INSTALLATION
Refer to the procedure and diagram shown to
connect the SPDT60-255.
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 (SPDT60-255) is
designed for power systems in the range of
220-250V(380-440V).
If your power system
is “delta” (i.e. ungrounded), or a different
voltage, this model is not suitable
.
Please
contact your supplier.
•
Connect only between Neutral and Earth.
•
No fuse is necessary.
2. INSTALL
•
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.
•
Plan for cables as short as possible.
•
Install unit to DIN-rail in switchboard or
cabinet.
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.
•
If connecting with Eaton SPDV60 SPDs, use
supplied neutral linking bar.
•
Use a suitably-rated cable for power
connections. Cable should be rated for
operation at the system voltage and should
be 6mm
2
to 25mm
2
.
•
Use short cables for all connections or
protection will be reduced.
•
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:
•
Maximum alarm relay resistive load is 2A.
•
Unplug the alarm connector for termination.
•
It is recommended not to connect the alarm
contacts to AC mains circuits if possible, to
prevent flashover from surges on the AC line.
Connect to a PLC or BMS if available.
•
Do not Megger test cabling with unit
connected.
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 neutral or 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.
