Voltage Rating
HAZARD OF ELECTRIC SHOCK, EXPLOSION, OR ARC FLASH
Confirm the SPD voltage rating on the module or nameplate label is the
same as the operating voltage.
Failure to follow these instruct ions will result in death or serio us injury.
Prior to mounting the SPD, verify that the device has the same voltage rating as
the power distribution system in which it is installed. Compare the nameplate
voltage or model number on the SPD with the nameplate of the electrical
distribution equipment.
The specifier or user of the device should 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 2 for the service
voltage of each SPD.

Location
Location of SPD Install Type 2 SPDs on the load side of the main Overcurrent Protection Device
(OCPD) to comply with NEC Article 285 for Type 2 SPDs.
Locate the SPD as close as possible to the circuit being addressed to minimize
the wire length and optimize SPD performance. Avoid long wire runs so that the
device will perform as intended. To reduce the impedance that the wire displays
to surge currents, the phase, neutral, and ground conductors must be routed
within the same conduit and tightly bundled or twisted together to optimize
device performance. Avoid sharp bends in the conductors. See Figure 2.

WARNING
Grounding
Grounding
HAZARDOUS TOUCH VOLTAGE
• Connect the SPD ground terminal to the building grounding grid
structure.
• Use an appropriately sized equipment grounding conductor.
• When using metallic raceway or conduit:
— Do not use the SPD ground unless augmented with an insulated
equipment grounding conductor installed inside the metallic raceway or
conduit.
— Do not use isolated bushings to interrupt the metallic raceway or
conduit.
— Maintain electrical continuity at all raceway and conduit connections
using appropriate bonding devices.
• Do not use a separate isolated ground for the SPD.
• Verify proper equipment connection to the grounding system.
• Verify ground grid continuity by performing regularly scheduled
inspections and testing as part of a comprehensive electrical
maintenance program.
Failure to follow these instructions can result in death or serious injury.
The SPD has leakage current to ground when energized and can present a
hazardous touch voltage.
The device has SPD elements connected from phase to ground. To prevent
hazardous touch voltage on the SPD enclosure during normal operation or
during SPD end-of-life, 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 (if
present) connection of the power system. The SPD should not be connected to
a separate isolated ground.
When metallic raceway is used as the wiring method, an insulated grounding
conductor should be run inside the raceway and sized in accordance with all
applicable codes. Maintain electrical continuity at all raceway connections using
appropriate bonding devices and do not install isolating bushings to interrupt a
metallic raceway run.
For best overvoltage suppression by the 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 IEEE 142-2007). The ground impedance
measurement of the electrical system should be as low as possible, and in
compliance with all applicable codes.
SPDs rated for use on solidly-grounded power systems must not be connected
to resistance-grounded (for example HRG) or ungrounded power systems.
Such a connection can result in damage to the components within the SPD.
