Final Shut Down Procedure
1. Open the unit’s front access panel.
2. Turn off the DC Input breaker first and then the AC Input breaker. Also turn off all optional AC Output circuit breakers if supplied.
CAUTION: HAZARDOUS ENERGY IS STORED IN CAPACITORS INSIDE THE Inverter UNIT. AFTER TURNING
OFF SWITCHES, ALLOW 5 MINUTES FOR CAPACITORS TO DISCHARGE BEFORE ATTEMPTING ANY SERVICE PROCEDURES.
3. If the service technician does not need to access the inside of the unit, keep the unit's front cover/door closed.
4. If the unit will be shut off for an extended period of time, recharge batteries every 60 to 90 days.
CAUTION: The batteries will be damaged and the warranty voided if not routinely recharged.
NOTE:
To turn power back on, follow the “System Start-up Procedure” outlined in Section 108. Be sure to complete all of the steps to
as sure the unit will operate properly.
300.2 Routine System Maintenance
The Inverter unit is designed to provide years of trouble-free operation. The unit does require some routine attention to assure peak
performance. Philips Emergency Lighting 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
300.3 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 guide-lines be followed to insure system readiness, and to prolong battery life. The
Inverter 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 Inverter will revert back to standby operation; this may take a few seconds to allow the unit to
synchronize back to the line. For annual 90-minute discharge or other prolonged tests, simply turn off the AC Input breaker.
300.4 Battery Maintenance and Replacement
This section provides precautions for qualified service personnel working with unit batteries.
Important Safety Precautions
The service technician 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 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 Inverter system cover/doors.
6. Where conductors may be exposed to physical damage, protect conductors in accordance with NEC requirements.
7. If replacing batteries or repairing battery connections, follow the procedure in this manual to shutdown the Inverter
system and remove both AC and DC input power.
8. Full voltage and current are always present at the battery terminals. The batteries used in this system can produce dangerous voltages,
extremely high currents, and possible risk of electric 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 un-insulated battery terminals.
9. A qualified electrician who is familiar with battery systems and required precautions must install and service the batteries. Any battery
used with this unit shall comply with the applicable requirements for batteries in the standard for emergency lighting and power
equipment, UL 924. Cabinets are designed to be used with, and batteries must be replaced by identical cells or a Philips Emergency
Lighting approved equivalent. If using substitute batteries not supplied by Philips Emergency Lighting, the unit’s UL listing will be
void, and the equipment may fail to perform properly. The installation must conform to national and local codes as well. Keep
unauthorized personnel away from batteries.
CAUTION:
A battery can present a risk of electrical shock and high short circuit current. Battery replacement should only
be performed by qualified service personnel familiar with battery systems. All safety precautions outlined at the
beginning of this section must be observed when servicing, maintaining or replacing batteries.
