JOSLYN®JSPTM, JSPR INSTALLATION, OPERATION AND MAINTENANCE MANUAL
W A R N I N G !
THE JSP SERIES WARRANTY IS VOIDED if the unit is damaged as a
result of improper installation or the installer’s failure to verify the
following conditions prior to installation.
W A R N I N G !
HAZARDOUS VOLTAGES PRESENT: 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. Remove all power to the electrical panel
before installing or servicing the 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
up to 600VAC or less. For countries outside of the US follow applicable
electrical specifications for the country the unit is being used in.
W A R N I N G !
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 Delta or Split-Phase JSP Series device (See NEC Article 250).
If the transformer is not accessible, check the main service
disconnect/panel for the NG bond. Lack of a proper bond will
damage JSP Series and void the warranty.
W A R N I N G !
Do not HIPOT the JSP Series units or the electrical system to which
the JSP Series unit is connected without disconnecting the JSP Series
units conductors including phases, neutral and ground.
Guide to Installation and Assistance Thank you for choosing the Joslyn® JSPTM Series Surge Protective Device (SPD).
We look forward to fulfilling your facilitywide surge protection needs.
Should you have questions about installing the JSP Series please
call Joslyn®Technical Support at 800.238.5000 or 804.236.3300
Monday through Friday, 8:00 a.m. to 5 p.m. (EST). Or, email us at
[email protected].
This manual provides guidelines for the proper installation of the JSP Series
of devices. Proper product selection and compliance with these guidelines
will help your new suppression system provide years of reliable service. If
installers are unsure about the facility electrical configuration or have other
installation-related questions, it is recommended they consult with a master
electrician or other qualified electrical professional.
When shortcuts are taken or installation procedures are not followed, the
JSP Series may become damaged or may not provide adequate protection. It
is extremely important to follow these installation procedures carefully.

CAUTION: The JSP Series unit’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. For optimum
performance never exceed 10' conductor lengths.
The factors listed above should be addressed during the design of an
installation to reserve a suitable place for the JSP 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
severely decrease the effectiveness of JSP Series unit.
Binding or twisting conductors together using tie-wraps or electrical tape
increases the protection performance of the device.
The conductor length should be as short as possible to ensure the maximum
level of protection. Wires are marked with (Phase A, B, C, Line 1, Line 2,
Neutral or Ground) depending on the model.

Upstream Overcurrent
Protection Device
Joslyn recommends installing the JSP unit by following conductor size for
phase, ground and neutral connections. The conductor length should be as
short as possible to ensure the maximum level of protection.
Table 2: Maximum Recommended Conductor Size
The JSP Series unit is a Type 1 SPD which is suitable for use in both Type 1
and Type 2 SPD applications. The JSP 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 it is protecting. If direct bus
connection is used, Joslyn®recommends installing the JSP Series unit behind
a disconnect switch or other disconnecting means for ease of serviceability.
If the SPD is connected to a dedicated OCPD, a 60A breaker is recommended
(30A minimum, 200A maximum).

• 60 through 100kA units are shipped with #10AWG leads. Leads should be
shortened during installation in order to minimize conductor length.
• 120 through 400kA units are shipped with compression box lugs.
The set screws on the box lugs should be torqued to 20 in-lbs.
• Terminals are identified with markers (Phase A, B, C, Line 1, Line 2,
Neutral or Ground)

Mounting
(JSPR)
Indoor vs. Outdoor Installations
Mount the JSP to the building structure using construction methods and
hardware appropriate for your site. Install the conduit and pull the conductors
as specified in Table 2.
Mount the JSPR to the building structure using construction methods and
hardware appropriate for your site.
Mount the JSPR into the wall. Electrician can mount to the back wall, if the
back wall is made of structural material such as masonry or plywood. (Drywall
is not a structural material). If back wall is not made of structural material, the
electrician can create brackets to hold the SPD to the adjacent studs.
After the drywall has been installed, install Flush Mounting Plate (FMP) by first
removing the JSPR enclosure lid. Place the FMP over enclosed body. Attached
the FMP to the wall using the enclosed hardware kit. Screw the lid back on to
the enclosure body.

NEMA 4 enclosures are suitable for indoor or outdoor use. NEMA 4X (stainless
steel) enclosures are suitable for corrosive environments as well. For direct
sunlight applications, Joslyn suggests shading the monitoring components.
All conduits and fittings must be rated and properly installed so that the final
installation maintains the NEMA rating.
If desired, punch holes at this time for the conduit or nipple or wait until
the JSP unit is mounted to the building structure. Punch holes only in the
designated areas as shown in the following illustration.

JOSLYN®JSPTM, JSPR INSTALLATION, OPERATION AND MAINTENANCE MANUAL
CAUTION: Careful consideration must be made when selecting
an area for conduit entry. There are several components inside the
enclosure that may interfere with the conduit entry path, therefore,
ensure the path is clear of all objects before drilling. Damages caused
by installation errors are not covered under the product warranty.
See Figures 6A and 6B for conduit openings and enclosure dimensions.

CAUTION: Prior to installation ensure the system configuration and
voltage is equivalent to the JSP Series unit being installed.
Electrical Connections
Following all applicable National Electrical Code standards as well as state and
local codes, connect phase, neutral* (white wires) and ground (green wires) to
the JSP Series unit.
JSPR units come with 36" of #10AWG conductors. Each phase conductor is
labeled (Phase A, B or C). Ensure that the conductor lengths are kept as short
and straight as possible. On all high-leg delta systems, the high-leg (208V LN)
must be connected to the Phase B of the SPD. (Color coded orange according
to NEC).
*The 3-Wire + Ground Delta JSP Series units do not have a neutral conductor.
