NOTICE
LOSS OF BRANCH CIRCUIT POWER / LOSS OF SURGE
SUPPRESSION
• Perform periodic inspection of the surge protective device status
indicator lights as part of the preventative maintenance schedule.
• Promptly replace the surge protective device when an alarm state
exists.
• Use dry contacts to signal an alarm state to the central supervisory
system for unmanned, inaccessible, or critical installations.
• Use multiple surge protective devices to achieve redundancy for critical
applications.
Failure to follow these instructions can result in equipment damage.
At end-of-life conditions, Surge Protective Devices (SPDs) can lose their
ability to suppress power system transient voltage spikes and attempt to
draw excessive current from the line. This SPD is equipped with overcurrent
and overtemperature components that will automatically disconnect the
surge suppression elements from the mains should the surge suppression
elements reach end of life. Tripping of the branch circuit breaker or fuse
feeding the SPD can occur. Mitigate the tripping of the branch circuit breaker
or fuse feeding the SPD by coordinating the surge suppression elements
with the branch circuits.

Inspect the entire shipping container for damage or signs of mishandling be-
fore unpacking the device. Remove the packing material and further inspect
the device for any obvious shipping damage. If any damage is found and is
a result of shipping or handling, immediately le a claim with the shipping
company.
The device should be stored in a clean, dry environment. Storage tempera-
ture is -40 °F to +185 °F (-40°C to +85°C). All of the packaging materials
should be left intact until the device is ready for installation.
The identication nameplate is located on the side of the unit.
The device is designed to operate in an ambient temperature range of
-40 °F to +185 °F (-40°C to +85°C) with a relative humidity of 0 to 95%
non-condensing. This device has a Type 4X housing.
The device background noise is negligible and does not restrict the location
of the installation.
The device has been designed to be surface mounted. An additional ush
mount kit is also available if required (KITFMXF).
The service clearance should meet all applicable code requirements.
To obtain optimum surge suppression, locate the SPD as close as possible
to the circuitry being surge-limited to minimize the wire length. Minimizing
the wire length reduces the impedance between the circuitry and the SPD.
Refer to the Voltage Protection Rating (VPR) values on the SPD nameplate.
These VPR values were obtained by testing the SPD with six-inch long
leads (per UL1449). For every additional foot of wire beyond six inches, the
e󰀨ective VPR increases by approximately 160 volts.

Electrical
HAZARD OF ELECTRIC SHOCK, EXPLOSION, OR ARC FLASH
Conrm the surge protective device voltage rating on the module or
nameplate label is not less than the operating voltage.
Failure to follow these instructions will result in death or serious injury.
Prior to mounting the SPD, verify that the device has the same voltage
rating as the power distribution system in which it is installed. Compare the
nameplate voltage or model number on the SPD with the nameplate of the
electrical distribution equipment.
The specier or user of the device should be familiar with the conguration
and arrangement of the power distribution system in which the SPD is to be
installed. The system conguration of any power distribution system is based
strictly on how the secondary windings of the transformer supplying the ser-
vice 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. See Table 1 for the
service voltage of each SPD.

Protection and Disconnect Means
Location of Surge Protective
Device (SPD)
HAZARD OF ELECTRIC SHOCK, EXPLOSION, OR ARC FLASH
• Use conductors rated for the Overcurrent Protection Device (OCPD) per
applicable codes.
• Use conductors rated for the application per applicable codes.
Failure to follow these instructions will result in death or serious injury.
A branch circuit Overcurrent Protection Device (OCPD) either in the form of
a circuit breaker or fuse must be provided for the ASCO 360 Type 2 device.
The branch circuit OCPD should either provide or include a disconnecting
means.
Since the current drawn by the ASCO 360 device during normal operation is
negligible, the ASCO 360 device can be connected to a dedicated, separate
branch circuit or connected to a suitable existing branch circuit.
When connected to a separate, dedicated branch circuit, the OCPD setting
must be selected to protect the conductors feeding the ASCO 360 device
per applicable state and local building codes.
UL 1449 Type 1 SPDs have been designed and approved for line side appli-
cations prior to the main service disconnect without supplemental overcur-
rent protection. Type 2 SPDs must be installed on the load side of the main
Overcurrent Protective Device (OCPD). All installations should either provide
or include a disconnecting means.
Locate the SPD as close as possible to the circuit mains being surge-limited
to minimize the wire length and optimize SPD performance. Avoid long wire
runs so that the device will perform as intended. To reduce the impedance
that the wire displays to surge currents, the phase, neutral, and ground
conductors (wye and high-leg delta congurations), or phase and ground
conductors (delta congurations), must be routed within the same conduit
and tightly bundled or twisted together to optimize device performance.
Avoid sharp bends in the conductors. See Figures 2 and 3.

System Grounding
NOTICE
LOSS OF SURGE SUPPRESSION
• Verify that the service entrance equipment is bonded to ground in
accordance with all applicable codes.
Failure to follow these instructions can result in equipment damage.
The ASCO 360 has SPD elements connected from phase to ground. It is
critical that there be a robust and e󰀨ective connection to the building
grounding structure. The grounding connection must utilize an equipment
grounding conductor run with the phase and neutral connection of the power
system. Do not connect the SPD to a separate isolated ground.
For proper voltage suppression by the ASCO 360 SPD, use a single-point
ground system where the service entrance grounding electrode system is
connected to, and bonded to, all other available electrodes, building steel,
metal water pipes, driven rods, etc. (for reference, see NEC Art 250). The
ground impedance measurement of the electrical system must be as low as
possible and in compliance with all applicable codes for sensitive electronic
and computer systems.
System Grounding

• Do not use isolating bushings to interrupt a metallic raceway run.
• Do not use a separate isolated ground for the surge protective device.
• Verify proper equipment connections to the grounding system.
• Verify ground grid continuity by inspections and testing as part of a
comprehensive electrical maintenance program.
Failure to follow these instructions can result in equipment damage.
