Throughout the installation phases and operation of this equipment,
safety procedures take precedence over all other activities. As a minimum:
1. Read and follow all instructions in this IOM.
2. Before handling electrical connections, disconnect power feeds. There may be
multiple power feeds connected to this unit. Proceed carefully when opening the
cabinet cover.
3. Risk of electric shock! All wiring must be in accordance with applicable local
codes, regulations and the NEC. Be aware that there may be hazardous voltages
present which can shock, burn, or possibly cause permanent injury or even death.
This is a stored energy system. This device is designed to supply backup power
when mains power is lost or disconnected. Terminals are live whenever the
battery is connected.
Safety First!
Handling & Storage:
This product contains a lead-acid battery storage system. It
is designed as a backup power supply for industrial electric
actuators. The enclosure is a weather-resistant NEMA4X
polycarbonate enclosure with a clear hinged door. Care must be
taken during shipping and handling to prevent damage to any
of the components or the enclosure. It contains logic control PC
boards, various discrete electronic components and electrical
storage devices, all of which are susceptible to damage from
high humidity environments. For this reason, this device must be
protected from direct contact with water and/or high humidity
storage environments.
Protect the device from physical damage while awaiting the
completion of installation processes.
Product shipping information:
The EFS system is packaged in two separate boxes inside one larger
shipping carton. This is done to prevent shipping damage to both the
polycarbonate enclosure as well as to sensitive components associated
with the heavier control panel and battery back up system.
1. BOX 1 contains the berglass enclosure. Do NOT use sharp
objects when opening the carton as you may damage the clear
lexan door attached to the enclosure cabinet.
2. BOX 2 contains the main face plate panel, battery system and
control electronics.
3. This unit is shipped with the battery system disconnected.
Follow the instructions below to correctly reconnect the battery
to the power unit. Failure to follow the connection sequence will
prevent the battery unit from starting.
4. Do NOT mount the panel in the cabinet until instructed to do so.
Installation:
1. Mount the cabinet either indoors or outdoors protected
from direct sunlight or other high heat sources. The cabinet
mounts with the latches to the RIGHT, and hinge to the LEFT.
The suggested EMT entry location is shown on page 18 in
the dimensional drawing. Make all conduit penetrations per
local code and perform all wire pulls prior to installing the
main control panel.
2. The enclosure must be mounted onto a stable, vibration-
free structure. The control panel is very heavy, and unstable
platforms my cause the panel to dislodge from the enclosure.

3. After the enclosure is properly mounted, install the four corner standos using
a 3/8” socket or a nut driver. There are two (2) 3”long hex standos connected
together for EACH corner of the enclosure. These are located inside the
enclosure when shipped. (see Fig 1). DO NOT OVERTIGHTEN!
4. Turn the main panel over to reveal the back side of the plate. Remove the
sliding battery compartment cover from the APC unit. (see Fig 2).
5. Tilt the entire assembly to slide the battery partially out of the enclosure. This
will give you access to the battery terminals.
6. Connect the positive (red) wire to the red battery terminal. The black terminal
and wire should already be connected. (see Fig 3).
7. Slide the battery back into the enclosure, and replace the slide cover. Take care not to
pinch the battery wires in the process. (see Fig 4).
8. After the battery is installed, take care NOT to press the recessed START button on
the APC unit. If it gets pressed, the APC unit will start and it will immediately start
generating 120vac power on several of the screw termninals, which makes the panel
rather dicult to handle. If the START button gets pressed accidently, you can press for
a few seconds again to shut o the generator. (see Fig 5).
9. Install the panel onto the four stando posts from step 2 (above) using 10-32 x 1/2”PH
screws from parts bag. (see Fig 6).
10. Make wiring connections (see pages 6-16).

1. After installation and wiring are complete and the battery has
been connected, apply power and PRESS the START button to
enable the battery system. There is LIVE voltage present on the
back of the main panel as well as on the terminal block, even after
the main power has been disconnected. Handle appropriately!
2. Place the FAIL POSITION SELECTOR switch in the desired mode
(Fail OPEN or Fail CLOSED) based on the requirements of the site.
3. Indicator lamps show when Power is applied, which Fail position
has been selected, when the Battery is Charging, and when the
system is running on Battery Power.
4. Units are equipped with end-of-travel (EOT) indicators that will
function if interface wiring has been connected to the actuator.
Open End of Travel and Closed End of Travel LED’s will illuminate
when the actuator has reached its respective end of travel
position.
5. The Line Status and Battery Status are dry form C contacts rated
at 8A, 250 vac/30vdc. Line status is CLOSED when mains power
is applied. Battery system status is CLOSED when the EFS battery
charge is operational.
6. Overloading the backup system will TRIP the breaker. This is a
PRESS to RESET type and is NOT self resetting.
7. It is possible to connect multiple actuators to a single EFS
PROVIDED THE TOTAL ACTUATOR DEMAND DOES NOT EXCEED
THE RATING OF THE EFS. Reference page 4 for details and contact
Max-Air Technology for assistance.

EFS Series Sequence of Operation - Open/Close/Jog Actuators
The electronic fail-safe system (EFS) is wired in series between the mains power and the actuator. Under normal operation, 120VAC power supplied to the EFS
H & N terminals will illuminate the white“LINE IN”indicator light, and provide charging voltage to the battery system.
While Mains power is present, the remotely generated analog control signal (either 2-10vdc or 4-20mA) is passed through the EFS and on to the actuator. The
actuator will follow that control signal. While under mains power the blue“BAT CHARGING” indicator light will illuminate and the yellow“B/U POWER” indicator
light will be o. While under mains power, the positon of the“FAIL POSITION SELECT”switch is irrelevant. Power is supplied through the back-up system cabinet
and the actuator heater is enabled. No current is being drawn from the battery system during this mode of operation. Optional indicator lights can be wired to
show actuator end of travel status. These lamps are active as long as the battery system is running or Mains power is present. Optional STATUS contacts can be
used for remote health indicators of LINE voltage coming into the EFS and if the Battery System is operating.
When the mains power is lost, charging power is no longer supplied to the battery system. The green“LINE IN”indicator light is turned o, and the battery system
automatically generates modied-sine wave line voltage to provide power for the transformer to generate 24v actuator power. The blue“BAT CHARGING”indicator
light is turned o, and the yellow “B/U POWER” indicator light is turned on. The “FAIL POSITION SELECT” switch becomes active, and depending on its position,
drives the actuator either fully OPEN or fully CLOSED via its own signal generator. During this mode of operation, the remote analog control signal (if present
or not) is irrelevant. The battery system will provide ample power to drive the actuator more than 5 full torque cycles. However, once the actuator reaches its
end-of-travel limit switch, power drain from the back-up system is reduced to the requirements of the yellow “B/U POWER” indicator light and the transformer
eddy current draw (up to 10% of rated load).
The battery system will provide ample power to drive the actuator more than 5 full torque cycles. However, once the actuator reaches its end-of-travel limit
switch, power drain from the back-up system is reduced to the requirements of the blue “B/U POWER” indicator light.
After 15 minutes, the battery system turns itself o and waits for the mains power to return.The design of the Max-Air ME & MX series actuators provides automatic
locking of the actuator position after the battery system shuts down. Normal operation is resumed when mains power returns.
