OVRHT3D
Surge protective device (SPD)
• This manual shall be read in its entirety prior to installing.
• Failure to follow these instructions can result in death, serious injury
and/or equipment damage.
• SPD should be installed by a qualified electrician in accordance with
national and local electrical codes.
• Use appropriate safety precautions including personal protection
equipment.
• Cannot be used on ungrounded systems.
• The voltage rating of the SPD and system must be verified before
energizing the SPD.
• Hazardous voltages exist within SPDs when energized — SPDs should
never be installed or serviced when energized. During installation into
an electrical system, the SPD must not be energized until the electrical
system is completely installed, inspected and tested.
• Do not HIPOT the SPD unit or the electrical system in which the SPD
unit is connected without disconnecting the SPD unit’s conductors,
including phase, neutral and ground.
Installation
OVRHT3D units are Type 1 and do not require upstream overcurrent
protection for safe operation; however, the design may require or the
installer may choose to connect the OVRHT3D to a circuit breaker,
molded case switch or fused disconnect. If a breaker or molded case
switch is used for connecting the phase conductors, a 20–30 A breaker
is recommended. The unit must be installed in parallel to the electrical
distribution system. Careful consideration should be made in selecting
the knockout location. The SPD’s performance will be limited severely 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. Meet all national and local
codes. (NEC Article 242 addresses SPDs.) Do not splice SPD conductors
within the unit’s enclosure or manufacturer’s warranty will be void.
1. Prior to installation, ensure the system configuration and voltage
is equivalent to the SPD unit being installed.
2. Disconnect power to electrical panel. Use voltmeter to confirm
disconnection.
3. Remove the panel screws and cover. Retain these parts
for re-installation.
4. Remove appropriate sized knockout.
5. Mount SPD. Connect to equipment using an approved wiring method,
including seals appropriate for the enclosure rating.
6. Connect the white or blue wire to the neutral bar and tighten to
torque specified on inside of panel. Keep conductor length as short
as possible and avoid sharp bends.
7. Connect the green/yellow wire to the ground bar and tighten the
terminal to the torque specified inside of panel. Keep conductor
length as short as possible and avoid sharp bends. If neutral is bonded
to ground, green wire may be terminated to neutral.
8. Connect black or brown wires (model dependent) to the breaker or
the bus of the panel. Ensure the short circuit current rating does not
exceed 65, 100 or 200 kAIC. On High-Leg Delta units, connect the
orange wire to phase B (the high-leg). If the ability to turn off the unit
is desired, consider connecting it to a breaker (number of breaker pole
positions determined by the number of black or brown wires provided
with the unit). Tighten terminals to torque specified on inside of
panel. Keep lead lengths as short as possible and avoid sharp bends.
9. Re-install panel cover.
Operation
1. Apply power to the panel. If the phase, neutral and ground have been
wired correctly, the green function status LEDs will illuminate. If the
LEDs do not turn on, remove the power and review all of the previous
installation procedures.
2. If the LED light(s) does not illuminate and the SPD is tied to a breaker,
reset the breaker. If the LED light(s) illuminates after reset, the device
is ready for operation. If the LED does not illuminate after reset, or the
breaker will not reset, SPD must be replaced.
This unit contains no serviceable parts.
These instructions do no purport to cover all details for variations
in equipment nor to provide for every possible contingency.
Warranty
ABB warrants that Equipment (excluding Software) shall be delivered
free of defects in material and workmanship. The Warranty Remedy
Period for Equipment (excluding Software) shall end three (3) years after
the original date of purchase. If a nonconformity to the foregoing
warranty is discovered in the Equipment during the applicable Warranty
Remedy Period, as specified above, under normal and proper use and
provided the Equipment has been properly stored, installed, operated
and maintained and written notice of such nonconformity is provided to
ABB promptly after such discovery and within the applicable Warranty
Remedy Period, ABB shall, at its option, either (i) repair or replace the
nonconforming portion of the Equipment or (ii) refund the portion of
the price applicable to the nonconforming portion of Equipment. If any
portion of the Equipment so repaired or replaced fails to conform to
the foregoing warranty, and written notice of such nonconformity is
provided to ABB promptly after discovery and within the original
Warranty Remedy Period applicable to such Equipment or 30 days from
completion of such repair, replacement or re-performance, whichever
is later, ABB will repair or replace such nonconforming Equipment. The
original Warranty Remedy Period shall not otherwise be extended.
ABB shall not be responsible for providing temporary power, removal,
installation, reimbursement for labor costs or working access to the
nonconforming Equipment, including disassembly and reassembly of
non-ABB supplied equipment, or for providing transportation to or from
any repair facility, or for any other expenses incurred in connection with
the repair or replacement, all of which shall be at Purchaser's risk and
expense. ABB shall have no obligation hereunder with respect to any
Equipment which (i) has been improperly repaired or altered; (ii) has
been subjected to misuse, negligence or accident; (iii) has been used
in a manner contrary to ABB's instructions; (iv) is comprised of materials
provided by or a design specified by Purchaser; or (v) has failed as a
result of ordinary wear and tear. Equipment supplied by ABB but
manufactured by others is warranted only to the extent of the
manufacturer’s warranty, and only the remedies, if any, provided by
the manufacturer will be allowed. Software Warranty and Remedies.
ABB warrants that, except as specified below, the Software will, when
properly installed, execute in accordance with ABBʼs published
specification. If a nonconformity to the foregoing warranty is
discovered during the period ending one (1) year after the date of
shipment and written notice of such nonconformity is provided to
ABB promptly after such discovery and within that period, including a
description of the nonconformity and complete information about the
manner of its discovery, ABB shall correct the nonconformity by, at its
option, either (i) modifying or making available to the Purchaser
