Equipment Performance
To obtain optimum surge suppression, locate the SPD as close as possible to the circuitry being surge-limited to
minimize the wire length. Minimizing the wire length reduces the impedance between the circuitry and the SPD.
Refer to the Voltage Protection Rating (VPR) values on the SPD nameplate. These VPR values were obtained by
testing the SPD with six-inch long leads (per UL1449). For every additional foot of wire beyond six inches, the
effective VPR increases by approximately 160 volts.

DANGER
HAZARD OF ELECTRIC SHOCK, EXPLOSION, OR ARC FLASH
• Conrm the surge protective device voltage rating on the module or nameplate label is not less than the
operating voltage.
Failure to follow these instructions will result in death or serious injury.
Voltage Rating
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 specier or user of the device should be familiar with the conguration and arrangement of the power
distribution system in which the SPD is to be installed. The system conguration of any power distribution
system is based strictly on how the secondary windings of the transformer supplying the service entrance
main or load are congured. This includes whether or not the transformer windings are referenced to ground
via a grounding conductor. The system conguration is not based on how any specic load or equipment is
connected to a particular power distribution system. See Table 1 for the service voltage of each SPD.

Location of Surge Protective Device (SPD)
UL 1449 Type 1 SPDs have been designed and approved for line side applications prior to the main service dis-
connect without supplemental overcurrent protection. Type 2 SPDs must be installed on the load side of the
main Overcurrent Protective Device (OCPD). All installations should either provide or include a disconnecting
means.
Type 1 SPDs can also be used in Type 2 applications (load side of OCPD). When used on the load side, they
must be installed per local codes.
Locate the SPD as close as possible to the circuit mains being surge-limited 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 (wye
congurations), or phase and ground conductors (delta congurations), must be routed within the same
conduit and tightly bundled or twisted together to optimize device performance. Avoid sharp bends in the
conductors. See Figures 2 and 3.

CAUTION
SPD DAMAGE AND POWER SYSTEM OVER VOLTAGE
• Ungrounded power systems are inherently unstable and can produce excessively high line-to-ground voltages
during certain fault conditions. During these fault conditions any electrical equipment, including an SPD, may
be subjected to voltages which exceed their designed ratings. This information is being provided to the user
so that an informed decision can be made before installing any electrical equipment on an ungrounded power
system.
• Resistance-grounded power systems must be maintained in a over-damped state to limit voltage overshoot and
duration during operation.
• Verication and adjustment of correct power system damping should be done following power system
modications and periodically, as part normal system maintenance.
Failure to follow these instructions can result in injury or equipment damage.
NOTICE
LOSS OF SURGE SUPPRESSION
• Verify that the service entrance equipment is bonded to ground in accordance with all applicable codes.
Failure to follow these instructions can result in equipment damage.
The SPD50K 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 proper voltage suppression by the SPD50K, 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 must be as low as possible and in
compliance with all applicable codes for sensitive electronic and computer systems.
