur Surge module’s fixing screws and unplug it from thecarrier.c) Loosen the spur cable gland.d) Pull an additional 20 mm (approx.) of additional cable length into the enclosure.e) Plug the spur connecting plug into its mating socket on the barrier carrier andtighten the fixing screws to a recommended torque value of 0.4 Nm.f) Finally, make any necessary adjustments to the cable to avoid any tension, thentighten the spur cable gland to clamp the cable to retain the IP rating of theenclosure.5.4.2 Adding a Spur Surge module & spur cable adjustmentIf an FS32 Spur Surge module is added, it will probably be necessary to reduce thecable length inside the enclosure slightly when connecting the spur wiring connectorto the Spur Surge module. Refer also to Section 4.6.1 on page 13 for further fittingdetails.a) Loosen the two screws securing the pluggable, spur-wiring connector to thecarrier and unplug it.b) Plug the Spur Surge module into the vacant socket on the carrier and tighten thetwo fixing screws and its grounding screw, all to a recommended torque of 0.4Nm.c) Loosen the spur cable gland.d) Withdraw approximately 20 mm of the cable length from the enclosure.e) Plug the spur connecting plug into its mating socket on the Spur Surge moduleand tighten the fixing screws to a recommended torque of 0.4 Nm.f) Finally, make any necessary adjustments to the cable to avoid any tension,then tighten the spur cable gland to clamp the cable to retain the IP rating ofthe enclosure.5.5 Trunk connectionsWARNING!No work is permitted on any part of the Trunk Terminal Assemblywhile the enclosure is powered, unless the environment is known tobe non-hazardous.Before any work starts on the Trunk Terminal Assembly the trunk power to theenclosure must be isolated, or a gas clearance certificate obtained.Once the conditions are known to be safe, the protective plastic cover of the TrunkTerminal Assembly (TTA) may be removed. Unscrew its securing screw, slide it outuntil it becomes free and then move it to the side to obtain access.Refer to Section 4.2 on page 8 and Section 4.3 on page 11 for additionalinformation about trunk wiring connections.When any changes or checks have been carried out, ensure there are no looseimplements left inside the TTA before replacing its protective cover. Slide the coverinto its locations and tighten the securing screw to a recommended torque of 0.6Nm.
