CHECK• Always work safely – disconnect powerbefore making connections.• All wiring must be carried out by suitablyqualified personnel according to theapplicable standards.• Check for correct operating voltage andpower system. This model (SPDT60-255) isdesigned for power systems in the range of220-250V(380-440V). If your power systemis “delta” (i.e. ungrounded), or a differentvoltage, this model is not suitable. Pleasecontact your supplier.• Connect only between Neutral and Earth.• No fuse is necessary.2. INSTALL• Locate a suitable position for the SPD,ensuring adequate space for cables. Do notinstall above heat-generating objects or inany position that is exposed to weather.• Plan for cables as short as possible.• Install unit to DIN-rail in switchboard orcabinet.3. CONNECT• Connect wiring - refer to connectiondiagrams. If using stranded cable, alwaysuse wire ferrules for lowest resistance and toprevent damage to the wire.• If connecting with Eaton SPDV60 SPDs, usesupplied neutral linking bar.• Use a suitably-rated cable for powerconnections. Cable should be rated foroperation at the system voltage and shouldbe 6mm2 to 25mm 2.• Use short cables for all connections orprotection will be reduced.• Use a suitably-rated cable for alarmconnections. Cable should be rated foroperation at the system voltage and shouldbe 0.5mm2 to 1.5mm 2.4. NOTES:• Maximum alarm relay resistive load is 2A.• Unplug the alarm connector for termination.• It is recommended not to connect the alarmcontacts to AC mains circuits if possible, toprevent flashover from surges on the AC line.Connect to a PLC or BMS if available.• Do not Megger test cabling with unitconnected.EARTHINGFor proper operation, all surge diverters rely upon agood earth connection:• The main earth wire (from earth link onswitchboard to ground rod or system) MUST beas short and direct as possible. Extra cable mustnot be looped.• Earth connections from the unit to neutral or earthlink MUST be as short as possible.Failure to consider the above points can result inimproper operation of the unit and possibledamage to the installation.
