When the neutral link kit is fitted
then the cable is made up with a M6
lug and connected to the link
terminal as shown. The other end is
connected to the incoming neutral
terminal on the secondary board.
Make up 16mm² tri rated cable with Cembre ANE 3-U 5
fork connectors and connectto the incoming switch
fork terminals of the primary board. The other end of
the cables are connected to the main incoming
terminals on the Secondary board.

Before Installation: Verify that the system is wired in aThree Phase Star configuration and that the voltage rating of the system matches the
voltage rating ofthe SPD as shown on the label. If the Neutral to Earth voltage is greater than 5 VAC, then a problem may ex ist in the electrical
system. The SPD may be installed; however, a qualified person should be consulted to correctthe problem.
Installation Instructions:
• Disconnect the neutral cable from the SPD and remove the SPD and MCB from the
mount. Fit the mounting bracket assembly to the back plate in theposition shown.
• Fit 63A 4P MCB onto the stabs with the back end hooked on the din rail whilst
fitting the SPD device on the din rail next to it. Tighten the MCB terminals to 2.4Nm.
• Reconnect the Neutral cable to the SPD. Tighten to 2.4Nm.
• Connect the EARTH wire to the nearest common earth bolt. Tighten to 15Nm.
Energise the System. The Indicator should remain green.If the indicator turns RED,
de-energise and contactthe Technical Servicesdepartment.
