INTRODUCTION:
Thank you for selecting Indelac Controls, Inc. (ICI) for your UPS / Battery Backup System needs. We at ICI are
proud of our products and feel confident they will meet or exceed your expectations of quality and reliability.
Every precaution has been taken to insure that your equipment will arrive undamaged; however, accidents do
occur. Therefore, the first thing you must do upon receipt of your package is to inspect it for damage. If the
box is damaged there is a possibility that the equipment inside the box may be damaged as well. If this is the
case YOU MUST FILE A CLAIM with the delivering CARRIER. All shipments are F.O.B. our factory and it is
YOUR RESPONSIBILITY to file a claim for damages.
NOTE: ICI’S ELECTRIC FAIL-SAFE DEVICE MAY BE USED WITH OTHER BRANDS
OF ELECTRIC ACTUATORS - ACTUATOR TERMINAL CONNECTIONS WILL NOT
BE THE SAME. CONTACT SALES TO VERFY APPLICATION FIT.
STORAGE:
If the Fail-Safe Device is scheduled for installation at a later date:
1. Store off the floor protect with unsealed cover allowing for side and bottom ventilation. In the
event that the unit is going to be stored where there is insufficient temperature control internal
heaters must be installed and energized to protect the unit from condensation and extreme
temperature variations.
2. Store in a climate controlled building.
3. Store in a clean and dry area.
4. See the Maintenance Section in this Manual for Proper Care of the Battery.
FOR FUTURE REFERENCE RECORD:
1. Fail-Safe model number
2. Fail-Safe enclosure type NEMA 4_____, NEMA 4X_____, NEMA 7_____.
3. Fail-Safe output Voltage
4. Fail-Safe serial number
5. Date of installation Put into operation

PRODUCT DESCRIPTION:
The Indelac Controls Electric Fail-Safe Device provides battery backup power to your actuator in the
unlikely event that the Factory or Facility Mains Power should go down. These devices are designed to
seamlessly convert 12vdc, 24vdc or 36vdc battery standby power to 115vac or 230vac to power your
actuator. The battery power supplies an internal Power Inverter that converts the DC to AC to run the
actuator to the user wired Fail Position when the Mains Power fails. When normal Mains Power is present,
it powers the actuator and provides a maintenance charge to the backup battery. When the Mains Power
fails or drops out momentarily, the Power Inverter will automatically switch over to battery power and
supply a PWM sine wave AC to the actuator. When the Mains Power comes back online, the Power
Inverter will immediately transfer Mains Power back to the actuator and proceed to re-charge and maintain
the battery.
The Electric Fail-Safe Devices come in a variety of styles and sizes to fit the smallest to largest of
actuators. Indelac provides these Devices in NEMA 4, NEMA 4X or NEMA 7 enclosures to provide 5, 7,
10, 15 or 30 Amps of output power. Each Fail-Safe Device is designed to supply the actuator’s continuous
Full Load Ampere draw to drive the Actuator to the Fail-Safe position. The Power Inverter can also supply
the additional current required for start-up / Locked Rotor Ampere Torque for up to the initial 1-2 second
turn on.
The internal Power Inverter has a built in 3 Stage Battery Charger for the on-board Sealed Lead Acid
Battery. Depending on the size & age of the battery used in each Fail-Safe Device, battery charge time
can vary from hours to overnight for a full charge.
Optional features, such as Emergency Disconnect Switches, Internal Heaters and Internal Relays to run
more than 1 actuator to Fail Position may be ordered –Consult the Factory for available SPECIAL
Options.

WIRE SIZING AND LENGTHS:
Indelac recommends the Installer follow the wire gauge chart shown below when connecting the Fail-Safe
Device to the actuator. The Fail-Safe Device should be mounted at the shortest distance possible to the
actuator to assure best possible performance. Indelac DOES NOT recommend that the Fail-Safe Device
be mounted any further than 100 feet from the actuator.

WARNING!
WIRING MUST CONFORM TO ALL STATE AND LOCAL ELECTRICAL WIRING CODES.
THIS DEVICE SHOULD BE INSTALLED BY A LICENSED ELECTRICIAN.
IMPROPER POWER CONNECTION CAN RESULT IN DAMAGE TO THE COMPONENTS OR SERIOUS
INJURY TO THE INSTALLER.
VERIFY THAT ALL WIRES ARE DE-ENERGIZED BEFORE MAKING ELECTRICAL CONNECTIONS!
WIRE GAUGE
NOTE: For all wiring, make sure the connectors and wires are fully seated after making all wiring
Connections and Screw Terminals are tight!

ELECTRICAL CONNECTIONS & WIRING DIAGRAMS:
All wiring is to be completed through the conduit openings using the appropriate conduit –Refer to your
local electrical codes. Open the Fail-Safe Device door by turning the latch counter-clockwise using a flat
head screwdriver. To Open the Door on the NEMA 7 enclosure, ALL of the outer Door bolts need to be
removed before Opening at the hinge. Connect the Main Power to the Fail-Safe Device & connect the Fail-
Safe Device to the actuator per the appropriate wiring diagram below. Assure that the power wires are DE-
ENERGIZED!
Mount the Fail-Safe Device to a solid surface using the appropriate hardware. These units are heavy and
using hardware that is not appropriate or too small may cause the Fail-Safe Device to separate from its
mounting and become damaged. See the Part Number Specifications Section for dimensions and weights.
NOTE: Two (2) conduit openings are supplied in the cabinet housing of the Fail-Safe Device.
One opening is for the incoming AC power wires and the other is for the Outgoing Power wires
to the actuator. All wires are to be securely tightened into the Customer Connections Terminal
Block.
5 Amp NEMA 4X Version Shown, Internal Connections View
CAUTION: Make sure that the wires are DE-ENERGIZED BEFORE making any electrical
connections. Serious damage to the components or serious injury/death may occur.
Also verify that the proper voltage and wiring is being connected to the Fail-Safe Device and
matches the required input of BOTH the Device and the Actuator.

5AMP 120VAC FAIL-SAFE DEVICE WIRING/CONNECTION DIAGRAM
Wiring diagram shows the Actuator wired for FAIL CLOSE –the Fail Terminal #7 is wired to the CLOSE Terminal on the
Actuator. When the incoming Mains Power Fails or is shut OFF, Terminal #7 will be energized HOT to drive the
Actuator to the CLOSE Position. This Terminal #7 may also be connected to the OPEN Terminal on the Actuator to
drive the Actuator OPEN when power fails.
