The modules are notinterchangeable but the method of installing and removal is the same.Do not use, or attempt to repair, a module that has any of the pins on its undersidebent or damaged, because this might affect its safety and will invalidate thecertification.5.3.1.1 Mounting a moduleRefer to Figure 5.4.Orientate the module so that the smaller front clip is facing the user, then:• lower the module so that the safety retaining clip on the TTA housing fits into theloop on the module• locate the terminal pins into their contact sockets on the TTA housing and• push the module home until front and rear retaining clips engage.5.3.1.2 Removing a moduleRefer to Figures 5.3 and 5.4 for further information.Removal is a two-step process that first breaks the electrical connection, followed bythe physical removal of the module from the TTA.• Press the clip at the rear of the module and tilt the module forward until the clipdisengages at the rear.• Press the front clip and withdraw the module from its socket until it is stoppedby the safety retaining clip, then press down on the safety retaining clip enoughto release it and pull the module away from the TTA body without rotating ortwisting it. Figure 5.4 - Mounting a module - e.g. Trunk Surge Protection module5.4 Spur connectionsAll of the spur connections are intrinsically safe and therefore may be live-workedin a hazardous area without ‘gas clearance’, while complying with normal ‘permit towork’ procedures. If spur wiring is removed from a connecting plug, ensure that thesame polarity is observed when it is reconnected.For addtional information refer to Section 4.6 on page 13.
