Connecting Boards Together

Connect downstream of the

Incoming switch so secondary

board switches with primary board.

Connect upstream of the incoming

switch so secondary board switches

independently of the primary board.

Neutrallink connection

Remove knock out

for N cable to exit

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.

Secondary board 80A max.

Connecting boards with Neutrallink kit

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.
