ICT N+1 REDUNDANT SERIES
INSTRUCTION MANUAL
Incorrect wiring, such as reverse battery connection, may result in
serious damage to both the N+1 system and equipment connected to
the system.
Do not block any of the vents on the outside of the unit.
Servicing of the unit should be done by ICT.
Ensure that the two voltage selector switches are both set correctly and
to the same position. If the switches are incorrectly set it will result in
module failure.
The system must be operated from an outlet with a proper grounding
connection.
If replacing modules, disconnect power from any external source
including the AC cord and any connected batteries.
WARNING: High leakage current, use only cord set provided with this
equipment.
ICT N+1 REDUNDANT SERIES
SETUP
WARNINGS
The ICT N+1 Redundant Series is a high reliablity, expandable DC power system. The system is designed with active current sharing technology to
distribute the load current among the modules, reducing stress on individual components and increasing reliability. Each module is equipped with a
high power shottky output diode for true redundancy.
This series comes standard with system monitoring functions through a D-Sub connector, with signals such as module ok, over temperature
warning, analog DC output current, fan failure, and AC fail. Battery backup terminals are provided for float charging an external lead acid battery and
providing battery revert capability.
These instructions should be read before using the product and it should be saved for future reference. A more detailed manual is available on
request from ICT.
For 120V operation, set both voltage selection switches to the
120V position. For 220V operation, set both to the 220V
position.
After the system has been mounted, connect the load to the
terminal block at the rear of the unit. If desired, connect a 12V
or 24V lead acid battery (matching the N+1 system voltage) to
the battery terminals for float charging.
A disconnect device must be provided for both the DC power
output circuit and the battery backup circuit if used. The
backup battery (if used) should be provided with an overcurrent
device suitable for the available short circuit current of the
batteries used.
Connect the AC power cord to the unit and then to the available
outlet. Alternate AC cord types are available.
Turn the power switch on the front of the unit to the on
position.
