Surge Protective Device (SPD) Location Considerations
Environment
The device is designed to operate in an ambient temperature range of -25° C (-13° F) to +60° C (140° F) with a
relative humidity of 0 to 95% non- condensing.
Audible Noise
The device background noise is negligible and does not restrict the location of the installation.
Mounting
The device is designed to be surface mounted. Refer to the device submittal drawings or the product catalog
for typical mounting dimensions and weight.
Service Clearance
The service clearance must meet all applicable code requirements.

Equipment Performance

To obtain the maximum system performance, locate the device as close to the circuit being addressed as
possible to minimize the interconnecting wiring length. For every foot of wire length, approximately 160 Volts
(6 kV / 3 kA, 8/20 microsecond) is added to the suppressed voltage. The Voltage Protection Rating (VPR) is
located on the device nameplate and is measured six inches from the enclosure sidewall, according to
UL 1449 test standards.

Voltage Rating

HAZARD OF ELECTRIC SHOCK, EXPLOSION, OR ARC FLASH
• Confirm the SPD voltage rating on the module or nameplate label is not less than operating voltage the operating
voltage.
Failure to follow these instructions will result in death or serious 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 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 ground
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.
