Eflowv Power Supply/Charger; Installation Instructions - Altronix eFlowNAD8V Series Installation Manual

eFlowV Power Supply/Charger:

• Input: 220VAC (working range 198VAC - 256VAC), 50/60Hz.
• For output voltage and supply current refer to eFlowNA8DV Series Configuration Chart, pg. 3.
• Auxiliary power-limited output rated @ 1A (unswitched).
• Overvoltage protection.
• Built-in charger for sealed lead acid or gel type batteries.
• Maximum charge current 1.54A.
• Automatic switch over to stand-by battery when AC fails.
Transfer to stand-by battery power is instantaneous with no interruption.
• Supervised Fire Alarm disconnect (latching or non-latching) 10K EOL resistor.
Operates on a normally open (NO) or normally closed (NC) trigger.
• AC fail supervision (form "C" contacts).
• Battery fail and presence supervision (form "C" contacts).
• Low power shutdown. Shuts down DC output terminals if battery voltage drops below 71-73% for 12V units
and 70-75% for 24V units (depending on the power supply). Prevents deep battery discharge.
• For fuse rating, refer to eFlowNA8DV series Configuration Chart, pg. 3.
• Green AC Power LED indicates 120VAC present.
• AC input and DC output LED indicators.
• Short circuit and overload protection.
• Enclosure accommodates up to two (2) 12AH batteries.
Enclosure dimensions: 15.5" x 12" x 4.5" (393.7mm x 304.8mm x 114.3mm).
Wiring methods shall be in accordance with the National Electrical Code/NFPA 70/ANSI, The Canadian Electrical
Code, Part I, Part II and with all local codes and authorities having jurisdiction. The product must be located indoors
within the protected premises.

1. Mount unit in desired location. Mark and predrill holes in the wall to line up with the top two keyholes in
the enclosure. Install two upper fasteners and screws in the wall with the screw heads protruding. Place
the enclosure's upper keyholes over the two upper screws, level and secure. Mark the position of the lower
two holes. Remove the enclosure. Drill the lower holes and install the two fasteners. Place the enclosure's
upper keyholes over the two upper screws. Install the two lower screws and make sure to tighten all screws.
Enclosure Dimensions, pg. 16.
2. Connect AC circuit (220VAC, 50/60Hz) as follows: Green branch wire connects to earth (safety) ground
Line and Neutral to the connector on power supply board marked [L, N] respectively (Fig. 3, pg. 9).
Do not use terminal marked [G]. Use 14 AWG or larger for all power connections.
Secure green wire lead attached to the chassis to earth ground.
Keep power-limited wiring separate from non power-limited wiring.
Minimum 0.25" spacing must be provided (Fig. 3, pg. 9).
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.
3. Select desired DC output voltage by setting SW1 to the appropriate position on the power supply board
(eFlow4NA8DV and eFlow6NA8DV) (Fig. 1, pg. 8).eFlow102NA8DV power supply is factory set at 12VDC.
eFlow104NA8DV power supply is factory set at 24VDC.
4. Measure the output voltage of the unit before connecting any devices to ensure proper operation.
Improper or high voltage will damage these devices.
5. Output options (Fig. 2, pg. 8):
The unit will provide either eight (8) switched power outputs, eight (8) dry form "C" outputs, or any
combination of both switched power and form "C" outputs.
