Important Safety Instructions
Before using this equipment read all manuals and other documents related to this UPS and other equipment
connected to this UPS. SAVE THESE INSTRUCTIONS –This manual contains important safety and operating
instructions for the CUPS. If a replacement copy of a manual is needed, it can be found at www.lamarchemfg.com.
Electrical Safety
WARNING: Hazardous Voltages are present at the input of power systems. The output from UPS and
from batteries may be low in voltage, but can have a very high current capacity that may cause severe
or even fatal injury.
When working with any live battery or power system, follow these precautions:
•Never work alone on any live power system; someone should always be close enough to come to your aid.
•Remove personal metal items such as rings, bracelets, necklaces, and watches.
•Wear complete eye protection (with side shields) and clothing protection.
•Always wear gloves and use insulated hand tools.
WARNING: Lethal Voltages are present within the power system. Parts inside the UPS may still be
energized even when the UPS has been disconnected from the AC input power. Check with a meter
before proceeding. Do not touch any uninsulated parts.
•A licensed electrician should be used in the installation of any UPS.
•Always disconnect the UPS from the supply, batteries, and loads before performing maintenance, replacing
parts, or cleaning.
•Always assume that an electrical connection is live and check the connection relative to ground.
•Be sure that neither liquids nor any wet material comes in contact with any internal components.
•Do not operate this UPS outside the input and output ratings listed on the UPS nameplate.
•Do not use this UPS for any purpose not described in the operation manual.
Mechanical Safety
•This UPS or parts of the UPS may get very hot during normal operation, use care when working nearby.
•Do not expose equipment to rain or snow. Always install in a clean, dry location.
•Do not operate equipment if it has received a sharp blow, been dropped, or otherwise damaged in any way.
•Do not disassemble this UPS. Incorrect re-assembly may result in a risk of electric shock or fire.
Battery Safety
WARNING: Follow all of the battery manufacturer’s safety recommendations when working with or
around battery systems. DO NOT smoke or introduce a spark or open flame in the vicinity of a battery.
Some batteries generate explosive gases during normal battery operation.
•When charging Lithium-Ion batteries, a B.M.S. must be utilized.
•To reduce risk of arc, connect and disconnect the battery only when the UPS is off.
•If it is necessary to remove battery connections, always remove the grounded terminal from the battery first.
•Remove personal metal items such as rings, bracelets, necklaces, and watches.
•Always wear rubber gloves, safety glasses, and a rubber lined vest/apron when working near a battery.
•Have plenty of fresh water and soap nearby in case the battery electrolyte contacts skin, clothing, or eyes.
•If the battery electrolyte contacts skin or clothing, wash immediately with soap and water.
•If the electrolyte enters the eye, immediately flood the eye with running cold water for at least ten (10)
minutes and seek medical attention immediately.
•Do not drop or place any materials on a battery. A spark or short-circuit could cause an explosion.

iii
UPS Location
•Allow at least 6 inches of free air on all vented surfaces for proper cooling
•Allow sufficient clearance to open the front panel for servicing.
•Do not operate this UPS in a closed-in area or restrict ventilation in any way.
•Do not place UPS below battery.
•Never allow battery electrolyte to drip on this UPS when reading the specific gravity or filling the battery.
•Never place this UPS directly above a standard flooded battery. Gases from the battery will corrode and
damage equipment.
•A sealed maintenance free or valve regulated lead acid (VRLA) battery may be placed below this equipment.
Check for Damages.
Prior to unpacking the product, note any damage to the shipping container and take pictures. Unpack the product
and inspect the exterior and interior of product for damage. If any damage is observed, take pictures and contact
the carrier immediately to file a damage claim. Contact La Marche for a Return Material Authorization number to
have the UPS sent back for evaluation and repair.
CAUTION: Failure to properly file a claim for shipping damages, or provide a copy of the claim to La
Marche, may void warranty service for any physical damages reported for repair.
Returns for Service
Save the original shipping container. If the product needs to be returned for service, it should be packaged in its
original shipping container. If the original container is damaged/unavailable, make sure the product is packed
with at least three inches of shock-absorbing material to prevent shipping damage. La Marche is not responsible
for damage caused by improper packaging of returned products.
Handling
Equipment can be very heavy with uneven distribution of weight. Use adequate manpower or equipment for
handling. Until the equipment is securely mounted, care must be used to prevent equipment from being accidently
tipped over or dropped.

be on.
2. Switch on AC input breaker. After line power is qualified, the LCD will display normal, buck or boost
according to line voltage range and line threshold setting.
Note: AVR function default setting is disabled. You may activate it via LCD panel or USB/RS232/SNMP
communication.
Switch the UPS from line mode to battery mode
UPS will operate in battery mode if manually switch the input circuit breaker OFF. The LCD will display “Battery”
and output LED will flash to show the UPS is running on backup battery power.
Switch from battery mode to line mode
After switching on the input circuit breaker, if line input is qualified, UPS will transfer to line mode with output LED
on to show UPS is running from utility power.
Note: If UPS keeps switching between inverter and line mode because of a noisy line, the setting of “UPS Sense
type”should be changed from Normal to Generator.
Switch off procedure
For any reason you need to switch off UPS, please follow below procedure.
1. Switch off output circuit breaker.
2. Switch off input circuit breaker.
3. Switch off battery circuit breaker. The output LED will turn off and LCD display will shut off.
