Glossary of terms used in our user manuals
SNMP = Simple Network Management Protocol
LAN = local area network
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 ENCLOSURE AND ANY REPAIRS MUST
BE CARRIED OUT BY A QUALIFIED SERVICEPERSON.
Electrical Strength Tests
Components within the power supply responsible for providing the safety barrier between input and output are con­structed 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 techni­cians for advice regarding electric strength tests.
Earth Leakage
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 10oC 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 effi­ciency.
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 but all electrical equip­ment should be cleaned free of any dust accumulation at regular intervals. This is particularly important where internal fans are fitted.
Electromagnetic Interference (EMI)
Switching power supplies and converters inherently generate electrical noise. All 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 ratings
Check that the wiring and fuses or MCBs match the rating of the PSU or converter. Adequate fuse protection of battery circuits is very important owing to the large potential currents available from batteries. Our No-Break DC series has an internal ECB for protection of the battery circuit but for all other charging situations should have an external fuse or cir­cuit breaker fitted in the battery circuit.
Connection polarity
It is critical to check the polarity carefully when connecting batteries and equipment to DC power supplies and chargers. Boost chargers (and some float chargers) made by Innovative Energies have reverse polarity protection, which can be by an electronic switch (non-destructive) or an internal fuse which needs to be replaced if a battery is connected in re­verse.

The No-Break ™DC power supply is designed to provide DC power to lead acid batteries for critical back up applications. In addition to the normal features of the standard SR750C.. model, the SR750i….-LAN+ has an ethernet communication interface using SNMP protocol to enable user monitoring of the power supply and battery parameters and control of the battery condition test function.

The ECB is activated under the following conditions: 1. battery voltage drops below the Vdisco (1.66V/cell)
2. battery current overload (refer to graphs above)
The ECB will latch open only when there is no input power present. It will reset when input power is restored or can be manually reset by briefly shorting the

NOTES
1 Maximum current available with input power present: 2.5 x rated PSU current
with no input power: 1.5 x rated PSU current
2 Reverse polarity protection
If the battery is connected in reverse, the internal battery protection fuse may 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.
3 Battery Condition Test (BCT)
BCT function is disabled on start up and is controlled via the SNMP interface.
4 BCT fail reset If the system fails a BCT the BAT LOW alarm latches (de-energized state) until
either: both the mains power input and the battery are disconnected briefly or: the system passes the next BCT.
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 input power. “
POWER OK”
LED will light up. DC output voltage should appear at both load and battery outputs. 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. Both LEDs will light up. If this does not happen, 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
“BAT LOW”
alarm relay energises. The
“POWER OK”
LED stays on for about 30 seconds. 7 Connect load wiring to
LOAD
+ and
LOAD
- terminals.
8 The system is now ready for operation. 9 Please refer to separate user manual for setting up the SNMP web interface.

#2 1 x No-Break™DC charger and 2 x battery banks
The SR250xxxV No-Break™DC UPS is designed to provide superior battery backup availability without having to use two power supplies. Dual battery banks and automatic battery condition testing reduce the risk of battery failure for critical applications.
