familiar with the device before trying to install, operate, service or maintain it.
The following special messages may appear throughout thisbulletin or on the
equipment to warn of potential hazards or to call attention to information that
clarifies or simplifies a procedure.
The addition of either symbol to a “Danger”or “Warning” safety label
indicates that an electrical hazard exists which will result inpersonal
injury if the instructions are not followed.
This is the safety alert symbol. It is used to alert you to potential
personal injury hazards. Obey all safety messagesthat follow this
symbol to avoid possible injury or death.
DANGER
DANGER indicates a hazardous situation which, if not avoided,
will result in death or serious injury.
WARNING
WARNING indicates a hazardous situation which, if not avoided,
could result in death or serious injury.
CAUTION
CAUTION indicates a hazardous situation which, if not avoided,
could result in minor or moderateinjury.
NOTICE
NOTICE is used to address practices not related to physical injury. The safety
alert symbol shall not be used with this signal word.
Please Note
Electrical equipment should be installed, operated, serviced, and maintained only
by qualified personnel. No responsibility is assumed by ASCO Power Technologies
for any consequences arising out of the use of this material.
A qualified person is one who has skills and knowledge related to the

ASCO 330 Surge Protective Device (SPD)
Installation Manual
Introduction The ASCO Model 330 Surge Protective Device is a high quality, high energy
surge current diversion system designed for use with equipment that is
sensitive to damaging transient voltage surges.
HAZARD OF ELECTRIC SHOCK, EXPLOSION, OR ARC FLASH
• Apply appropriate personal protective equipment (PPE) and follow safe
electrical work practices. See NFPA 70E, NOM-029-STPS or CSA Z462.
• This equipment must only be installed and serviced by qualied electri-
cal personnel.
• Turn o󰀨 all power supplying this equipment before working on or inside
equipment.
• Always use a properly rated voltage sensing device to conrm power is o󰀨.
• Replace all devices, doors and covers before turning on power to this
equipment. All wiring must comply with the National Electrical Code
(NEC) and applicable local codes.
• This equipment must be e󰀨ectively grounded per all applicable codes.
Use an equipment-grounding conductor to connect this equipment to the
power system ground.
• For proper operation, neutral and ground must be reliably connected.
Improper grounding will reduce or impede operation, and may result in
damage to the SPD.
• Conrm that the Surge Protective Device voltage rating on the module
or nameplate label is not less than the operating voltage.
• Do not supply more than 250VAC or 5 Amps to contacts
Failure to follow these instructions will result in death or serious injury.
Read all instructions before starting the installation of this product. These
instructions do not replace national or local electrical code.
The unit is designed for operation indoors in ambient temperatures of
-40ºC (-40ºF) to 60ºC (-140ºF) with a relative humidity of 0% to 95% (non-
condensing). The unit is provided in an industrial enclosure. Do not install
in areas with excessive dust, corrosive vapors, ammable materials or
explosive atmospheres.
Mount unit as close as possible to the service panel in close proximity to the
breaker that will power the SPD. To maximize performance, keep wire length
to the surge protective device (SPD) as short as possible.
#10 AWG wiring is provided with unit. To reduce the wiring impedance to
surge currents, the phase, neutral (if required), and ground conductors
are recommended to be twisted together and routed in the same raceway
(conduit). Avoid any sharp bends in the conductors
Feed all wires into the panel through the knockout selected and secure the
conduit connection.

ASCO 330 Surge Protective Device (SPD)
Installation Manual
Before making connections to the unit, verify the unit model number and
nameplate voltage rating are appropriate for connection to the power source
(See table).
1. It is recommended that a circuit breaker be used for installation and
connection to the service panel. See pages 5-6 for recommended
amperage.
2. Connect the white wire (if provided) of the SPD to the neutral of the
supply, and connect the green wire (if provided) of the SPD to source
ground.
3. Connect each Black Phase Wire to corresponding phase on the service
panel.
4. If the relay contact wires for remote sensing are not used, secure and
insulate the wires so they do not interfere with operation.
If using remote sensing, these wires are connected to COM (orange),
NC (blue), and NO (yellow) respectively.
Relay’s maximum switching capacity is 250VAC, 5A.
Apply power to the SPD and check status indications are normal. The
NEMA 1 unit status lights will be “green” and the red “service” indicator will
be o󰀨 for normal operation. If normal status indicators do not exist, see
“TROUBLESHOOTING”.
If any of the diagnostic indicators indicates a problem (i.e. red LED ON, and/
or green LED OUT), check all connections and voltages to the unit. If all
connections are acceptable, and proper voltages are supplied to the unit,
call ASCO Power Technologies at 800-237-4567.

HAZARD OF ELECTRIC SHOCK, EXPLOSION, OR ARC FLASH
• This device has been investigated by Underwriters Laboratories to
withstand, without exposing live circuits or components on power
sources, a voltage of two times (2x) the device ratings, and fault
currents of up to 65,000 AIC, as described in the Standard for Safety,
Surge Protective Devices (SPDs), Standard 1449, Fourth Edition.
Failure to follow these instructions will result in death or serious injury.
