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). |
| – DC + (Fig. 1h, pg. 5) | eFlow3NBV: 12VDC or 24VDC @ 2A continuous output (power-limited output). eFlow4NBV: 12VDC or 24VDC @ 4A continuous output (power-limited output). eFlow6NBV: 12VDC or 24VDC @ 6A continuous output (non power-limited output). eFlow102NBV: 12VDC @ 10A continuous output (non power-limited output). eFlow104NBV: 24VDC @ 10A continuous output (non power-limited output). |
| Trigger EOL Supervised | Fire Alarm Interface trigger input from a short or FACP. Trigger inputs can be normally open and normally closed from an FACP output circuit (power-limited input) (Fig. 1d, pg. 5). |
| NO, GND RESET | FACP interface latching or non-latching (power-limited output) (Fig. 1c, pg. 5). |
| + AUX – | Auxiliary Power-Limited output rated @ 1A (unswitched) (power-limited output) (Fig. 1f, pg. 5). |
| AC Fail NC, C, NO | Indicates loss of AC power, e.g. connect to audible device or alarm panel. The relay is normally energized when AC power is present. Contact rating 1A @ 30VDC (power-limited) (Fig. 1b, 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. Battery reconnection is reported within 1 minute (power-limited) (Fig. 1b, pg. 5). |
| – BAT + | Stand-by battery connections. Maximum charge current 1.54A (non-power-limited) (Fig. 1g, pg. 5). |
