—INTRODUCTIONThis document explains how to install the plug-inABB OVR Surge Protective Devices (SPDs) fortelephone and ISDN lines:OVR TN/RJ11-2/6protects the middle 2 (of 6) conductors ontelephone lines with RJ11 connections.OVR TN/RJ11-4/6protects the middle 4 (of 6) conductors ontelephone lines with RJ11 connections.OVR TN/RJ11-6/6protects all 6 conductors on telephone lines withRJ11 connections.OVR ISDN/RJ45-4/8protects the middle 4 (of 8) conductors on S/Tinterface ISDN lines with RJ45 connections.OVR ISDN/RJ45-8/8protects all 8 conductors on S/T interface ISDNlines with RJ45 connections.2. Before installation2.1 Make sure that the system’s maximum linevoltage (DC or AC peak) will never exceed themaximum working voltage of the SPD.Otherwise the SPD will clamp signal voltagesas though they were transient overvoltages.Maximum WorkingVoltageOVR TN/RJ11 296 VOVR ISDN/RJ45 58 V2.2 Make sure that the SPD’s plug and socketconnections are physically compatible withthose connecting the equipment to thetelephone (or ISDN) line.2.3 Ensure that the current passing through theSPD does not exceed 300 mA.3. Installation3.1 ConnectionThe SPD is connected in series with thetelephone (or ISDN) line (see Figures 1 and 2).If the SPD’s dirty line cable is longer thanrequired, neatly coil and bind the surplus outof the way, keeping this away from cleancables.3.4 EarthingThe SPD must be connected to a goodelectrical earth, either:a) through installation on a TS36 'top hat' DINrail (which in turn is connected to earth), orb) by connecting a crimped 10mm² strandedgreen/yellow cable should be used to bondthe SPD’s earth stud to earth.This SPD earth bond should be less than1 metre long (otherwise the effectiveness ofthe SPD will be reduced).Ideally the SPD would be connected to themain electrical earth or earth star point(located at a distribution board) (see Figure4, overleaf).However, owing to the 1 metre (maximum)earth bond, the SPD will often be hard-wiredto the ring main earth.Never connect the SPD to earth via the earthpin of a plug, as this may be removed.If the earth bond is more than 1 metre fromthe SPD, earth bonds of 2, 3 or 4 metres areallowed if 2, 3 or 4 parallel earth bonds areused. These must be kept at least 5 cm apartfrom each other.The SPD or base plate earth bond should beless than 1 metre long (otherwise theeffectiveness of the SPD will be reduced).10 mm² stranded green/yellow cable shouldbe used for this bond.SPD or base plate earth bonds of 2, 3 or4 metres are allowed if:– 2, 3 or 4 parallel earth bonds are used and– these parallel earth bonds are kept atleast 5 cm apart from each otherWhere even 4 metres of connecting lead isnot sufficient, the incoming cable should bere-routed to bring it within 4 metres of theearth.In circumstances where the cable cannotideally be re-routed, the SPD can alternativelybe connected to the electrical earth local tothe equipment being protected (eg the earthbar of the local power distribution board)(see Figure 4).... continued overleaf1.

Key points of installation1.1 Install protectors very close to the powersupply to be protected, either within thedistribution panel or directly alongside it.1.2 Mount units within a panel or WBXenclosure.1.3 Units are installed in parallel.1.4 Connect to phase(s), neutral and earth.NOTE: Units must have a neutralconnection (see 3.4).1.5 Units installed at power distributionboards can be installed either:- on the load side of the incomingisolator- on the closest available out going way tothe incoming supply1.6 Provide a means of isolation for theESP unit.1.7 The connecting leads to phase/liveterminals should be suitably fused(up to 125 Amps) ensuring fulldiscrimination with the immediateupstream supply fuse.1.8 Connecting leads should be 10 mm 2multi-stranded copper conductor(terminals can accept up to 25 mm 2 ).1.9 Keep the connecting leads as short aspossible and ideally less than 25 cm(10 inches) in length. This may be betterachieved with the equivalent M1Rremote display variant which permitsoptimum positioning of both protectorand display.1.10 Bind the connecting leads tightlyover their entire length.1.11 Maximum torque for power terminals is2.9Nm, wire stripping length 17mm.1.12 Maximum torque for remote contact is0.25Nm, wire stripping length 7mm.1Installation instructionsESP M1/M1R mains protectorsFigure 2:Plug-in series connection for OVR ISDN/RJ45-4/8 and 8/8.Figure 3:Cable routeing.
