BEFORE INSTALLATION:
A.
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 label.
If 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 Memshield 3 Panelboard via the Triple Pole 63A MCCB supplied.
NOTE:
If the SPD is to be used in conjunction with equipment other than a Series G Panelboard,
the SPD must be connected via an appropriate protective device for the location of the
installation.
NOTE FOR CLEAN EARTH:
If the system utilises a clean earth, the green/yellow earth wire must be connected to the clean
earth bar.
INSTALLATION INSTRUCTIONS:
1.
ISOLATE INCOMING ELECTRICAL SUPPLY.
2.
SPD MOUNTING POSITION
The SPD should be mounted for the shortest and straightest possible wire installation from
the SPD to the MCCB and Earth/Neutral Busbar. It is strongly recommended that the FIRST
outgoing NZM1 way be used to minimise the connecting wire length.
Excessive wire length and sharp bends degrade SPD performance: therefore, avoid excessive
wire length and sharp bends when at all possible.
3.
ASSEMBLE SPD ENCLOSURE TO STANDARD PANELBOARD (as shown in Fig.1.).
• Position the SPD enclosure on either the left or right side of the Board and align it so that the 27.0 mm
Dia hole is approximately in line with the centre of the lowest outgoing way for a 63A size MCCB.
• Using the SPD enclosure as a template, mark position of holes onto the Panelboard side plate.
• With care, drill 4 holes 6mm dia into the Panelboard side plate and 1 hole 27.0 mm dia in line with
the middle of the MCCB. Fig.1.
• Remove burrs and ensure both enclosures are free of debris.
• Bolt both enclosures in position, ensure that the nuts and shakeproof washers are inside the
Panelboard. Insert grommet in 27mm hole.
4.
CABLE SPD. (As shown in Fig.2).
•
Keep the wire(s) as short as possible for optimum SPD performance.
•
Connect the EARTH wire to the nearest bolt (see Fig.2.).
• Refer to the NOTE for systems utilising the clean earth.
•
Connect the NEUTRAL wire to the Neutral Busbar.
•
Connect Phase wire to the MCCB at L1, L2 & L3.
•
Tie wrap all cables together for optimum SPD performance.
5.
Energise the System.
• For the SPD ‘EPBN1SPD123’ the red Indicator should remain locked in position.
If the red indicator POPS UP, de-energise and contact the Technical Services department.
• For the SPD ‘EPBN1SPD1234’ the Indicator should remain green.
If the indicator turns RED, de-energise and contact the Technical Services department.
