Do not HIPOT the SPD unit or the electrical system to which
the SPD unit is connected without disconnecting the SPD
unit’s conductors, including phases, neutral and ground.
Ne procédez PAS à des ESSAIS DE RIGIDITÉ DIÉLECTRIQUE
sur le SPD ou le système électrique auquel il est connecté
sans déconnecter les conducteurs des SPD, y compris les
phases, le neutre et la terre.
WARNING
The SPD warranty is voided if the unit is damaged as a
result of improper installation. Improper installation or
misapplication may result in serious personal injury or
damage to the electrical system. Read the complete
installation instructions before proceeding with installation.
La garantie du SPD est annulée si l’appareil est endommagé à
la suite d’une mauvaise installation. Une mauvaise installation,
ou utilisation, peut entraîner des blessures graves ou des
dégâts au système électrique. Lisez les instructions
d’installation en intégralité avant de procéder à l’installation.
WARNING
The equipment covered by these instructions should be
installed and serviced only by competent qualified personnel
utilizing proper safety practices and procedures. These
instructions are written for such personnel and are not
intended as a substitute for adequate training and experience
in safe procedures for this type of equipment
L’équipement couvert par ces instructions doit être installé
et entretenu uniquement par un personnel compétent et
qualifié, utilisant des pratiques et des procédures de sécurité
appropriées. Ces instructions sont rédigées à l’intention de
ce personnel et ne sauraient se substituer à une formation
adéquate et à une expérience des procédures de sécurité
pour ce type d’équipement
WARNING
Remove all power to the electrical panel before installing or
servicing the SPD. All work must be performed by licensed
and qualified personnel. Follow applicable electrical codes
and regulations for the country/location in which the unit is
being used.
Coupez l’alimentation du panneau électrique avant d’installer
ou de procéder à l’entretien du SPD. Tous les travaux doivent
être effectués par un personnel qualifié et agréé. Respectez
les codes et réglementations électriques en vigueur dans le
pays / lieu où l’appareil est utilisé.
CAUTION
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.
Les réseaux électriques non mis à la terre sont
intrinsèquement instables et peuvent produire des tensions
ligne-terre excessivement élevées dans certaines conditions
de défaut. Dans ces conditions de défaut, tout équipement
électrique, y compris un SPD, peut être soumis à des tensions
qui dépassent les valeurs nominales prévues. Cette
information est fournie à l’utilisateur afin qu’il puisse prendre
une décision réfléchie avant d’installer un équipement
électrique sur un réseau électrique non mis à la terre.

2OVRHTP SERIES SPDS

WARNING
Check to ensure that a proper bond is installed between
neutral and ground at the transformer upstream from all
3-phase wye, 3-phase high-leg or 2-phase SPD devices. If
the transformer is not accessible, check the main service
disconnect/panel for the NG bond. Lack of a proper bond may
damage the SPD and void the warranty. Failure to provide this
bond, as required per article 250.30 of the National Electrical
Code, can result in elevated phase-to-ground source voltage
potentials. These voltages can cause damage to electrical
equipment as well as safety hazards including fire, electrical
shock, serious injury or death.
Vérifiez qu’une liaison correcte est installée entre le neutre et
la terre au niveau du transformateur en amont de tous les SPD
triphasés en étoile, triphasés en triangle ou biphasés. Si le
transformateur n’est pas accessible, vérifiez la liaison NG sur
le sectionneur / panneau de service principal. L’absence d’une
liaison appropriée peut endommager le SPD et annuler la
garantie. L’absence de cette liaison, telle que requise par
l’article 250.30 du Code national de l’électricité, peut entraîner
des potentiels de tension élevés entre la phase et la terre. Ces
tensions peuvent causer des dégâts aux équipements
électriques ainsi que des risques en matière de sécurité,
notamment des incendies, des chocs électriques, des
blessures graves ou la mort.
WARNING

6OVRHTP SERIES SPDS

NOTICE
The SPD unit’s performance will be degraded if the
conductors are (a) too long, (b) are of too small a wire
gauge, (c) have too many bends or (d) have sharp bends.
Les performances du SPD seront dégradées si les
conducteurs sont (a) trop longs, (b) d’un calibre de fil
trop faible, (c) présentent trop de courbures ou (d) ont
des courbures trop prononcées.
The factors listed above should be addressed during the
design of an installation to reserve a suitable place for
the OVRHTP series unit next to its point of connection
to the electrical system. The selected mounting location
should allow for the shortest possible conductor runs
and a direct route with a minimum of bends. If bends are
required, they should be sweeping bends. Do not make
sharp 90° bends for appearance purposes because
they will decrease the effectiveness of the OVRHTP
series unit.
Binding or twisting conductors together using cable
ties or electrical tape improves the protection
performance of the device.

