WARNING
Risk of serious personal injury or damage to equipment and property! Always
observe the following:
Install and operate unit in a Restricted Access location, such as an enclosed
equipment rack
Operate the supply from a grounded 3-pin 120Vac or 230Vac outlet (50 or
60Hz) with a branch circuit breaker rated 20A or less
Always observe the following for applications requiring a back up battery:
Use only a Lead-Acid battery with rating and capacity appropriate for the
model of supply in use
Use an appropriate dc over-current protection device in line with the back-
up battery connection
Use a disconnect switch or circuit breaker in series with the battery
connection, to ensure installation and service is done with the battery de-
energised
Use wire and connectors rated for the maximum load current and size of
battery fuse or circuit breaker
Ensure battery polarity is correct before connecting
Do not attempt to charge a frozen battery
Handle batteries with care, never short circuit battery terminals
CAUTION
Risk of personal injury or damage to equipment! Always observe the following:
Install in a protected environment, keep sources of moisture away from unit
Ensure the total power consumption of the load does not exceed the
continuous rated capacity of the power supply output
Do not block air inlet or outlet openings in the unit
Do not place the power supply directly above or below an exposed battery,
due to possible presence of corrosive and/or flammable gasses
Do not add a ground connection to both battery and load, as this will bypass
the internal LVD relay

WARNING
Risk of serious personal injury or damage to equipment and property! Always
observe the following!
If a battery is used ensure the nominal battery voltage is correct for the
model of power supply, and that the battery positive is connected to the BAT
positive (+) terminal and the battery negative is connected to the NEG (-)
terminal.
Use an appropriate dc over-current protection device such as a fuse or
circuit breaker in line with the battery connection
Do not tie the POS and +BAT terminals together, as this will bypass the
internal LVD circuitry
Make any earth Ground connection to only a single LOAD or BAT terminal if
required. Do not ground both the load and battery as this may bypass the
internal LVD circuitry
AC input wiring to the Pro Series unit must be protected using an outlet with
a branch rated circuit breaker of 20A or lower value
Connection Diagram (Showing Rear Connectors and SW Switch 1-4)
Configure the Output Settings:
Always switch off the unit before changing the settings or making connections.
Choose a lead-acid battery with a nominal voltage rating (12/24/48V)
that matches the Pro Series rated output. Note that for good battery life
the battery should have a combined Ahr capacity of at least 3 times the
maximum charge current being used. (e.g. Use a 75Ahr or larger rated
battery (3 x 25A) with a 25A max charge setting)
Shown with battery backup/LVD, option B
Note: EARTH Ground connection may be made
to either load terminal

Set the max charge current to be supplied to the battery by setting SW
3, and SW 4 on the back panel according to the following chart: (note
that actual current flow to the battery may be less than the setting, and
is determined by the battery state of charge and temperature)

INSTALLATION
Mount the unit in a standard 19 inch equipment rack, (ensuring side air vents are
not blocked) using rack mounting screws (not supplied), then make the following
connections using wire and connectors appropriately rated for the maximum
input and output current rating of the unit:
Remove the plastic bus bar cover by removing the two screws holding it in
place
Connect the supply POS output bus bar to the load positive input (using a
supplied bus bar bolt/washer/nut set for the bus bar connection) (NOTE: do
not connect the load directly to the battery, as this will defeat the battery
charging and low voltage disconnect functions)
Innovative Circuit Technology Ltd. 7
Connect the supply NEG bus bar to the load negative input terminal (using a
supplied bus bar bolt/washer/nut set for the bus bar connection)
Connect a ground bonding wire from the chassis ground stud to the rack
On units with the optional battery back-up and LVD capability (model suffix
“B”):
o Choose a lead-acid battery with a float voltage rating that matches the
Pro Series output voltage, and has an Amp-hour (Ahr) capacity rating
greater than 3 times the max charge current setting of the power supply
(i.e. use a 75Ahr battery or larger on a 25A charge setting)
o Connect the battery negative to the supply NEG bus bar
o Connect the battery positive to an over current protection device (fuse
or breaker) and disconnect switch
o With the battery fuse removed or disconnect switch open connect the
fuse or switch to the supply BAT(+) terminal
o Either the POS or NEG load lead may be connected to earth ground if
required, but the internal LVD contactor is always connected to the
battery positive, as shown. NOTE: Do not ground the battery POS
terminal, as this may bypass the internal LVD relay
Connect the remote on-off control or unit form-C alarm contact monitoring
wiring to the REMOTE connector if needed, as shown in the following table:

REMOTE Connector: (use 22-26AWG wire)
Check that all connections to the power supply are correct and tight; re-install
the plastic bus bar cover using the original two screws provided.
Connect the AC power cord: Plug an approved AC power cord set rated for 15A
(120V) or 10A (230V) into the IEC type AC input connector on the back panel of
the supply (120V cord included with unit), then plug into a grounded 3 terminal
120Vac or 230Vac power outlet, with the front panel switch in the off position.
OPERATION
Switch on the unit using the front panel power switch, and observe that the front
panel green POWER LED is lit. Verify the supply output voltage using a hand held
8 Innovative Circuit Technology Ltd.
digital voltmeter. If a battery is connected install the external fuse and close the
disconnect switch.
On units with the battery back-up option connected switch off the ac power, and
use a hand held digital voltmeter to verify that the battery voltage is provided to
the output load terminal. Switch AC power back on, and verify the output supply
voltage rises to the normal output rating as the battery charges.
The unit can now be left operating normally. As long as the external back-up
battery voltage is greater than the low voltage disconnect (LVD) level the battery
will be connected directly to the supply output and will instantly power the load
in case of an AC power failure. With AC power off the battery will then gradually
be discharged by the load. When the battery voltage drops below the LVD
disconnect level the internal relay will open, preventing the battery from being
excessively discharged.
When AC power returns the supply will close the LVD relay and charge the
battery to bring the voltage back up to the float voltage level. Battery charge
current is limited to the maximum rate determined by the charge current setting
of SW 3 and 4 (see table on page 5), while the output voltage will be determined
by the battery state of charge, and will rise to the output float voltage over time.
The battery will be maintained at the supply output (float) voltage level until AC
power is removed.
Batteries connected directly to the supply output (not using the LVD option BAT
terminal) will be charged to the supply output voltage level with a current limited
to the maximum supply output rating.
The remote shutdown input may be used to disable the supply output by
applying a voltage from 2.5 to 16V, and the form-C alarm contacts can be used to
remotely monitor fault conditions per the Status Indicators and Alarms table.
PARALLEL OPERATION
Up to 3 matching units without the optional battery backup capability may be
connected in parallel to power higher current loads. The unit with the highest
output voltage will initially provide most of the load current, and as load current
increases the current supplied will tend to balance between the parallel units.
CAUTION
Risk of damage to equipment!
Ensure battery current supplied through the optional internal LVD contactor
cannot exceed the current rating of the unit
Do not use the internal LVD contactor for parallel applications where load
current can exceed the maximum rating of a single unit
