Specifications:
Installation Instructions:
Wiring methods shall be in accordance with the National Electrical Code/NFPA 70/NFPA 72/ANSI,
The Canadian Electrical Code, Part 1 and with all local codes and authorities having jurisdiction.
Product is intended for indoor use only.
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, pgs. 11-12). Secure enclosure to earth ground.
2. Connect unswitched AC power (220VAC, 50/60Hz) to terminals marked [L, N] (Fig. 1a, pg. 5).
Use 14 AWG or larger for all power connections. Secure green wire lead to earth ground lug.
Keep power-limited wiring separate from non power-limited wiring (220VAC 50/60Hz Input,
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.
For Fire Alarm applications the outputs are “Special Applications” only, see list (refer to Appendix A, pg. 12).
3. Measure output voltage before connecting devices. This helps avoiding potential damage.
4. Connect devices to be powered:
a. For eFlow104NV/eFlow104NXV connect devices to terminals marked [– DC +] (Fig. 1h, pg. 5).
b. For other Power Distribution Models connect devices to be powered to terminal pairs 1 to 8 marked
[1P & 1N] through [8P & 8N] (Fig. 3a & 3b, pg. 6) or 1 to 16 marked [1P & 1N] through [16P & 16N]
(Fig. 4a & 4b, pg. 6) carefully observing correct polarity.
For auxiliary device connection: this output will not be affected by Low Power Disconnect or Fire Alarm
Interface. Connect device to terminals marked [+ AUX –] (Fig. 1f, pg. 5).
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 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 - Casil CL1270
(12V/7AH), CL12120 (12V/12AH), CL12400 (12V/40AH), CL12650 (12V/65AH) batteries or BAZR2
batteries of an appropriate rating.
Input:
• 220VAC (working range 198VAC - 256VAC),
50/60Hz.
Output:
• For output voltage and supply current refer to
eFlow104NV Series Power Supply Configuration
Reference Chart, pg. 2.
• Auxiliary output rated @ 1A (unswitched).
• Overvoltage protection.
Battery Backup:
• 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.
Fire Alarm Disconnect:
• Supervised Fire Alarm disconnect (latching or non-
latching) 10K EOL resistor. Operates on a normally
open (NO) or normally closed (NC) trigger.
Supervision:
• AC fail supervision (form “C” contacts).
• Battery fail and presence supervision
(form “C” contacts).
Supervision
(cont’d)
:
• Low power shutdown. Shuts down DC output
terminals if battery voltage drops below 70-75%
(depending on the power supply).
Prevents deep battery discharge.
Fuse Ratings:
• Refer to eFlow104NV Series Power Supply
Configuration Reference Chart, pg. 2.
Visual Indicators:
• Green AC Power LED indicates 220VAC present.
• AC input and DC output LED indicators.
Additional Features:
• Short circuit and overload protection.
• Unit is complete with power supply, enclosure,
battery leads, and cam lock.
