Before Installation: Verify that the system is wired in a Three Phase Star configuration and that the voltage rating of the system matches the
voltage rating of the SPD as shown on the label.
If the Neutral to Earth voltage is greater than 5 VAC, then a problem may exist in the electrical system. The SPD may be installed; however, a
qualified person should be consulted to correct the problem.
Installation Instructions:
• Fit SPD mounting bracket assembly to the back plate in the position 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
• Connect the EARTH wire to the nearest bolt on common earth.
Energise the System. The Indicator should remain green. If the indicator turns RED,
de-energise and contact the Technical Services department.
