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 63A 4P MCB onto the stabs with the back end hooked on the din rail whilst

Energise the System.
The Indicator should remain green. If the indicator turns RED,
de-energise and contact the Technical Services department.
