Precautions When Working With Batteries - Infinite Transtector ACINV Series Installation Manual

Installation Manual | ACINV Series 1RU Rack Mount Inverters
• Make sure that the chassis ground lug at the rear of the unit is solidly connected to the ground system of the rack or
cabinet in which it is installed.
• Keep the cables between the battery or other DC source and the unit as short as possible and twist them together
about 2 to 3 twists per foot. This will minimise radiated interference from the cables.
Problem and Symptoms Possible Cause

Display indicates OLP Overload condition
No output voltage Low / High input voltage
Input voltage fault
No output voltage Thermal shutdown
Display indicates OTP
Load <500W (1kVA unit)
Load <1000W (2kVA unit)
No output voltage Short circuit or wiring error
Display indicates OLP
Excessive load
If none of the above solves the problem please contact customer support, see inside front cover.
5. Important Safety Instructions
WARNING!
Before installing and using this inverter, be sure to read these
safety instructions.
Keep them in a safe place for future reference.
5.1 General Safety Precautions
5.1.1 Do not expose the Inverter to rain, snow, spray or dust. To reduce risk of hazard, do not cover or obstruct
the ventilation openings. Do not install the Inverter in a zero-clearance compartment as overheating may
result.
5.1.2 To avoid a risk of fire and electronic shock. Make sure that existing wiring is in good electrical condition; and
that wire size is not undersized. Do not operate the Inverter with damaged or substandard wiring.
5.1.3 This equipment contains components which can produce arcs or sparks. To prevent fire or explosion do not
install in compartments containing batteries or flammable materials or in locations where require ignition
protected equipment.
This includes any space containing gasoline-powered machinery, fuel tanks, or joints, fittings, or other
connection between components of the fuel system.

5.2 Precautions When Working with Batteries

5.2.1 Ensure the installer is familiar with the material safety data sheet from the manufacturer of the batteries
concerning safe use and medical treatment.

Solution
Use true RMS meter (See section 2.4.7)
Reduce load
Recharge battery, check connections.
Ensure ventilation openings are clean and
not obstructed.
Improve ventilation.
Reduce ambient temperature.
Check AC wiring for short circuit or
improper polarity (L and N reversed)
Remove load

5.2.2 NEVER smoke or allow a spark or flame in the vicinity of batteries.
5.2.3 Do not drop a metal tool on the battery. The resulting sparks or short-circuit on the battery or other electrical
part may cause an explosion.
5.2.4 Remove personal metal items such as rings, bracelets, necklaces, and watches when working with batteries.
Lead-acid batteries produces a short-circuit current high enough to weld a ring or the like to metal, causing
severe burn.
6. DIP switch settings
The follow tables define the various settings of the DIP switches mounted at the left side of the front panel of the Inverter.
Note that when changes are made to these settings it is necessary to recycle the power to the Inverter to allow
the internal microprocessor to read the new settings.

7. Communications Protocol & Remote ON/OFF Function
ACINV series inverters can communicate their status to a computer via an RS232 connection by sending a single 'Status
Inquiry' Telnet command from the computer as follows.
Using a Terminal programme such as Hyperterminal create a profile with the following parameters:
Baud rate: to match setting on unit (default 2400)
Data bits: 8
Parity: none
Stop bits: 1
Flow control: none
From the properties tab (in Hyperterminal) settings and then ASCII and make sure that all boxes are checked with the
exception of 'Force incoming data to 7-bit ASCII.
Make sure the profile is saved for future use.
