Installation, Operation and Maintenance Manual 2 Liebert TVSS Units SL-22085 Rev 2, 11/2006
Surge Suppression Systems
INSTALLATION INSTRUCTIONS
The Liebert Surge Protective Devices (SPDs) are high quality,
high energy surge current diversion systems designed to
protect sensitive equipment from damaging transient voltage
surges. 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
SPD system should only be performed by qualifi ed personnel.
UNPACKING AND INSTALLATION
Unpacking and Preliminary Inspection
1. Inspect the shipping crate(s) for damage or signs of
mishandling before unpacking the unit.
2. Remove any securing bands and cardboard packing and
inspect the unit for any obvious shipping damages.
3. If any damage as a result of shipping is observed, immediately
fi le a claim with the shipping agency and forward a copy to
your local Liebert Sales Representative.
Handling Considerations
Larger units are bolted to a shipping pallet to facilitate handling
by forklift or pallet jack. Check the size and weight. Refer to
the cabinet data furnished with the unit.
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 fi nal 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 +60ºC (+140ºF) with
a relative humidity of 0% to 95% (non-condensing).
The unit is provided in an industrial use enclosure, which is
dust-tight and drip-tight and should not be installed in areas
with excessive dust, corrosive vapors, fl ammable materials or
explosive atmospheres.
Audible Noise — The audible noise of the unit is less than
40 dB at 5 feet, which allows its placement within almost any
room if desired.
Service Clearances — Service clearance is needed for units with
hinged doors on the front that are capable of being opened.
Thirty-six inches (36 in/914 mm) minimum is recommended.
For optimum transient surge protection, coordinated surge
suppression should be applied at the service entrance and all
other electrical connections to the building (telephone, CATV,
etc.), at known surge generating loads within the building
(large motors, arc welders, switched capacitors, etc.), as well
as at sensitive electronic loads (such as computers, electronic
appliances, solid state motor drives, etc.). For interconnected
electronic loads (such as by way of data cabling), transient surge
suppression should also be applied to the interconnecting
wiring (data cables).
Mounting — Unit is intended to be wall mounted. Refer to
individual instruction sheet or unit submittal drawings for
typical mounting dimensions and weight.
Warnings Defi ned
Danger: Indicates an imminently
hazardous situation that, if not
avoided, will result in death or
serious injury. This signal word
is to be limited to the most
extreme situations.
Warning: Indicates a potentially
hazardous situation that, if not
avoided, could result in death or
serious injury.
Caution: Indicates a potentially
hazardous situation that, if not
avoided, may result in minor or
moderate injury. It may also be used
to alert against unsafe practices.
EQUIPMENT PERFORMANCE!!
To maximize system performance locate unit as
close as possible to protected circuit and keep inter-
connecting wiring less than 5 ft.
