ENGLISH
The specifier or user of the device must be familiar with the configuration
and arrangement of the power distribution system in which any SPD is to be
installed. The system configuration of any power distribution system is
based strictly on how the secondary windings of the transformer supplying
the service entrance main or load are configured. This includes whether or
not the transformer windings are referenced to earth via a grounding
conductor. The system configuration is not based on how any specific load
or equipment is connected to a particular power distribution system. See
Table 1 for the service voltage of each SPD.

In addition to the power system configuration
and voltage, the power system grounding
method must be considered when selecting the
appropriate IMA device. Refer to the following
chart for information concerning the suitability of
IMA device to specific power system grounding
method.
CAUTION
Rev. 01, 06/2016 Grounding
General The IMA has SPD elements connected from phase to ground. It is critical
that there be a robust and effective connection to the building grounding
structure. The grounding connection must utilize an equipment grounding
conductor run with the phase and neutral connection of the power system.
Do not connect the SPD to a separate isolated ground.
For best overvoltage suppression by the IMA SPD, use a single-point
ground system where the service entrance grounding electrode system is
connected to, and bonded to, all other available electrodes, building steel,
metal water pipes, driven rods, etc. (for reference, see NEC Art 250). The
ground impedance measurement of the electrical system should be as low
as possible and in compliance with all applicable codes.

• Do not connect devices rated for use on solidly-grounded power systems
to resistance-grounded (for example, High Resistance Ground) or
ungrounded power systems.
• Verify that the service entrance equipment is bonded to ground in
accordance with all applicable codes.
• Verify that the neutral terminal of the power system transformer feeding
the device is bonded to system ground in accordance with all applicable
.
codes

Failure to follow these instructions can result in equipment damage.
SPDs rated for use on solidly-grounded power systems must not be connected
to resistance-grounded or ungrounded power systems. Such a connection can
result in damage to the SPD.
Always verify the power system grounding configuration prior to application
of power to the device. Confirm that all ground bonds are installed at both
the service entrance equipment and power system transformer prior to
application of power.

ENGLISH
Follow the steps listed below when making wiring connections:
1. Turn off all power supplying this equipment before working on or inside
any enclosure containing this equipment.
2. Confirm the SPD voltage rating and configuration is the same as the
system voltage and power system configuration to which it will be
connected.
3. Identify proper location for surge protective device. Locate as close as
possible to the panel being addressed so the wires are as short as
possible. Mount unit securely.
Note: The surge protective device must be installed in an accessible
location as described in the NEC.
4. Install in accordance with national and local electrical codes for
overcurrent protection recommendations and wire ampacity
considerations.
Note: The neutral connection is not present on three-wire, three-phase
wye ground or two-wire single-phase mid-point ground power systems.
For these systems, bond the neutral and ground lugs together in the
SPD. For a High Resistance Ground (HRG) or Delta SPD, no neutral
connection exists. For installation wiring see Figures 6 and 7.
Note: See Terminals, Wire Size, and Installation Torque and Table 2 on
page 7 for acceptable wire size and installation torque.
5. Twist conductors ½ turn or more for every twelve inches of length. Do
not loop or coil wires. Be sure to maintain adequate wire bending space
per NEC.
6. If the remote signaling contacts of the diagnostic display panel are to be
used, refer to the section, “Dry Contacts”, on page 18 for wiring
instructions.
7. On a High-Leg Delta installation, note the high leg connection per wiring
diagram. See Figure 5.
8. Replace all devices, doors and covers before turning on power to the
equipment. If the SPD is properly installed and functioning, the green
LED indicators on the display will be lit.
For questions pertaining to the installation of this device, contact the
Surgelogic Technical Assistance Group at 1-800-577-7353.
