BEFORE INSTALLATION
!
!
WARNING: HAZARDOUS VOLTAGES PRESENT Improper installation or misapplication may result in
serious personnel injury and/or damage to electrical system. 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).
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. The LowProfile (LP), as a Type 1 SPD
can be connected to the line side of the main service breaker or disconnecting means. This device is suitable
for installation where the available short circuit current is 200,000 rms symmetrical amperes at 600VAC or less.
1. System Configuration Verification
Confirm that the voltage(s) and service configuration shown on the LowProfile product label are consistent with the voltage
and service configuration of the facility. A model number is on the left side of the LowProfile unit. Each model number
corresponds to the configurations printed in the table below:
Example of LowProfile model number: TK-LP080-3Y208-FL

upstream from all 3-phase WYE or split-phase LowProfile SPD (See NEC Article 250). If the transformer is not
accessible, check the main service disconnect/panel for the N-G bond. Lack of a proper bond will damage
LowProfile and void the warranty.
2. Wiring Connection Diagrams
Figure 3 shows the electrical relationship between LowProfile and these three basic service configurations:
Split phase, 3-wire, Three-phase, 4-wire WYE, and Three-phase, 4-wire high-leg Delta.
Fig. 1: Split Phase, 3-Wire
SPD
Connections to the SPD are clearly identified. Connections are made via pigtail leads supplied with the unit. For 3 phase
units phases A, B and C are black wires, which are marked “Phase A”, “Phase B” and “Phase C” respectively. For split phase
units, the phase connections are marked “Phase A” and “Phase B”. The neutral is a white wire and the ground is a
green/yellow wire.
3. Upstream Over-Current Protection Devices
The LowProfile has been listed to UL1449 as a Type 1 SPD. Type 1 SPDs can be used in Type 1 or Type 2 SPD applications,
which means that the LowProfile does not need to be connected behind an upstream over current protection device and can
be connected on either the line or load side of the main service disconnect. The LowProfile must be connnected in parallel
with the electrical system. All LowProfile units come standard with component-level over-current fusing rated at 200,000 rms
symmetrical amperes at 600VAC.

CAUTION: Do not splice Low Profile conductorswithin the unit’s enclosures or Manufacturer’s warranty will
be void. LowProfile’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.
4. Conductor Routing
The factors listed above should be addressed during the design of an installation to reserve a suitable place for LowProfile
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 severely decrease the effectiveness of LowProfile.
Braiding or twisting conductors together using tie-wraps or electrical tape increases the protection performance of the device.
One or two twists or braids of all conductors per foot and securely tie-wrap when conductor lengths must exceed 12”.
5. Conduit Openings
All LP units come with a 3/4” conduit hub and chase nipple. There are three conduit openings located in top, top left, and
top right sides of the enclosure. The hub can be installed in any of the three openings. The remaining unused openings can
be covered with supplied knock-out seals.

Enclosure Mounting,
and Dimensions
6. Mounting
LowProfile can be mounted in a variety of methods. The basic method is to wall mount using the mounting feet attached
to the base of the enclosure. LowProfile can also be mounted even (or flush-mount) to the exterior wall surface. Mount
LowProfile using construction methods and hardware appropriate for your site. Install the conduit hub, chase nipple and
pull conductors as specified above or according to the engineer’s design. See Figure 3 for enclosure and mounting
dimensions.
7. Optional Flush-Mount Plate
Optional flush-mount plate, part number LP-FMP, can be purchased for flush-mount installation. Typically a cutout, larger
than the LowProfile enclosure, is created in the drywall or other finish material. See Figure 4 for the recommended cutout
gap (dimensions L1 and L2). Use the flush-mount plate to hide the gap between the enclosure and the cutout edges. Prior
to installation, attach the plate to the enclosure using the existing cover screws.

CONNECTION AND WIRING INSTRUCTIONS
!
1. Phase, Neutral, and Ground Connections
NOTE: In order to connect the LowProfile unit, it will be necessary to remove the cover of the unit. Use care when removing
the cover, as there are wires, which run from components on the cover to inside the enclosure of the SPD. The monitor
board (located on the backside of the cover) has a cable harness which routes into the enclosure.
CAUTION: Prior to installation ensure the system configuration and voltage is equivalent to the LowProfile
unit being installed.
Following all applicable National Electrical Code standards as well as state and local codes, connect phase, neutral and
ground to LowProfile. If suppressor is being installed on a breaker, installation electrician should install device directly adjacent to the breaker feeding the device to insure conductor length is kept to a minimum. The 80ka and 120ka are supplied
with #10 AWG conductors permanently attached. should mounting conditions require extension of the supplied
conductor(s), installation electrician may use a butt-splice or parallel solder with shrink-tube insulation. In no event shall
the electrician use a wire nut to make the extension as this will result in loss of suppressor performance. Ensure that the
conductor lengths are kept as short and straight as possible. On all high-leg systems, the phase B conductor of the suppressor (color-coded orange according to NEC) must be connected to the high-leg.
Install SPD directly adjacent to the point of termination
to insure conductor length is as short as possible
for optimum performance and protection.
2. Connecting Form C Dry Contacts
All LowProfile units come standard with one set of Form “C” dry relay contacts for the SPD status. These contacts are for
connection to a user-provided remote alarm and monitoring circuit. The relay contacts are rated 65VDC/150VAC with maximum switching power of 30WDC/60VA AC. See Figure 5 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.
When input power is present on all phases, terminals “NO” and “COM” are an open circuit and terminals “NC” 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. The installer must route the monitoring conductors to
the terminal blocks on the lid-mounted main monitoring board. Route the wires to allow the lid to be opened and closed
properly. Tighten screws on terminals to 3.5 in-lbs (0.4 Nm). This terminal block will accept wire sizes #28AWG to #16AWG.
#18AWG to #20AWG is recommended.

3. Neutral to Ground Filter Jumper
All LowProfile models with enhanced filter (model numbers end with “-F” suffix) come with a green jumper wire, which
loops out of the epoxy and connects the filter from neutral to ground. In certain medical applications or circuits which
employ GFCI protection, this Neutral to Ground filter connection should be removed.
WARNING: Prior to proceeding, ensure the LowProfile unit does not have voltage applied to its input
terminals
Removal is accomplished by cutting the green jumper wire. Once cut, both ends should be properly separated and insulated
to prevent the ends from making inadvertent electrical contact.

4. Verification and Power Up
R
R
!
WARNING: It is recommended that the cover of the LowProfile unit along with its associated cabling be
installed prior to applying power. The monitoring harness, which exits the epoxy and connects to J2 on the
monitor board, contains line voltage when power is applied to the unit.
Apply power to LowProfile by closing the switch feeding the SPD.
Verify that all “Phase Protection Status” indicating lights are illuminated. The “Check System” indicating light illuminates
only upon failure of one or more phases (indicating an alarm condition). Audible alarm should not operate under normal
conditions. The audible alarm can be “muted” by pressing the “ALARM SILENCE” button, which subsequently will illuminate
the “ALARM SILENCED” light. Pressing the “ALARM SILENCE” button again will enable the alarm.
