INSTALLATION
PROCEDURE:
1. CHECK
•
Always work safely – disconnect power before
making connections.
•
All wiring must be carried out by suitably qualified
personnel according to the applicable standards.
•
Check for correct operating voltage and power
system. This model (PVD40-500-V-C) is designed
for DC power systems in the range of 450 –
500VDC.
If your power system is a different
voltage, this model is not suitable
. Please
contact your supplier.
•
Always use the correct size HRC fuses.
•
Always use Gg or Gl-rated fuses. Do not use
delay types or ‘semiconductor’ fuses.
2. INSTALL
•
Locate a fuse position as close as possible to the
incoming DC breaker.
•
Install fuse holders or fuse-switch if required.
•
Locate a suitable position for the SPD, ensuring
adequate space for cables. Do not install above
heat-generating objects or in any position that is
exposed to weather.
3. CONNECT
•
Connect wiring - refer to connection diagrams. If
using stranded cable, always use wire ferrules for
lowest resistance and to prevent damage to the
wire.
•
Keep termination length as short as possible.
Do
not wire in extra loops or cable length.
•
Use a suitably-rated cable for alarm connections.
Cable should be rated for operation at the system
voltage and should be 0.5mm
2
to 1.5mm
2
.
4. NOTES:
•
125A fuses are rated such for maximum surge
rating. On services below 125A, fit a fuse lower in
value to the service size.
•
Wiring from fuse to SPD is carrying surge currents
only, not load current. This means that smaller
cables may be used than is normal for the current
rating.
•
If using under-sized cables, some energy
authorities require double insulation (i.e. sleeving)
of the cables.
•
Unplug the alarm connector for termination.
•
Do not Megger test cabling with unit connected –
unit may be damaged.
EARTHING
For proper operation, all surge diverters rely upon a good
earth connection:
•
The main earth wire (from earth link on switchboard to
ground rod or system) MUST be as short and direct as
possible. Extra cable must not be looped.
•
Earth connections from the unit to earth link
MUST
be
as short as possible.
Failure to consider the above points can result in
improper operation of the unit and possible damage to
the installation.
