Surge Protective Device (SPD)

Installation, Operation

& Maintenance Manual

Thank you for choosing an APT XCS Surge Protective Device (SPD). The XCS is a high quality, high

energy surge suppressor designed to protect sensitive equipment from damaging transient overvoltages.
The XCS is parallel connected such that circuit ampacity is unlimited. Proper installation is important to
maximize performance. Please follow steps outlined herein. These instructions are not intended to replace
national or local codes. Follow all applicable electrical codes to ensure compliance.

UL 1449 Third Edition (Sept 2009) and 2008

WARNING

▪Only qualied licensed electricians should install or service SPDs
▪SPDs should never be installed or serviced when energized or during electrical storms
▪Use appropriate safety precautions including Personal Protection Equipment
▪Failure to follow these instructions can result in death, serious injury, and/or

equipment damage

▪When used in outdoor applications, customer must seal the conduit nipple using

watertight ttings (not included) to ensure a watertight connection

▪Read this manual in its entirety prior to installing

– Risk of Electric Shock

NEC

Article 285 generated substantial

changes regarding SPDs.

The X CS complies with latest regulatory
actions and is UL 1449 Listed as such
(VZCA.E321351). There is new emphasis on

installation location, identied as Types 1, 2,

3 and 4, outlined below.

SPD Types (see 2008 NEC® Article 285 and/or UL 1449-3):

Type 1: Installation on the line side or load side of the service

disconnect overcurrent device and may be used in Type 2 or Type
4 installations. Examples: surge arrestors, lightning arrestors,
meter hubs, metering cabinets, ran out of breaker positions, etc..
Type 2: Downstream of service disconnect; probably will
connect via breaker. Examples: switchboards, power panels,
panelboards, equipment, motors, pumps, etc.

Type 3: Plug-in SPD
Type 4:

Usually treated as a UL Recognized component in a larger

UL Listed nished product. Examples: UL 508 control panels, medical

equipment, wind turbines, signage, conveyers, elevators, etc.

INSTALLATION

Pre-Plan your installation. You need to accomplish the following:

▪ Meet all National and Local codes (NEC
▪ Conrm System voltage to SPD voltage (120V SPD will fail instantly on 240V, 277V, etc.).
▪ Mount SPD as close to panel or equipment as possible to keep leads short.
▪ Ensure leads are as short and straight as possible, including neutral and ground. If using a

breaker, use a breaker position that is close to the SPD and the panel’s neutral and ground.

▪ If using a breaker, recommended breaker size is 30A due to 10 AWG conductor.
▪ Make sure system is grounded per NEC

(inadvertent system problem may fail SPD).

▪ Never Hi-Pot test Any SPD. (will prematurely fail SPD).
▪ Do not install the XCS through the bottom of a NEMA 3R panel. Dripping water will

prematurely fail the SPD.

1. Use voltmeter to check voltages and ensure correct SPD. See Data Sheet for specs and wire-outs.

2. Determine Mounting location – weather resistant equipment may be required.

3. If SPD has optional Dry Contact Flush Mount Kit, or Remote Indicator, pre-plan their installation. See

Figure 3. (If ush mounting, be careful to not drop SPD into wall).

4. Remove power from panel/source. Conrm panel/source is deenergized.

5. Identify breaker location and SPD location. Position SPD such that LEDs are best visible.

6. Mount SPD – weather resistant applications require additional sealing, etc. (not included)

- Remove an appropriately sized knockout from panel.

- Connect conductors as appropriate – short and straight as possible (Hi-Legs are Phase B).

- Note that the metallic connection hub is not grounded within the SPD and proper grounding

requires connection of the green conductor ground.

7. Label or mark conductors as appropriate (neutral: white, ground: green, energized: black, hi-leg: orange).

8. Make sure system is bonded per NEC® and is clear of hazards or faults before energizing
(N-G bonding not per NEC® will fail SPDs: #1 cause of SPD failures).

9. Energize and conrm proper operation of green LED indicators and/or options.

®

Article 285 compliance. Type
1 SPDs and their connecting leads have been
evaluated for line side applications without need
for supplemental overcurrent protection. Type 1
SPDs include internal overcurrent protection. As
a generalization, there are practical maintenance
reasons for installing on the load side of the main
overcurrent device (i.e. Type 2 installation). When
connected on load side of main disconnect, we
recommend connecting via a 30A circuit breaker
due to 10 AWG conductors. The circuit breaker
serves as a disconnect switch and provides NEC®
imposed short circuit protection to the conductors
in Type 2 or 4 applications. (cUL models are Type
2 due to different cUL criteria.)

Simplified Explanation of Operation: SPDs
sense overvoltage and create a momentary short
circuit to redirect harmful surge energy to earth
ground. They reset automatically and wait for the
next surge. This is similar to the pressure relief
valve on a water heater: pressure goes up, valve
opens to relieve pressure and then resets. In an
electrical system, an SPD senses overvoltage,
shorts temporarily sending energy to ground and
then resets. SPDs are capable of repeating this
function thousands of times.

Voltage Rating & Application

Before installing SPD, verify by nameplate voltage
or model number that it has the same voltage rating
as the power distribution system. See attached Data
Sheet or call APT Tech Support at [phone]

as appropriate. The SPD’s specier or user should
be familiar with the conguration and arrangement

of the power distribution system. The system is
defined by how the secondary windings of the
transformer supplying the service entrance main or

load are congured. This includes whether or not

the transformer windings are referenced to earth via

a grounding conductor. The system conguration is
not based on how any specic load or equipment is

connected to a particular power distribution system.
SPDs should be installed per the distribution system,
not per a load or motor’s wiring connection.

For example, suppose a 480V three phase motor
appears to be connected as a 480V Delta. In
actuality, the serving distribution system might
be a 480Y/277V grounded Wye, with or without a
neutral pulled to the motor or MCC. The system
is still a 480Y/277V Wye, even though the load
is connected as a Delta. A grounded Wye has a

dened reference to ground (i.e., neutral is bonded

to ground). In contrast, some Delta systems are
ungrounded, which have no reference to ground.

Most XCS have demonstrated 200kA or 100kA
Short Circuit Current Ratings (SCCR) including
leads. See UL Label markings on SPD or see
Data Sheet for specs.) Supplemental overcurrent
protection is not required to protect this SPD.
However, NEC® convention requires that connecting
conductors have overcurrent protection in Type 2 or
4 applications. Follow applicable codes.

This device features internal overcurrent and
overtemperature protection that will disconnect
effected surge suppression components at the
end of their useful life, but will maintain power
to the load – now unprotected. If this situation
is undesirable for the application, follow these
instructions for replacing the device. XCS is
ultrasonically welded closed and contains no user
serviceable parts.
