Surge Protection Device for AC Power Applications

2
The ADSx Series of AC Surge Protection Devices are ANSI/UL 1449 -3rd
Edition dened as Type 1/2 protective devices. Type 1 SPDs are suitable for
direct installation on the supply line of the service disconnect. Type 2 SPDs
are installed on the load side of the service disconnect and may be ordered
with UL1283 Listed EMI/RFI lter.
The SPDs are parallel mounted transient surge suppression devices
intended to be installed either at an AC Main Service, Distribution Panel
or a critical load. They may also be mounted directly within equipment
enclosures such as SCADA Control Panel Systems.
The SPD should be part of a coordinated surge suppression system that
includes primary protection at the main service entrance, secondary
protection at distribution panels, and at point of use for sensitive electronic
equipment. Proper system design should also include protecting all other
copper data lines or control signals that leave or enter the equipment site
building.

General Safety
This document provides detailed information on how to install and operate
the ADSx Series of Surge Protection Devices (SPDs).
IMPORTANT
INSTALLATION OF THIS DEVICE SHOULD ONLY BE PERFORMED BY A
LICENSED ELECTRICIAN.
Incorrect installation may signicantly impair the performance of this Surge
Protection Device. All installation procedures and guidelines MUST be followed
exactly.
Before starting any installation procedures:
1. Verify service voltage conguration with an AC voltmeter to ensure that
the correct SPD model has been selected.
2. Verify Earth Ground resistance is less than 25 ohms.
3. Secure all power from the panel to which the devices is being installed.
Failure to do so could result in damage to the suppressor and poses a
potential electrical shock hazard to personnel.
4. Ensure all connections are correct per the layout installation diagram
(See Fig. 4) and secure before energizing SPD.

UNPACKING
Unpack the surge suppressor from its shipping container and visually
inspect for shipping related damage. If unit(s) are received damaged, notify
the shipping company immediately. Retain all shipping containers and
packing materials for inspection.
LOCATION CONSIDERATIONS
Select a location as close as possible to the AC power source and securely
mount it to any surface. Route conduit from the AC power source to
the suppressor assembly. The unit is designed for indoor and outdoor
installations in ambient temperatures of -40°C (-40°F) to +60°C (140°F) with
a relative humidity of 0% to 95% (non-condensing). It is encouraged to
avoid direct sun loading.
OVERCURRENT PROTECTION
For ease of maintenance, it is recommended that the SPD be connected to
the service panel using a multi-pole 20 A or 30 A circuit breaker.
MOUNTING
The SPD uses a NEMA 4X enclosure, suitable for use in indoor or outdoor
installations. Locate the SPD on the wall next to the service panel. Locate
the available disconnect means and remove the closest knockout. If the
SPD shall be connected to the knockout via conduit, plan the route to
minimize bends and wire lengths. The conduit needs to match the Type
rating of the enclosure (Type 4X), unless installed in dry indoor location.
Refer to the dimensional information for mounting hole dimensions,
clearances and weight. Mount SPD to wall using 3/8” mounting hardware.

Mounting Instructions
Optimize device performance by keeping connecting wires as short and
straight as possible.
1. Plan the wiring path(s) prior to commencing the installation procedure.
2. Locate the SPD as close to the available disconnecting means to
minimize the length of the connecting wires.
3. Securely mount the SPD unit using the four (4) mounting holes provided
in the enclosure’s mounting anges.
The ADSx Series products are installed and connected in parallel “shunt”
across the AC supply to be protected. Connecting wires do not carry the
supply current. They only conduct the short duration current associated with
the suppression of transient surge events.
Installation Instructions
Before starting the installation, measure the Line voltage with an AC
voltmeter to ensure the correct device has been selected for the current
application. The MCOV (maximum continuous operating voltage) must not
exceed the maximum limits for the following service voltages:
120 Vac = 180 MCOV 277 Vac = 320 MCOV
127 Vac = 180 MCOV 480 Vac = 550 MCOV
220 Vac = 320 MCOV 600 Vac = 690 MCOV
240 Vac = 320 MCOV

ELECTRICAL CONNECTIONS
Ensure that all power is removed before beginning installation. Verify that
the voltage rating is appropriate for connection to the intended power
source. Connect the green/yellow Ground wire and the white neutral wire.
Then connect the black (phase A), Red (phase B), and Blue (phase C) wires,
keeping all conductors as short and straight as possible, ideally less than 18
inches. The grounding conductor should be the same size as the associated
power conductors. Grounding and power conductors should be routed in
the same conduit. If metallic conduit is used, adequate electrical continuity
must be maintained at all connections, including electrical enclosures.

SYSTEM GROUNDING AND BONDING
For proper SPD performance, the service entrance grounding electrode
system must comply with the NEC (National Electric Code) by having all
available electrodes properly bonded together and connected to the power
system grounding (building steel, driven rods, concrete encased electrode).
For optimum SPD performance, an earth ground resistance of < 5 Ohms
is recommended. See NEC table 250-122 for the appropriate grounding
conductor size.
ALARM CONTACTS
If desired, connect the SPD summary alarm contacts.
1. Loosen screws on front of unit, remove cover and turn over.
2. Locate the terminal connections and connect using #18 - #22 AWG
wires. Route wires out thru pipe nipple.
3. Close cover taking care not to pinch any wires or ribbon cable.
4. Tighten screws.
Wiring for the Alarm Contacts must meet or exceed the rating of the wiring
provided for the mains.
OPTIONAL INSTALLATION:
1. It is possible for an end-user to add their own nipple to the bottom of
the enclosure, so the Alarm Contact wiring can be brought straight out.
2. The nipple needs to match the Type rating of the enclosure (either Type
4 or 4X), unless installed in dry indoor location.
3. The alarm contact wiring ratings need to be suitable for the voltage and
current available at the alarm contacts.

Wiring Instructions
1. Connect the Green/Yellow Ground wire to the system ground bus.
2. Connect the White Neutral wire to the neutral bus.
3. Connect the Black (phase A), Red (phase B), and Blue (phase C) wires
to each phase.
4. Apply external AC power to the SPD, check that Blue LEDs are
illuminated per the diagrams below.

NOTE:
BEFORE ENERGIZING THE SPD: ENSURE ALL CONNECTIONS ARE CORRECT.
STATUS INDICATORS - PHASE LED INDICATOR(S)
When the SPD is securely connected and operating properly, the Blue
Phase LEDs will be illuminated. Replacement of the SPD is required if any
Blue phase LED is not illuminated.
Apply power. The SPD is fully operational when the BLUE LED on the front
panel are illuminated. If the Blue LED are extinguished, check to ensure
power is applied. If the alarm contacts indicate an abnormal condition
exists, remove power and contact ALLTEC customer service at 1-800-203-
2658 or www.alltecglobal.com.
