Eaton Crouse-Hinds Light-Pak N2LPSM2 Informations D'installation Et D'entretien

Light-Pak™ N2LPSM2 LED emergency lighting system
(N2LPSM2 K57 – replacement charger board and battery kit)
Installation & maintenance information
REPLACEMENT CIRCUIT BOARD & BATTERY KIT
N2LPSM2 K57 kit consists of:
(1) Circuit board and battery assembly with mounting plate
(1) Sealed Ni-Cad battery
(1) CID101 corrosion inhibitor device
Details indicating LED logic is given below:

* Steady light (no blinks)
* - * Light blinks once
**-** Light blinks twice
***-*** Light blinks three times
****-**** Light blinks four times
Table 1. Detail Indication Logic
Immediately after supply power is initiated, the indicating lamp will blink/pulse to
indicate that the unit is charging. Once installed with supply power, the N2LPSM2
requires 15 hours to charge the battery. Once the unit has completed charging, the
indicating light will stop blinking and go to steady. Every 12 months, the unit will
automatically perform a 90 minute battery discharge test. Every 30 days, the unit
will also automatically perform a 30 second self-test. If the battery, board or lamp
has been compromised, the indicator light will blink accordingly.
At the completion of the test, if it is determined not to have met the 90 minute
requirement, the indicating lamp will display circuit failure (3 blinks). At any time,
if the battery connection is not adequate, the indicating lamp will display a battery
failure (2 blinks).
!
To prevent injury from electric shock, all power must be removed from the
fixture during maintenance.
!
Even after disconnect, batteries will still be live. To prevent electrical shock
and explosion, take extra care not to touch leads together or to ground.

REMOVAL OF EXISTING CIRCUIT ASSEMBLY
Explosion hazard: this luminaire is provided with a factory installed
emergency lighting battery pack. Do not conduct ANY maintenance (including
CONNECTING/DISCONNECTING the battery pack) until the area is deemed to
be clear of hazardous atmospheres and all incoming power is turned OFF .
1. Disconnect branch AC power at circuit breaker and lock out.
2. Ensure power is OFF and ensure the area is clear of hazardous atmospheres
before performing maintenance.
3. Loosen (do not remove) the six (6) captive cover screws of the N2LPSM2
power supply housing and carefully place the cover aside for reassembly later.
4. Remove four (4) 1/4-20 screws and lock washers that secure the mounting
plate to the enclosure, and disconnect wire leads at the pilot light, battery
pack, pushbutton and lamp heads. If the unit utilizes the external battery
disconnect switch option, disconnect the battery disconnect switch leads
from the battery output at the WAGO connectors.
5. Disconnect all incoming connections from terminals.
6. Remove old interior assembly and set aside.
7 . Install the new interior assembly inside the existing enclosure using the same
four (4) 1/4-20 screws and lock washers removed in Step 4. Torque screws to
21-25 in.-lbs.
8. Make all wiring connections following the
wiring diagram located in the new assembly
(see Figure 1).
9. Connect the pilot light, battery pack, pushbutton
and lamp heads. If the unit utilizes the external
battery disconnect switch option, reconnect the
leads of the battery disconnect switch at the
WAGO connectors.
10. Connect line voltage to the line input of the
terminal block. Connect neutral to neutral input of terminal block. Connect all
equipment grounding conductors to terminal GRD.
11. Verify that the battery connector is connected to the accompanying circuit
board connector. If not, execute the connections.
12. Test wiring for correctness with continuity checks and also for unwanted
grounds with insulation resistance tester.
COMPLETE INSTALLATION
1. Install CID101 corrosion inhibitor device (supplied in plastic envelope with
instruction sheet). Recommended location is on the inside surface of the top
of the enclosure near the right side fixture stem.

2. Close cover and torque all six (6) cover screws to 25 in.-lbs.
3. Test emergency lighting system for proper operation (see Table 1 for detail

Solution
Verify power to fixture
Verify battery is properly connected to circuit
board
Verify battery voltage under no load is 13V or
higher after 15 hour charge. If less than 13V,
consult factory for battery replacement. If replacing
the battery does not satisfy the blink code error, consult
factory for circuit board replacement.
