Surge Protective Device (SPD)

Installation, Operation

& Maintenance Manual

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

energy surge suppressor designed to protect sensitive equipment from damaging transient overvoltages.
SPDee 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.

SPDee 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.

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. DIN-Rail mounting may be handy.

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.

(long leads hurt performance substantially).

▪ 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 & 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).

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

2. Determine Mounting method (See Figure 5) – weather resistant equipment may be required.

3. If SPD has optional Dry Contact, pre-plan its installation.

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

5. Identify breaker location and SPD location. Position SPD such that LED is best visible.

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

- Remove an appropriately sized knockout from panel.

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

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 indicator and/or options.

(Afx supplemental label accessory if appropriate. See Figure 5.)

VERIFY THAT ALL POWER CIRCUITS ARE
DEENERGIZED BEFORE MAKING CONNECTIONS

All electrical connections should be performed by a qualied

(licensed) electrician or technician. All wiring must comply with
the National Electrical Code (NEC

WARNING

) and applicable local codes.

SPDee is a Type 1 SPD. SPDee is suitable for
use almost anywhere (not as a plug-in SPD).
Type 1 SPDs are evaluated more rigorously by
UL 1449 for NEC® 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 units are Type 2
due to different cUL criteria.)

Simplied 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.

Most SPDees have demonstrated 200kA &
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. SPDee is ultrasonically welded
closed and contains no user serviceable parts.

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 dened

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.
