BEFORE INSTALLATION:
A. Verify that the system is wired in a Three Phase Star configuration (fig. 5) 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.
B. The SPD must be connected to the Panelboard via a 4 Pole 63A MCCB and adaptor. If the board is compartmentalised then the
appropriate compartment kit is required to segregate the 4 Pole MCCB. (needs to be ordered separately)
SPD MOUNTING POSITION
There are two positions for the SPD.
Position 1 is in the panel board (fig .1 & 2) and Position 2 is in
the cable way (fig.3 & 4).
1. As standard the SPD is mounted in the panel board on the
RH side for the shortest possible wire installation. The 4 Pole
NZM1 must be fitted on the FIRST outgoing way to minimise
the connecting wire lengths.
The SPD status indicators can be viewed through the window
in the inner cover and an auxiliary contact is provided for
external monitoring.

2. Alternative SPD position is adjacent to first outgoing way in the Meter Cableway which allows the SPD Status Indicator to be
viewed externally through a meter aperture.
Mount the SPD in the LH cableway for shortest possible wire installation and optimal viewing of the SPD status indicators,
through the nearest meter aperture.
The 4 Pole NZM1 must be fitted on the FIRST outgoing way to minimise the Earth connecting wire length.

INSTALLATION INSTRUCTIONS:
3. CABLE SPD. (As shown in Fig.1 or 3)
• Excessive wire length and sharp bends degrade SPD performance:
therefore, avoid sharp bends when at all possible and cut excessive
wire lengths to suit the installation.
• Refer to phase ID printed on SPD device for Connecting MCCB Phase
wires N, L1, L2 & L3.
• Bind Cables together with Cable ties for optimum SPD performance.
• Connect the EARTH wire to the nearest bolt on common earth. (see
Fig.1 or 3)
4. Energise the System.
• The Indicator should remain green. If the indicator turns RED, de-
energise and contact the Technical Services department. (See below).
