Installation Instructions:
Wiring methods shall be in accordance with the National Electrical Code/NFPA
70/NFPA 72/ANSI, the Canadian
Electrical Code and with all local codes and authorities having jurisdiction.
The product is intended for indoor use only.
- 
Mount the eFlowNBV power supply/charger in desired location/enclosure (mounting hardware included). 
 Use metal standoffs for the bottom mounting holes to provide sufficient grounding for the board.
- 
Set desired DC output voltage by setting SW1 to the appropriate position on the power supply board (Fig. 1i, pg. 5). 
- 
Connect unswitched AC power (220VAC, 50/60Hz) to terminals marked [L, G, N] (Fig. 1a, pg. 5). 
 Use 14 AWG or larger for all power connections. Secure green wire leads to earth ground.
 Keep power-limited wiring separate from non-power-limited wiring (220VAC, 50/60Hz Input,
 DC Output (refer to Specifications chart pg. 3), Battery Wires).
 Minimum 0.25” spacing must be provided.
 CAUTION: Do not touch exposed metal parts.
 Shut branch circuit power before installing or servicing equipment.
 There are no user-serviceable parts inside.
 Refer installation and servicing to qualified service personnel.
- 
Measure output voltage before connecting devices. This helps avoid potential damage. 
- 
Connect devices to be powered to terminals marked [– DC +] (Fig. 1h, pg. 5). 
 For auxiliary device connection, this output will not be affected by Low Power Disconnect or Fire Alarm Interface. Connect the device to terminals marked [+ AUX –] (Fig. 1f, pg. 5).
- 
For Access Control applications batteries are optional. When batteries are not used, a loss of AC will result in the loss of output voltage. When the use of stand-by batteries is desired, they must be lead acid or gel type. 
 Connect the battery to terminals marked [– BAT +] (Fig. 1g, pg. 5) . Use two (2) 12VDC batteries connected in series for 24VDC operation (battery leads included). Use batteries – Castle CL1270 (12V/7AH), CL12120 (12V/12AH), CL12400 (12V/40AH), CL12650 (12V/65AH) batteries or UL-recognized BAZR2 batteries of an appropriate rating.
 Note: Separate enclosures must be used for housing 40AH or 65AH batteries.
- 
Connect appropriate signaling notification devices to AC FAIL & BAT FAIL (Fig. 1b, pg. 5) supervisory relay outputs. 
- 
To delay AC reporting for 2 hrs ., set SW2 to the appropriate DIP switch position [AC Delay] (Fig. 1c, pg. 5). 
- 
To enable or disable Low Output Power Shutdown set SW2 to the appropriate DIP switch position [Shutdown](Fig. 1c, pg. 5) . 
 10 . A short or NO or NC input triggers FACP [Trigger EOL Shutdown] (Fig. 1d, pg. 5).
 11 . Place a jumper for non-latching FACP. A momentary short on these terminals resets FACP latching
 [Trigger EOL Shutdown] (Fig. 1e, pg. 5). 
Wiring:
Use 18 AWG or larger for all low voltage power connections.
Note: Take care to keep power-limited circuits separate from non-power-
limited wiring (220VAC, Battery)
Maintenance:
The unit should be tested at least once a year for the proper operation as
follows:
Output Voltage Test: Under normal load conditions, the DC output voltage
should be checked for proper voltage level.
Battery Test:
Under normal load, conditions check that the battery is fully charged, and
check the specified voltage (12VDC @ 13 .2 or 24VDC @ 26 .4) both at the
battery terminal and at the board terminals marked [– BAT +] to ensure that
there is no break in the battery connection wires.
Replacing Batteries: Disconnect existing batteries. Connect the battery
to the terminals marked [– BAT +]. Use two (2) 12VDC batteries connected in
series for 24VDC operation.
LED Diagnostics:
| Red (DC) | Clear (AC1) / Green (AC) | Power Supply Status | 
|---|---|---|
| ON | ON | Normal operating condition. | 
| ON | OFF | Loss of AC. The standby battery is supplying power. | 
| OFF | ON | No DC output. | 
| OFF | OFF | Loss of AC. Discharged or no stand-by battery. No DC output. | 
Terminal Identification:
| Terminal Legend | Function/Description | 
|---|---|
| L, G, N | Connect 220VAC, 50/60Hz to these terminals: L to hot, N to neutral, G | 
to the ground (Fig. 1a, pg. 5).

Bat Fail NC, C, NO| Indicates low battery condition, e.g. connect to the alarm
panel.
The relay is normally energized when DC power is present. Contact rating 1A @
30VDC. A removed battery is reported within 5 minutes.
