HAZARDOUS VOLTAGES PRESENT: Improper installation or
misapplication may result in serious personal injury and/or damage
to electrical systems. Read the complete installation instructions
before proceeding with installation. Remove all power to the
electrical panel before installing or servicing the surge protective
device (SPD).
W A R N I N G !
IMPORTANT SAFETY INSTRUCTIONS: All work must be performed
by licensed and qualified personnel. The electrical system must be
properly grounded in accordance with the U.S. National Electrical
Code, state and local codes or other applicable codes for this SPD
to function properly. This device is suitable for installation where the
available short circuit current is 200,000 rms symmetrical amperes
at 600VAC or less.
tnbpowersolutions.com/current_technology
The ISM offers a full range of monitoring options when connected to an
optional monitoring package from the most sophisticated power quality
monitoring features offered in any surge suppression product. These features
include the following:
• Display of true RMS phase voltages
• Display of neutral-to-ground voltage
• Counting of swells, surges, sags and outages
• Display of percent available protection remaining
The Integrated Suppression Module incorporates individual thermally fused
and protected MOVs, thus preventing individual component failure from
rendering the protection mode useless. Instead, the failed component safely
removes itself from the circuit and all remaining protection is allowed to
continue operating as designed.

Discontinue installation if (1) your conditions are inconsistent with
the checklist above or (2) your conditions cannot be verified. Call
Thomas & Betts Power Solutions’ Technical Support at 800.238.5000
if you have any questions.
Check to ensure that a proper neutral-ground bond is installed between the
neutral and ground terminals at the transformer upstream from all 3-Phase
WYE, 3-Phase High-Leg DELTA, or 1-Phase SPLIT-PHASE ISM devices
(see NEC article 250.) Lack of a proper bond will damage the ISM and void
the warranty.
Confirm that the environmental conditions are consistent with the
following ranges:
• Ambient Temperatures: The ISM must be installed in an area with a
temperature between -40° and +140°F (-40° and +60°C).
• Humidity: The ISM must be installed in an area with relative humidity
between 5% and 95% non-condensing.
• Altitude: The ISM must be installed in a location where the altitude is
below 13,000 feet.
Pre-Installation Checklist ✓
This device features an internal protection that will disconnect the
surge protective component at the end of its useful life but will
maintain power to the load now unprotected. If this situation is
undesirable for the application, follow the manufacturer’s instructions
for replacing the device.
The ISM is a Type 4 component assembly which is suitable for use in both
Type 1 and Type 2 SPD applications. It may be installed on the line or load
side of the main service disconnect. The ISM 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 it is protecting. If direct bus connection
is used, Current Technology®
, recommends that the ISM be installed with a
disconnect switch.
End-use regulatory compliance is the responsibility of the end user.
Consult the factory for regulatory Conditions of Acceptability.

NOTE: Table 2 conductor sizing recommendations ensure that the effective
clamping voltage of the ISM at the point of connection is kept to a minimum
in order to maximize protection. Use solid or stranded copper or aluminum
conductor with strip length of 0.5".
Overcurrent Protection: When used as a Type 1 SPD, the ISM does not
require upstream over current protection for safe operation, however, the
design may require or the installer may choose to connect the ISM to a circuit
breaker, molded case switch or fused disconnect.
If a breaker or molded case switch is used for connecting the phase
conductors, Current Technology®recommends a 100 amp rating.
Table 2: Maximum Recommended Conductor Size
W A R N I N G ! The performance of the ISM will be severely
limited if the conductors are too long, are of too small a wire gauge,
have too many bends, or have sharp bends.
These factors should be addressed during the design of an installation to
ensure that there is a suitable place reserved for the stand-alone ISM next
to its point of connection to the panelboard it is protecting. The selected
mounting location should ensure short conductor runs and a minimum of
bends. If bends are required they should be sweeping bends. Do not make
sharp 90° bends for aesthetic purposes.
Conductor Length and Sizing: Conductor length must be kept as short as
possible and avoid sharp bends. The following conductor sizes for phase,
ground and neutral connections are recommended.

W A R N I N G ! Prior to proceeding, ensure the SPD unit does not
have voltage applied to its input terminals.
ISM models equipped with an EMI filter system (“-F” suffix), and have a
neutral connection, come with a green jumper wire that loops out of the
3-pin connector on the ISM and connects a filter neutral to ground. In certain
medical applications, or circuits which employ GFCI protection, this Neutral to
Ground filter connection should be removed.

For ISM mounting, refer to the appendix for detailed dimensional data.
This data is provided to aid in the design and fabrication of custom mounting
arrangements unique to each type of open frame installation.
The ISM is in a NEMA 1 enclosure which is suitable for indoor use only.
The ISM may be placed inside another enclosure to increase its protection
from environmental exposure. NEMA 4 enclosures are suitable for indoor or
outdoor use. NEMA 4X (plastic and stainless steel) enclosures are suitable
for corrosive environments as well. For direct sunlight applications, Current
Technology®suggests shading any optional monitoring components. All
conduits and fittings must be rated and properly installed such that the final
installation maintains the NEMA rating.
For systems requiring end-use regulatory compliance, Current Technology
recommends mounting the ISM inside a sturdy polymeric enclosure (0.125"
minimum thickness) or metal enclosure (min 15 gauge) with a minimum
clearance of 1/2" from any live electrical connection. End-use regulatory
compliance is the responsibility of the end-user.
Phases, Neutral* and Ground: Connect the phase, neutral and ground
conductors.
* DELTA-configured ISM models do not have a Neutral Lug.

CURRENT TECHNOLOGY®ISMTM INTEGRATED SUPPRESSION MODULE
➤If your ISM has M1X Standard Monitoring (See Figure 6):
Verify that only the green indicating lights are illuminated and that there are no
red lights illuminated. Green lights indicate a normal condition for each phase.
Orange lights indicate protection of 40–75% and Red lights indicate protection
of <40%. Three-phase units have three (3) green indicating lights labeled “A,”
“B,” and “C.” Split-phase units should only have lights “A” and “C” illuminated.
See table below for LED status indication.
The M1X Standard Monitoring is equipped with a dual set of Form “C”
dry contacts (Figure 6). The relay containing the contacts is in the “alarm
condition” or normally closed when the power is off to the unit, when the
unit is encountering loss of power to one or more phases, or the ISM is
encountering more than 40% loss of capacity due to internal fuse operation.
Test the operation of the Form “C” contacts by de-energizing the ISM and
checking the state of the contacts with a continuity tester or observing the
effect of the contacts on the user provided remote alarm circuits.
➤If your ISM has the M2X Option (See Figure 7):
The M2X option is equipped with a surge counter. The number of surges
detected by the ISM is displayed on a 6-digit LCD display on the front of the
counter. The surge counter will also increment each time power is applied to
the unit after being in the “off” state. The counter can be reset by pressing the
button on the front of the counter.
The M1X and M2X Standard Monitoring also contain an audible alarm that
should not operate under normal conditions. To silence audible alarm,
press ALARM SILENCE button on display.
