3.0 Preinstallation
3.1 Unpacking & Preliminary Inspection
1. Inspect the shipping crate(s) for damage or signs of mishandling before
unpacking the unit.
2. Remove any securing bands and cardboard packing and inspect the unit for
any obvious shipping damage.
3. Ifanyshippingdamageisobserved,immediatelyleaclaimwiththeshipping
agency and forward a copy to your SolaHD Representative.
3.2 Storage
The unit should be stored in a clean, dry environment. The storage tempera-
ture range is -55°C to +85°C (-67°F to +185°F). Care should be taken to avoid
condensation.
All packing and shipping materials should be left intact until the unit is ready for
nalinstallation.Iftheunithasbeenstoredforanextendedperiodoftime,it
should be cleaned and carefully inspected before placing into service.
3.3 Location Considerations
Environment: The unit is designed for indoor operation in an ambient tempera-
ture 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 an industrial-use enclosure, which is dust-tight and drip-
tight.Itshouldnotbeinstalledinareaswithexcessivedust,corrosivevapors,
ammablematerials,orexplosiveatmospheres.
Audible Noise: The audible noise of the unit is less than 40 dB at 5 feet, which
allows placement within most rooms (if desired).
Service Clearance: 36 inches (914 mm) minimum is recommended for units with
hinged doors that open to the front.
Mounting: The unit is intended to be wall mounted. See Figure 4 for dimensions.
Tip: To maximize system performance, locate the unit as close as possible to the
protected circuit and keep interconnecting wiring less than 5 feet.
For optimum transient surge protection, coordinated surge suppression should
be applied at the service entrance and all other electrical connections to the
building (e.g. telephone, CATV); also at known surge generating loads within the
building (e.g. large motors, arc welders, switched capacitors); as well as sensitive
electronic loads (e.g. computers, electronic appliances, solid state motor drives).
For interconnected electronic loads (by the way of data cabling), transient surge
suppression should also be applied to the interconnecting wiring (data cables).

3.6 Parallel Connection
To reduce the wiring impedance to surge currents, it is recommended that the
phase, neutral (if required), and ground conductors are twisted together and
routed in the same raceway (conduit). Avoid any sharp bends in the conductors.
Tip: To maximize system performance, locate the unit as close as possible to the
protected circuit and keep interconnecting wiring less than 5 feet.
Wire Sizing: With parallel connection, the size of the wiring to the SPD unit is
independent of the protected circuit’s ampacity. For suggested wire size, refer to
Table 2.
NOTE: NEC Article 285-26 requires surge suppressor connecting conductors to
be at least #14 AWG copper or #12 AWG aluminum.
Overcurrent Protection: The SPD unit conducts minimal current under normal
operation and very short duration transient surge currents.
Disconnect Switch (if provided): All SPD units must be connected to the
load side of the main service disconnect or the load side of a protected circuit’s
disconnecting means.

3.7 Proper Connection of SPDs
Type1SPDsshallbeinstalledasdenedintheNationalElectricalCode(NEC)
2011 Edition as follows:
285.23 Type 1 SPDs (Surge Arresters). Type 1 SPDs shall be installed in accor-
dance with 285.23(A) and (B).

STV200/400KInstructionManual•9
A) Installation. Type 1 SPDs (surge arresters) shall be installed as follows:
1) Type 1 SPDs (surge arresters) shall be permitted to be connected to the
supply side of the service disconnect as permitted in 230.82(4) or
2) Type 1 SPDs (surge arresters) shall be permitted to be connected as
speciedin285.24.
B) At the Service. When installed at services, Type 1 SPDs shall be connected
to one of the following:
1) Grounded service conductor
2) Grounding electrode conductor
3) Grounding electrode for the service
4) Equipment grounding terminal in the service equipment
3.8 System Grounding & Bonding
The performance and safety of any SPD is dependent on proper grounding and
bonding. Grounding is required for safety; correct implementation also enhances
equipment performance. Incorrect grounding can reduce or impede the SPD’s
operation. All electrical circuits to the SPD must include an equipment-grounding
conductor as required by the NEC and local codes.
An insulated grounding conductor is required in addition to any metallic raceway,
which may be used as a grounding conductor. For parallel connected SPDs,
the grounding conductor should be the same wire size as the associated power
conductors. Grounding conductors must be routed with the associated power
conductors in the same raceway (conduit).
When metallic raceways are used, adequate electrical continuity must be
maintained at all raceway connections, particularly raceway terminations to the
electrical enclosures. The use of isolating bushings or other means to interrupt a
metallic conduit run is a potential safety hazard and is not recommended.
Grounding Electrode: Surge protective devices do not discharge all surges
to ground (earth). Surge protective devices divert the surge current back to its
source to complete the electrical circuit. In the case of lightning where potential
is developed with respect to the earth, the SPD diverts the surge current to the
grounding electrode (earth connection). However, for most transient surges that
are developed by switching loads, the SPD diverts the surge current back to its
source without involving the grounding electrode.
For proper SPD performance, the service entrance grounding electrode system
must comply with the NEC by having all available electrodes (building steel,
metal water pipe, driven rods, concrete encased electrodes, etc.) properly
bonded together and connected to the power system grounding. The use of a
separate grounding electrode to ground the SPD defeats the effectiveness of
the unit, is a potential safety hazard, may cause equipment damage, and is an
NEC violation (reference NEC 250.50).
System Neutral: For proper and safe operation, the neutral (if provided) must
be reliably connected to the neutral of the source. Failure to provide a reliable
neutral connection may result in SPD module failure.

STV200/400KInstructionManual•10
3.9 SPD Monitoring
External Status Indicators: These indicators provide a summary of the status of
the SPD module. For normal conditions, the green “OK” LED is illuminated and
the red “Service” LED is off. If the SPD module requires replacement, the green
“OK” LED is turned off and the red “Service” LED is illuminated.
Summary Alarm Contact: Summary alarm Form C relay contacts are provided
for remote indication of a failed SPD module. Contacts are rated 5 A at 250 V ac
maximumwithapowerfactorof1.0.Accesstothecontactsaretypicallyprovided
via contact terminals located on the printed circuit board (mounted on the inside
of the unit’s cover).
Transient Counter (optional): Transient counters are provided for transient
voltage surge monitoring. The counter totalizes surges monitored since the last
counter reset.
The transient counter monitors line transient voltages. The circuit counts all
surges that deviate from the line sine wave. The factory setting is 30% over
nominal line voltage. Other settings include 50%, 70%, and 100%.
Audible Alarm: If the SPD module requires replacement, an audible alarm is
activated. An audible alarm disable is provided to silence the alarm. The system
will automatically reset itself after repair. The audible alarm switch and “Service”
LED can be tested by activating the “Test” switch on the system monitor panel.
