Uninterruptible power supply with integrated battery
ICAD-UPS is dedicated for use along with ICM sizes 20-150 installed
with ICAD 600A and ICAD 1200A actuators.
In the event of power failure, there is a need to make sure that the
ICM goes to a safe position.
Danfoss ICAD-UPS can be connected to the ICAD 600A / 1200A.
The solution ICM with ICAD connected to ICAD-UPS with default
speed and boost value (
i
30
and
i
31
) will give one of the following
possibilities in the event of power failure:
– close ICM
– open ICM
– stay
– go to a specific ICM Opening Degree
When power supply has been re-established the system will
automatically return to normal operation.
The uninterruptible power supply (UPS) is equipped with an
integrated energy storage system. The internal energy storage
system is monitored continuously by the battery management
system.
Features
• UPS with integrated energy storage
• Integrated temperature sensor for optimized battery charging
• Energy storage system
Safety and warning instructions
Only professionals may install and start up the device. Regulations
specific to the country must be observed.
• Never carry out work on live parts
• Establish connection correctly and ensure protection against
electric shock
• Use a current-limited source or a suitable fuse (≤15 A)
• When connecting the individual battery blocks, ensure the
correct polarity and avoid short circuits on the pole terminals
• Following installation, cover the terminal area to prevent
accidental contact with live parts (e.g., installation in a control
cabinet)
• Observe mechanical and thermal limits
• The location must allow for sufficient ventilation
• Keep flames, embers or sparks away from the module
• When changing the battery, use only battery blocks of the same
type with the same batch number
• The battery blocks are maintenance-free and may not be
opened
• When storing the UPS, pay attention to the latest startup date
of the battery set, and recharge the battery set if necessary
• Prior to transporting the UPS, remove the DC fuse in the battery
compartment
• Do not disconnect the DC fuse and/or the battery wiring under
Hazloc conditions
Initial charging of the battery
Prior to starting the UPS up in your application, connect the
UPS to a voltage source and charge the battery set for
24 hours.

1.1 LED status indicators/LED bar graph
The UPS status is displayed via LEDs in different colors and flash
sequences.
The floating switching outputs switch depending on the current
device status.
2. Opening/closing the battery compartment (fig. 3)
• Press the locking buttons on the battery compartment
• Carefully remove the battery compartment cover
• You can now carry out the work to be done
• Then press the battery compartment cover onto the locking
latches
3. DCC fuse (fig. 4)
The UPS is equipped with an internal pluggable DC fuse as
protection during transport and for protecting the cabling.
Always remove the DC fuse prior to transporting to the UPS.
To start up the UPS, plug the DC fuse back into the fuse
holder.
A faulty/blown DC fuse must be replaced by a fuse of the
same type.
4. Battery connecting cables (fig. 6)
Check the battery wiring for the individual battery blocks
for the correct polarity and color coding.
508:
Use copper cables for operating temperatures of
> 75 °C (ambient temperature < 55 °C)
> 90 °C (ambient temperature < 75 °C)
60950:
Use ferrules for flexible cables
Tighten screws on all unused terminals
A. Suitable for a max. altitude of 2000 m
B. Suitable for indoor use only
C. Clean only with water
D. Power source shall be double isolated from hazardous voltages
E. Protection may be impaired if the equipment is used in a manner
not specified by the manufacturer
F. This equipment is suitable for use in class I, Division 2, Groups A,
B, C and D or non-hazardous locations only
G. For all models the following end-product enclosures are
required: Mechanical, Fire, Electrical
H. Warning - Explosion hazard - Do not disconnect equipment
unless power has been removed or the area is known to be free
of ignitable concentrations
I. Note - Explosion hazard - Substitution of components may
impair suitability for use in potentially explosive areas
(CLASS 1; DIVISION 2)
J. Warning - Explosion hazard: Do not replace fuse unless power
has been switched off or the area is known to be
non-hazardous
K. Warning - Explosion hazard: Do not remove or replace battery
while the circuit is live or unless the area is known to be free of
ignitable concentrations
Notes on disposal
Do not dispose of used batteries in the household waste!
Dispose of these according to the currently valid national
regulations.
