READ AND FOLLOW ALL SAFETY
INSTRUCTIONS
IMPORTANT SAFEGUARDS
When using electrical equipment, you should always follow basic safety precautions,
including the following:
1. Read and follow all safety instructions.
2. Do not install the LSN (Life Safety Network) inverter system outdoors.
3. Do not install near gas or electric heaters or in other high-temperature locations.
4. Use caution when servicing batteries. Battery acid can cause burns to skin and
eyes. If acid is spilled on skin or in the eyes, ush with fresh water and contact a
physician immediately.
5. Equipment should be mounted in locations where it will not be readily subjected to
tampering by unauthorized personnel.
6. The use of accessory equipment not recommended by the manufacturer may
cause an unsafe condition and may void the warranty.
7. Do not use this equipment for other than intended use.
8. All servicing of this equipment must be performed by qualied service personnel.

102. Receiving, Moving and Storing Systems and Batteries
102.1 Shipping Damage
LSN inverter systems and batteries are normally shipped separately.
Carefully inspect all cartons upon receipt for evidence of shipping damage.
Notify carrier immediately of leaking or damaged cartons for possible concealed damage.
All LSN electronics cabinet cartons are shipped with tip and vibration indicators.
Refuse all shipments in which the tip or vibration indicators have been activated.
102.2 Moving Units and Batteries
CAUTION: Batteries and LSN Electronics cabinets are very heavy. Proper equipment should
always be used to move batteries and units to avoid damage and personal injury.
WARNINGS:
• ALWAYS WEAR PERSONAL EYE PROTECTION WHEN WORKING WITH BATTERIES - SEE PAGE 10
• Batteries contain liquid caustic or acid electrolytes which CAN CAUSE SEVERE BURNS.
Care must be taken when moving batteries to avoid tipping and spillage of electrolyte material.
In case of accidental spill.
ANTIDOTE:
• EYES: Flush immediately with owing water for at least 15 minutes. Seek medical attention.
• EXTERNAL: Flush immediately with water. Seek medical attention.
102.3 Temporary Storage of Units and Batteries
For temporary storage of LSN inverter systems and batteries prior to installation, select a clean, cool, dry location with
normalventilationforhumanhabitationandleveloors.
CAUTION: Batteries and LSN Electronics cabinets are very heavy. Check to assure that the oor in the
temporary storage area is capable of safely bearing the load.
IMPORTANT:
Lengthy storage of batteries will cause irreversible damage to the cells.
Failure to connect LSN inverter system batteries to an energized charging circuit within 90 days from the date
of shipment will void the battery warranty.
Storage Temperature:
Storeallbatteriesat0°to+40°C(32°to+104°F).Batterieswillhavealongershelflifeifstoredat25°C(77°F).
TheLSNelectronicsandbatterycabinetsmaybestoredat-20°to+60°C(-4°to+140°F).
Ventilation:
The air around the unit must be clean, dust-free, and free of corrosive chemicals or other contaminants. Do not place
the LSN inverter system or batteries in a sealed room or container.
DANGER: EXPLOSIVE - CAN CAUSE BLINDNESS OR OTHER SEVERE INJURIES.
Every type of battery can produce hydrogen gas, even sealed, maintenance-free batteries. The gas is vented through
the vent caps and into the air.
Do not allow smoking, sparks, or ames in battery storage location because hydrogen is concentrated under
the vent cap of each cell of the battery. Hydrogen is highly explosive, and is hard to detect because it is
colorless, odorless, and lighter than air.

103. Installation Requirements
103.1 Operating Environment
InstalltheLSNinvertersysteminaclean,cool,dryplacewithnormalventilationforhumanhabitationandleveloors.
CAUTION: Batteries and LSN Electronics cabinets are very heavy. Check to assure that the
oor is capable of safely bearing the load.
Operating Temperature:
LSN inverter Systems are UL Listed for 20° to 30° C (+ 68° to +86° F) operation.
TheLSNInverterSystemhasadesignedoperatingrangeof0°to+40°C(+32°to+104°F)atupto95%relative
humidity. Installation in environments at the temperature extremes of the designed operating range may effect unit
performance or reduce service life.
Battery performance and service life is maximized if the operating temperature is maintained at 25° C (77° F) .
Ventilation:
The air around the unit must be clean, dust-free, and free of corrosive chemicals or other contaminants. Do not place
the LSN inverter system or batteries in a sealed room or container.
Batteries:
Thetemperatureshouldbenear25°C(77°F)foroptimumbatteryperformance.
Temperature Effect On Performance:
Batterieswillbelessefcientattemperaturesbelow18°C(65°F),andhightemperatureswillreducebatterylife.
Typically,at35°C(95°F),batterylifewillbehalfofwhatitwouldbeatnormaltemperatureof25°C(77°F).At45°C
(113°F),batterylifewillbeone-fourthofnormal.
WARNING: Every type of battery can produce hydrogen gas, even sealed, maintenance-free batteries. The gas is
vented through the vent caps and into the air, mainly when the unit is charging the batteries. The batteries produce the
most hydrogen when maximum voltage is present in fully charged batteries. The amount of current that the charger
suppliestothebatteries(notthebatteryampere-hour)determineshowmuchhydrogenisproduced.
Do not allow smoking, sparks, or ames in battery storage location because hydrogen is concentrated under
the vent cap of each cell of the battery. Hydrogen is highly explosive, and is hard to detect because it is
colorless, odorless, and lighter than air.
IMPORTANT:
Lengthy storage of batteries will cause irreversible damage to the cells.
Failure to connect LSN inverter system batteries to an energized charging circuit within 90
days from the date of shipment will void the battery warranty.
103.2 High Altitude Operation:
Themaximumoperatingtemperaturedrops1°Celsiusper300meters(2°Fper1000feet)abovesealevel.Maximum
elevationis3000meters(10,000feet).
CAUTION
NEVER INSTALL BATTERIES IN A

105. Battery Installation and Connection
Installing the Batteries and DC Wiring
Important Safety Precautions
Theinstallermusttaketheseprecautions:
1. Wear protective clothing, eye-wear, rubber gloves and boots. Batteries contain corrosive acids or
caustic alkalis and toxic materials and can rupture or leak if mistreated. Remove rings and metal
wristwatches or other metal objects and jewelry. Don’t carry metal objects in pockets where the
objects can fall onto the batteries or into the LSN inverter system or battery cabinet.
2. Tools must have insulated handles so that they will not short battery terminals. Do not allow a tool to
short a battery terminal to another battery terminal or to the cabinet at any time. Do not lay tools or
metal parts on top of the batteries, and do not lay any objects where they could fall onto the batteries
or into the cabinet.
3. Install the batteries as shown on the battery wiring diagram provided in this manual or with the
battery cable kit. When connecting cables, never allow a cable to short across a battery’s terminals,
the string of batteries, or to the cabinet.
4. Align the cables on the battery terminals so that the cable lug will not contact any part of the cabinet
even if the battery is moved. Keep the cable away from any sharp metal edges.
5. Install the battery cables so they cannot be pinched by the battery cabinet or the LSN inverter system
doors.
6. External battery cabinet chassis ground (or earth) must be connected to the LSN inverter system
unit’s chassis ground (or earth). The ground conductor must be insulated. If you use conduit, this
ground conductor must be routed in the same conduit as the battery conductors.
7. Where conductors may be exposed to physical damage, protect conductors in accordance with NEC
requirements.

shock. Batteries may cause severe injury if the terminals are shorted together or to ground (earth).
Be extremely careful to avoid electric shock and burns caused by contacting battery terminals or
shorting terminals during battery installation. Do not touch uninsulated battery terminals.
