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.
Installation Methods
(For the design engineer and the
installer)
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
disconnect switch.
End-use regulatory compliance is the responsibility of the end user.
Consult the factory for regulatory Conditions of Acceptability.

Plan Your Installation
Conductor Sizing and
Overcurrent Protection
✓
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.
Table 2: Maximum Recommended Conductor Size
Model Use conductor lengths
less than 10 feet
Max Torque
(in-lb)
ISM-050 #6 AWG45
ISM-080 #6 AWG45
ISM-100 #6 AWG45
ISM-125 #2 AWG50
ISM-150 #2 AWG50
ISM-200 #2 AWG50
ISM-250 #2 AWG50
ISM-300 #2 AWG50
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.
Page 10
CURRENT TECHNOLOGY® ISMTM INTEGRATED SUPPRESSION MODULE
W A R N I N G ! Prior to proceeding, ensure the SPD unit does not
have voltage applied to its input terminals.

Neutral to Ground Filter
Jumper
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.
Connector on ISM

Removal is accomplished by pulling the green jumper from the connector on
the ISM. Once removed, the jumper should be placed in the clear vinyl pocket
containing the unit test data for future use if desired (Figure 5).

For ISM mounting, refer to the appendix for detailed dimensional data.
Mounting
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
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.

➤ If your ISM has M1X Standard Monitoring (See Figure 6):
Verify Proper Operation
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
Figure 6
M1X Standard Monitoring
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.
