102. Receiving, Moving and Storing Systems and Batteries
102.1 Shipping Damage
Inverter system batteries are 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.
102.2 Temporary Storage of Units and Batteries
For temporary storage of Si- inverter systems and batteries prior to installation, select a clean, cool,
dry location with normal ventilation for human habitation and level floors.
Storage Temperature:
Store all batteries at 0° to +40° C (32° to +104° F). Batteries will have a longer shelf life if stored at 15°
C (60° F). The Si- electronics and battery cabinets may be stored at -20° to +60° C (-4° to +140° F).
IMPORTANT:
Lengthy storage of batteries will cause irreversible damage to the cells.
Failure to connect Si- inverter system batteries to an energized charging circuit within 90 days from
the date of shipment will void the battery warranty.
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 flames 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 Si- inverter system in a clean, cool, dry place with normal ventilation for human habitation
and in such a location to hamper vandalism but allow easy access for testing and maintenance.
Operating Temperature:
Si- inverter Systems are UL Listed for 20° to 30° C (+ 68° to +86° F) operation.
Battery performance and service life is maximized if the operating temperature is maintained at 25° C
(77° F).
Temperature Effect On Lead Calcium Battery Performance:
Lead Calcium batteries will be less efficient at temperatures below 20° C (68° F), and high tempera-
tures 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.
Ventilation:
The air around the unit must be clean, dust-free, and free of corrosive chemicals or other contami-
nants. Do not place the Si- inverter system or batteries in a sealed room or container.
CAUTION: Never Install Batteries in A Sealed Room Or Enclosure
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).
104. Cabinet Mounting
104.1 Tools Required
The following tools are required to install the system:

200.4 Routine Battery Inspection and Maintenance
Sealed Lead-Calcium Batteries
Maintenance-free cells are the most common type of battery used today in standby equipment. By
design it is as maintenance free as a battery can be. It is recommended, however, that some simple
steps be taken to increase system life and maximize reliability:
A) A quarterly visual check of the battery should be conducted to look for deformities in the
battery case, electrolyte leakage and/or terminal corrosion. Any batteries with these
conditions are defective and should be replaced. Any corroded terminals found,
regardless how slight, are to be cleaned at once to prevent system failure.
B) Once a year, all battery connections should be checked for tightness and cleaned and
retightened as necessary.
200.5 Battery Replacement Procedure
WARNING:
Always use the same quantity and type of battery as replacements.
Substituting batteries not supplied by the Manufacturer will void the UL listing of the system and may
cause equipment failure. To ensure the superior performance of your Si- inverter system and to
maintain proper charger operation, replace spent batteries only with those having the same part
number, voltage and ampere-hour rating as the original batteries.
1. Follow the proper shut down procedure as described in Section 200.1.
2. Carefully disconnect all battery wiring. Remove battery retention bracket(s).
3. Remove the batteries from the cabinet.
4. Install new batteries following the instructions outlined in Section 106.2.
200.6 Battery Disposal
WARNINGS:
• Do not dispose of batteries in a fire, the batteries could explode.
• Do not open or mutilate batteries.
• Released electrolyte is highly toxic and harmful to the skin and eyes.
CAUTION: Batteries contain lead or cadmium, depending on model. Many state and local
governments have regulations about used battery disposal. Please dispose of the batteries
properly.
15.
200.2 Routine System Maintenance
The Si- inverter system unit is designed to provide years of trouble-free operation. The unit does
require some routine attention to ensure peak performance. The Manufacturer recommends a
Preventative Maintenance check be performed by a qualified service technician at least every six
months. The technician must observe important safety precautions while performing the following
recommended tasks:
• Inspect and clean the unit interiors
• Inspect all batteries for leaks, case swelling or terminal corrosion
• Perform an emergency operation test to check operation of all critical connected loads
200.3 Manual Routine Inverter Tests
NFPA101 requires that Emergency Lighting Equipment be tested on a monthly basis for a period of at
least 5 seconds, and a minimum of 90 minutes once a year. We strongly recommend these guidelines
be followed to insure system readiness, and to prolong battery life. The SI- system was designed with
a front panel test switch to facilitate monthly testing. Simply depress the button and hold to test
the inverter at anytime. Once released, the Si- will revert back to standby operation. For annual 90-
minute discharge or other prolonged tests, simply turn off the AC Input breaker at the service panel.
