Do not use benzine, thinner or alcohol for cleaning. When removing dust and dirt, put diluted, mild
detergent on a cloth and then wring out the cloth. Remove the dust and dirt with the cloth and then
wipe the cleaned area with a dry cloth.
Thinner
Do not place any equipment in the following environments:
• Locations that are exposed to direct sunlight
• Locations where the moisture level exceeds the allowed level
• Locations where the equipment might be exposed to water, oil, or chemicals
• Locations with very low temperatures, such as in a walk-in cooler or freezer
• Locations that are exposed to Electromagnetic Interference (EMI) from devices such as television
sets and two-way radios
• Locations that receive illegal electric waves
The life expectancies of the system and the main power source will be shortened if placed in a loca-
tion that is affected by hydrogen sulfide or salt, such as a seaside area.
Installation Environment
Consider the following items before the installation.
Stability
WARNING Install the system with anchor bolts to prevent constant movement or vibration, such as from a nearby
motor or automatic door, and to resist catastrophic movement from natural disasters, such as an
earthquake. If the system moves or falls, an injury could occur.
Floor, Wall and Ceiling
WARNING The wall and ceiling materials must be resistant to Electrostatic Discharge (ESD) and provide heat
insulation. Since the battery's life expectancy depends on the ambient temperature, the room where
the battery is installed must be well ventilated and vented to the outside. Check the battery specifica-
tions to determine if the battery can or cannot be installed near a motor or a power transformer.
The floor material that is under and around the system must be resistant to ESD.
Windows
CAUTION Keep all of the windows closed if the location is affected by dust, sea breeze or corrosive gas. Cur-
tains or blinds are necessary to avoid direct sunlight.
Fire Extinguisher
WARNING Place a fire extinguisher for electrical fires (such as a carbon-gas fire extinguisher or a halon-gas fire
extinguisher) near the system. It is recommended that the room also be equipped with an automatic
fire-detection system. In the event of smoke and fire, turn off the main power source and the backup
battery, then use the fire extinguisher to put out the fire while trying to avoid inhaling any smoke.
