INSTALLATION INSTRUCTIONS FOR THE LIEBERT

ACCUVAR® ACV SERIES SURGE PROTECTIVE DEVICE

WITH OPTIONAL FILTERING

The Liebert AccuVar® ACV Series Surge
Protective Device (SPD) is a high quality, high
energy surge current diversion system designed to
protect sensitive equipment from damaging
transient surges and electrical line noise. Proper
installation is required for maximum system
performance.

The installer should perform the following steps to
assure a quality installation. The entire installation
manual should be read before starting installation.
These instructions do not replace national or local
electrical codes. Check applicable electrical codes
to ensure compliance. Installation of the Liebert
AccuVar ACV Series Surge Protective Device
should only be performed by qualified personnel.

UNPACKING AND INSTALLATION

Suppression

Systems

Unpacking and Preliminary Inspection

1. Inspect the shipping crate(s) for damage or

signs of mishandling before unpacking the

unit.

2. If any damage as a result of shipping is

observed, immediately file a claim with the

shipping agency and forward a copy to your

local Liebert Sales Representative.

Storage

The unit should be stored in a clean, dry
environment. Storage temperature range is -55ºC
(-67ºF) to +85ºC (+185ºF). Care should be taken
to avoid condensation. All packing and shipping
materials should be left intact until the unit is
ready for final installation. If the unit has been
stored for an extended period of time, the unit
should be cleaned and carefully inspected before
placing into service.

Location Considerations

Environment – The unit is designed for operation
indoors in ambient temperatures of -40ºC (-40ºF)
to +50ºC (+122ºF) with a relative humidity of 0%
to 95% (non-condensing).

The cover screws and “O” rings are supplied inside
of the unit in the small plastic bag that also
contains the wiring ring terminals. To properly
attach the cover to the enclosure the four “O” rings
must be used with the four screws provided, prior
to placing the screw in hole of cover. Screws
should be torqued between 4 and 10 inch-pounds.

Note: To maintain the integrity of the “O”
rings, protection against direct sunlight is
advised.

Equipment Performance – For maximum system

performance, the unit must be located as close to
the protected circuit as practical to minimize
interconnecting wiring length.

For optimum transient surge protection,
coordinated surge suppression should be applied at
the service entrance, at all other electrical
connections to the building (telephone, CATV,
etc.), and at known transient surge generating
loads within the building (large motors, arc
welders, switched capacitors, etc.). Electrical line
noise protection should also be applied close to the
point of usage for sensitive electronic loads
(computers, electronic appliances, solid state
motor drives, etc.). For interconnected electronic
loads (such as by way of data cabling),
communication line protectors may also be applied
to the interconnect wiring.

The unit is provided in a NEMA 12, 4, and 4X
rated industrial use enclosure, which is dust, drip,
and water tight and should not be installed in areas
with flammable materials or explosive
atmospheres.

Outdoor Use – To assure water tightness for
outdoor use, “O” rings must be used with screws
to secure cover!
