1. General Safety Instruction
1.1 Safety Instruction
As dangerous voltage and high temperature exist within the charge controller, only qualified and
authorized maintenance personnel are permitted to open and repair it.
This manual contains information concerning the installation and operation of the charge
controller. All relevant parts of the manual should be read prior to commencing the installation.
Please follow the local stipulation meantime.
Any operation against safety requirement or against design, manufacture, safety standard, and are
out of the manufacturer warranty.
1.2 General Precaution
1.2.1 Do not expose to rain, snow or liquids of any type，it is designed for indoor use.
1.2.2 To avoid fire and electric shock, make sure all cables selected with right gauge and being
connected well. Smaller diameter and broken cable are not allowed to use.
1.2.3 Please do not put any inflammable goods near to charge controller.
1.2.4 Never place unit directly above batteries, gases from a battery will corrode and damage the
charge controller.
1.2.5 Do not place battery over charge controller
1.3 Precaution regarding battery operation
1.3.1 Use plenty of fresh water to clean in case battery acid contacts skin, clothing, or eyes and
consult with doctor as soon as possible.
1.3.2 The battery may generate flammable gas during charging. NEVER smoke or allow a spark
or flame in vicinity of a battery.
1.3.3 Do not put the metal tool on the battery, spark and short circuit might lead to explosion.
1.3.4 REMOVE all personal metal items such as rings, bracelets, necklaces, and watches while
working with batteries. Batteries can cause short-circuit current high enough to make
metal melt, and could cause severe burns.

2. Introduction
iDU is a DC UPS integrating multiple functions into one unit, including a smart battery charger,
battery monitor and the load management. The built-in professional adaptive charging algorithm
with automatic temperature charging makes it suitable for composing a power backup system for
various outdoor equipments, such as DAS, RF and FTU etc.

 When AC grid is available, iDU offers 3 steps smart charging to the battery. At the same time,
it offers the power supply to the load.
 When AC grid is not available, battery offers the energy to the loads. iDU alarms via dry
contact.
 When battery discharged until the low voltage protection level, iDU cut off the output of
battery and alarms via dry contact.
 When the battery in the floating state for a long time, in order to avoid plate passivation, the
module will automatically periodically activation process, at the same time also provide
remote manual activation interface and local activation key, convenient for the user to control
the active state.
Features:
 Power factor correction.
 Professional temperature compensated battery charging control.
 Working temperature: -40℃-70℃.
 Low power consumption.
 Self- cooling design.
 IP55 design.
 System data monitor via RS484 communication.
 Real-time power supply data.
 Real-time alarm data.
 Real-time battery data, including battery voltage and discharging current.
