1.0 Installation
The SolaHD STV100K Series Surge Protective Device is a high-quality, high-
energy surge current diversion system designed to protect sensitive equipment
from damaging transient voltage surges resulting from load switching, lightning
strikes, and other sources.
The installer should perform the following steps to ensure a quality installation.
Please read all instructions before starting the installation of this product. These
instructions do not replace national or local electrical codes. Check applicable
codes to ensure compliance.
!DANGER!Onlyqualiedpersonnelshouldinstallorservicethissystem.Elec-
tricalsafetyprecautionsmustbefollowedwheninstallingorservicingthisequipment.
Topreventriskofelectricalshock,turnoffandlockoutallpowersourcestotheunit
beforemakingelectricalconnectionsorservicing.
1.1Environment
The unit is designed for operation indoors in an ambient temperature range of
-40°C to +60°C (-40°F to +140°F), with a relative humidity of 0% to 95% non-
condensing.
The unit is provided in a metallic industrial enclosure. Do not install in areas with
excessive dust, corrosive vapors, ammable materials, or explosive atmospheres.
1.2Mounting
Mount the unit as close as possible to the service panel. For best performance,
the unit should be positioned so that the length of the wiring to the surge protec-
tive device (SPD) is minimized.
1.3ProperConnectionofSPDs
Type 2 SPDs shall be installed as dened in the National Electric Code (NEC)
2011 Edition as follows:
285.24Type2SPDs(TVSSs)
Type 2 SPDs (TVSSs) shall be installed in accordance with 285.24 (A) through (C).
(A)Service-SuppliedBuildingorStructure.Type 2 SPDs (TVSSs) shall be
connected anywhere on the load side of a service disconnect overcurrent device
required in 230.91, unless installed in accordance with 230.82(8).
(B)Feeder-SuppliedBuildingorStructure. Type 2 SPDs (TVSSs) shall be
connected at the building or structure anywhere on the load side of the rst over-
current device at the building or structure.
(C)SeparatelyDerivedSystem. The SPD (TVSS) shall be connected on the
load side of the rst overcurrent device in a separately derived system.

1.5VoltageProtectionRatings(VPRs)
To maintain the voltage protection ratings marked on these products, as obtained
by Underwriters Laboratories, Inc. in accordance with ANSI/UL 1449, 3rd edition,
the Standard for Safety, Surge Protective Devices (SPDs), #12 AWG wire must
be utilized to connect the STV100K Series to your facility’s power grid. Connec-
tions made with conductors other that #12 AWG may result in different VPRs.
1.6CircuitAmpacityLimitations
This device has been investigated by Underwriters Laboratories, Inc. to with-
stand, without exposing live circuits or components on power sources, a voltage
of two times (2x) the device’s ratings, and fault currents of up to 65,000 AIC, as
described in ANSI/UL 1449, 3rd edition, the Standard for Safety, Surge Protective
Devices (SPDs).
1.7WireSizing/Routing
Phase, N, and GND wires are #12 AWG. NO, NC, and COM wires are #18 AWG.
To reduce the wiring impedance to surge currents, we recommend the phase,
neutral (if required), and ground conductors to be twisted together and routed in
the same raceway (conduit). Avoid any sharp bends in the conductors. All wiring
must comply with the National Electrical Code (NEC) and applicable local codes.
STV100K Series Instruction Manual • 6
1.8WiringConnections
Before making connections to the unit, verify that
the unit model number and nameplate voltage rating
are appropriate for connection to the intended power
source. See Table1 for voltage rating applications with
typical power source congurations.
1. Connect the black phase wires to the corre-
sponding phase on the service panel. For delta
high leg units, ensure the high leg is connected to
Phase B of the SPD.
2. Connect the white neutral wire of the SPD (if
provided) to the neutral of the supply. Connect the
green ground wire of the SPD to source ground.
3. If you are not using the relay contacts for remote
sensing, cut and dress the orange COM wire, the
blue NC wire, and the yellow NO wire in the conduit.
For remote sensing, wires are connected to COM,
NC, and NO respectively. (125 V ac, 5 A max.)
! DANGER!Forproperandsafeoperation,neutraland
ground MUST be reliably connected. Failure to operate
this unit from a solidly grounded power source of the
propercongurationwillreduceorimpedeoperationand
mayresultinunitfailure.
NOTES:
• Figure 2 is a three-phase wye. A three-phase delta will have no neutral
wire. For a three-phase delta high leg, Phase B will be the high leg. A split
phase unit will have no Phase C and can be labeled Line 1 and Line 2.
• A single-phase L-N unit will have one black phase wire, a white neutral
wire, and a green ground wire. A single-phase L-L unit will have two black
phase wires and the green ground wire.
• Summary alarm Form C (1 NO and 1 NC) relay contacts may be provided
for remote indication of an SPD failure. This indication may also consist of
a phase loss or undervoltage condition.
• Summary alarm Form C relay contacts are rated 5 A at 250 V ac maximum
with a power factor of 1.0. For units with Summary Alarm Contacts, access
to the contacts are provided via #18 AWG wires (yellow NO, orange COM,
and blue NC).
1.9ApplyingPower
Apply power to the SPD and ensure status indications are normal. Under normal
conditions, the green LEDs are illuminated and the red “Service” LED is extin-
guished. If normal status indication does not exist, see “2.0 Troubleshooting”.
