Safety
The user is responsible for ensuring that input and output wiring segregation complies with local standards and that in
the use of the equipment, access is confined to operators and service personnel. A low resistance earth connection is
essential to ensure safety and additionally, satisfactory EMI suppression (see below).
HAZARDOUS VOLTAGES EXIST WITHIN A POWER SUPPLY EN LOSURE AND ANY REPAIRS MUST
BE ARRIED OUT BY A QUALIFIED SERVI EPERSON.
Electrical Stren th Tests
Components within the power supply responsible for providing the safety barrier between input and output are con-
structed to provide electrical isolation as required by the relevant standard. However EMI filtering components could be
damaged as result of excessively long high voltage tests between input, output and ground. Please contact our techni-
cians for advice regarding electric strength tests.
Earth Leaka e
The EMI suppression circuits causes earth leakage currents which may be to the maximum allowable of 3.5mA.
Ventilation
High operating temperature is a major cause of power supply failures, for example it has been well documented that a
10
o
C rise in the operating temperature of a component will halve its expected life. Therefore always ensure that there is
adequate ventilation for the equipment. Batteries and cooling fans also suffer shortened lifetimes if subjected to high
ambient temperatures - both should be included in a routine maintenance schedule to check for signs of reduced effi-
ciency.
Water / Dust
Every effort must be made in the installation to minimise the risk of ingress of water or dust. Water will almost always
cause instant failure; the effects of dust are slower in causing failure of electronic equipment. All electrical equipment
should be cleaned free of any dust accumulation at regular intervals.
Electroma netic Interference (EMI)
Switching power supplies and converters inherently generate electrical noise. Power supply wiring should be as short
as practicable and segregated from all equipment wiring which is sensitive to EMI. Residual noise can be reduced by
looping DC wiring through ferrite cable sleeves. These are most effective as close to the power supply as possible and
as many turns of the wire taken through the core (+ and - in the same direction) as the core will accommodate.
Fuse ratin s
Check that the wiring and fuses or MCBs match the rating of the PSU or converter. Note that the Innovative Energies
No-Break
TM
DC chargers are able to deliver up to 2.5 times the rated current when mains power is on.
Connection polarity
It is critical to check the polarity carefully when connecting DC devices. Some Innovative Energies models have re-
verse polarity protection (RPP), for example, the Smartchargers have electronic (non-destructive) RPP, the No-
Break
TM
DC range has an internal fuse which needs to be replaced if the battery is connected in reverse. Usually, how-
ever, a reverse polarity connection results in instant destruction of the device, especially if there is a battery involved.

The No-Break™ DC power supply is designed to provide DC power and float charge lead acid batteries for
critical back up applications. The SR250i  485 is a variant of our standard SR250C model. In addition
to all the normal features of the No-Break™ DC range, the SR250i  485 has a serial communication inter-
face to enable user monitoring of the power supply and user control of the battery condition test function.

ONNE TION DIAGRAM
ONNE TION & INITIAL TESTING
1 Check input and output voltages of system, ensure that they match the equipment. All loads should be
isolated.
2 Check polarity of all wiring. Place temperature sensor probe near or on batteries.
3 Plug in ac input and turn power on. Both LEDs will light up after approx. 4 sec, “BATTERY” LED will
go out after another 10 sec (since there is no battery connected). DC output voltage should appear at both
load and battery outputs (ensure screws are tightened down on the connector block).
4 Turn off input power.
5 Connect battery.
6 Check that ECB (internal electronic circuit breaker) closes by shorting together the BATTERY –ve and
LOAD –ve terminals briefly. You will hear a relay operate and both LEDs will light up. If this does not hap-
pen, there is a fault in the wiring or the internal battery protection fuse is ruptured (see Note 2 below). The
battery voltage will then appear at the load terminals and the “BATLOW” alarm relay energises. The “MAINS
FAIL” LED stays on for about 30 seconds.
7 Connect load wiring to LOAD + and LOAD - terminals.
8 Turn on ac power.
After the batteries are fully charged, check that the battery continues to power up the load when the
input power is turned off.
10 Connect power (10-30VDC) to the protocol converter, the red LED (“supply on”) will light up
11 Connect RS485 communication port on SRxxx i to MODBUS protocol converter (+PROTOCONMB).
The green LEDs on both the power supply and the converter will flash to indicate that the comms. are
working.
12 Connect the programming cable between the converter and your PC. It is better to use a computer
with a DB serial input as some serial to USB converters do not work. For instructions on the protocol
converter please refer to page 10.

ALARMS
AUX: This relay is energized when BCT is in progress unless otherwise requested.
MAINS FAIL: De-energized on loss of mains input power
NOTE: 30 second delay
BAT LOW: De-energized when either:
1. battery voltage = 1.8V/cell (for 2V cells) - operates only when no mains power
present or
2. battery missing or fault in battery circuit wiring (alarm does not activate for up to
battery detection interval time).
REVERSED POLARITY ONNE TION OF BATTERY
If the battery is accidentally connected in reverse, the internal battery protection fuse will be ruptured and the
unit should be returned to the manufacturer for repair. If the fuse is good, the voltage measured as at step 3
above should be exactly the same on both the load and battery outputs.

BATTERY ONDITION TEST
The BCT function is enabled by an internal jumper as supplied
from factory unless otherwise requested. Refer to the photo to
the right for the position of this jumper. It must be removed to
disable the automatic BCT. Although the BCT may be enabled/
disabled via the communication port, this software determined
state is not retained if the PSU is disconnected from both the
mains input and the battery.
B T FAIL RESET
If the system fails a battery condition test the BATT LOW alarm
latches (de-energized state) until
either: both the mains power input and the battery are discon-
nected briefly
or: the system passes the next BCT.