The OVRHTP series unit is a one-port SPD and is to be connected in
parallel with the electrical system. It may be connected via a circuit
breaker, molded case switch, fused switch, or connected directly to
the bus of the panelboard or switchboard (local and national electric
codes take precedence). If direct bus connection is used, ABB
recommends installing the OVRHTP series unit behind a disconnect

assumed that the facing layer of wall board has not been
installed yet.
First, the enclosure should be mounted to the rear wall or
studs with the appropriate hardware. It should be positioned
so that when the next steps are followed, the enclosure will
project through the wall by the desired amount. Next, the
wall board should be installed. The wall board should
be installed over the SPD, so that the SPD projects through
the wall board.
CAUTION
If the SPD has become energized, it must be de-energized
now. Appropriate high voltage safety procedures should be
followed here.
The lid of the enclosure must be unscrewed. It is generally not
necessary to disconnect the monitor cables from the lid. It is
permissible to allow the lid dangle on its ground lead, so long
as the lid is gently lowered into place. The lid should be
maneuvered through the rectangular hole in the wall board.
The flush-mount plate (FMP) is placed over the SPD enclosure.
Mark the mounting hole locations through the 4 holes in the
FMP. Remove the FMP. Drill holes at the marked locations.
(These should be wide enough for the wall anchors to fit
snugly.) Push the wall anchors into the holes. Tighten the
screws that were in the wall anchors, until the wall anchors
expand against the wall board. Remove and discard the 4
screws. (The anchors will remain in place.) Place the FMP over
the SPD enclosure again. Fasten the FMP to the anchors with
the (nicer looking) truss mount screws. Fasten the lid back
onto the enclosure body. When fastening the lid, be careful
that cables do not get pinched! Now, power may be restored
to the SPD.

Connecting form C dry contacts
Units supplied with form C dry relay contact provide the
means for customer-supplied remote status indication
that operates in tandem with the SPD’s inherent LED status
indication. These contacts are for connection to a user-
provided remote alarm and monitoring circuit. The relay
contacts are rated maximum 1 A/30 V DC, 6 A/125 V AC.
The form C contacts come pre-wired with 914 mm (36 in.)
of #20 AWG conductors.
When input power is present on all phases, terminals “NO”
black (normally open) and “COM” white (common) are an open
circuit, and terminals “NC” red (normally closed) and “COM”
are a closed circuit. The contacts change state when the unit
has encountered failure to one or more phases.
The installer must provide the appropriate raceway and wiring
for the monitoring circuit, observing the restrictions and
conduit openings illustrated in an earlier section of this
manual.
Use butt splices within the panelboard to connect the form C
leads to the user’s monitoring circuits. Alternatively, install a
junction box between the OVRHTP series and the panelboard
to connect form C leads to user’s monitoring circuits. If the
form C contacts are not used, user has the option of either
cutting off the leads or coiling up the leads. Consult applicable
local codes to ensure proper installation.
For these models, the form C contacts must be wired
by the installer.
See terminal block cover rear view diagram for the form C
contact configuration and terminal location on the monitor
board. The annotations on the diagram match the markings
on the terminal block.
The installer must route the monitoring conductors to the
terminal blocks on the main monitoring board. Tighten screws
on terminals to 0.4 Nm (3.5 in-lb). This terminal block will

Verification and power up
WARNING
The cover of the OVRHTP series unit along with its associated
cabling must be installed prior to applying power. The
monitoring harness contains line voltage when power is
applied to the unit.
Le couvercle du parafoudre et le câblage associé doivent
être installés avant la mise sous tension. Le faisceau de
surveillance contient la tension de ligne lors de la mise
sous tension de l’unité.
Apply power to the SPD by closing the OCPD or switch feeding
the suppressor.
Mettez sous tension le parafoudre en fermant le dispositif
de protection contre les surintensités ou l’interrupteur qui
alimente le parasurtenseur.
Upon energization of the SPD, if any of the LED(s) or alarms
indicates an abnormal condition, power should promptly be
disconnected from the SPD. The electrical system should be
inspected and the pre-installation requirements should be
validated. Do not attempt to leave power applied to the SPD,
or re-energize the SPD in the event of an alarm condition.
Please contact your local ABB representative for further
assistance.
Lors de la mise sous tension du parafoudre, si l’une des LED
ou des alarmes indique une anomalie, l’alimentation doit être
rapidement déconnectée du parafoudre. Le système électrique
doit être inspecté et les exigences préalables à l’installation
doivent être validées. N’essayez pas de laisser le parafoudre
sous tension ou de le remettre sous tension en cas d’alarme.
Veuillez contacter votre représentant ABB local pour obtenir
de l’aide.
Standard monitoring package
Verify that the indicating LED(s) are illuminated. The indicating
lights extinguish only upon failure of one or more phases
(indicating an alarm condition).
Advanced monitoring package
Verify that aII “phase protection status”indicating lights are
illuminated. The “service required”indicating light illuminates
only upon failure of one or more phases. Audible alarm should
not operate under normal conditions. The audible alarm can
be “muted”by pressing the “alarm ON/OFF”button, which
subsequently will illuminate the “alarm silenced”light.
Pressing the “alarm ON/OFF”button again will enable
the alarm.
Units with surge counter
The number of surges detected by the SPD is displayed on
an eight-digit LCD display on the front of the door. The LCD
counter is battery backed to maintain the number of surges
even during a power loss. Press the button on the lid to reset
the surge count.
NOTICE
Pressing the “Alarm ON/OFF” button when the alarm has not
triggered will prevent the audible alarm from sounding during
a failure.
En appuyant sur le bouton « Alarm ON/OFF » lorsque l’alarme
ne s’est pas déclenchée, vous empêchez l’alarme sonore de
retentir en cas de panne.
