Before working with any live battery or power system, follow these precautions:
a. Remove all metallic jewelry, such as watches, rings, metal rimmed glasses, or necklaces.
b. Wear safety glasses with side shields at all times during the installation.
c. Use OSHA approved insulated hand tools. Do not rest tools on top of batteries.
WARNING!
Lethal voltages are present within the power system. Always assume that an electrical
connection or conductor is energized. Check the circuit with a voltmeter with respect to the
grounded portion of the enclosure (both AC and DC) before performing any installation or
removal procedure.
WARNING!
Follow battery manufacturer’s safety recommendations when working around battery systems.
Do not smoke or introduce an open flame when batteries (especially vented batteries) are
charging. When charging, batteries vent hydrogen gas, which can explode.
WARNING!
Hazardous voltages and/or energy levels can be present at the input of power systems. The DC
output from rectifiers and batteries, though not dangerous in voltage, has a high short-circuit
current capacity that may cause severe burns and electrical arcing.
• Do not work alone under hazardous conditions.
• A licensed electrician is required to install permanently wired equipment. Input voltages can range up to
240 Vac. Ensure that the utility power is disconnected and locked out before performing any installation or
removal procedure.
• Ensure that no liquids or wet clothes come into contact with internal components.
• Hazardous electrically live parts inside this unit are energized from the batteries even when the AC input
power is disconnected.
• The enclosure which contains the DC or AC power system along with customer installed radios must remain
locked at all times, except when authorized service personnel are present.
• Always assume electrical connections or conductors are live. Turn off all circuit breakers and double-check
with a voltmeter before performing installation or maintenance.
• Place a warning label on the utility panel to warn emergency personnel that a reserve battery source is pres-
ent which will power the loads in a power outage condition or if the AC disconnect breaker is turned off.
• At high ambient temperature conditions, the internal temperature can be hot so use caution when touching
the equipment.
1.4 Battery Safety
• Never transport an enclosure with batteries installed. Batteries must ONLY be installed after the enclosure
has been securely set in place at its permanent installation location. Transporting the unit with batteries in-
stalled may cause a short circuit, fire, explosion, and/or damage to the battery pack, enclosure and installed
equipment.
• Servicing and connection of batteries must be performed by, or under the direct supervision of, personnel
knowledgeable of batteries and the required safety precautions.
• Batteries contain or emit chemicals known to cause cancer and birth defects or other reproductive harm.
Battery post terminals and related accessories contain lead and lead compounds. Wash your hands after
handling batteries.
• Batteries are hazardous to the environment and should be disposed at a recycling facility. Consult the battery
manufacturer for recommended local authorized recyclers.

8.1 Heat Exchanger Fan Test Procedure
There are six heat exchanger fans. Three inner loop fans are located on the inside of the door and three outer loop
fans on the outside of the door. Perform the following procedure to test the fans.
1. Pull out the plunger of the heat exchanger power door switch.
2. If the fans do not turn on, carefully apply heat to the heat exchanger thermostat using a heat gun. The fans
should turn on above 30°C (86°F). If the fans still do not turn on, check the status of the cooling system breaker
or fuse.
3. Operation of the inner loop fans can be verified through visual inspection.
4. Unplug one of the outer loop fan connectors and listen for a noticeable drop in the sound level of the outside
fans. Plug the fan connector back in.
5. Repeat Step 4 for the two other outer loop fans.
