I.C C3C-12-40-48 or C3C-24-25 Converter Front Panel Indicators
There are 3 LED indicators on the front panel indicate the operational state of the converter.
The green LED indicates that input power is connected to the unit and that the primary stages of the converter are
operating.
The yellow LED indicates a non-urgent alarm state within the converter.
This could be caused by the following:
Converter in output power/current limit
•
Converter over temperature
•
Fan failed
•
Converter soft starting
•
The red LED indicates an urgent alarm state within the converter.
This could be caused by the following:
Converter failed
•
The DC input voltage is outside the operating range
•
Converter shut down due to output over-voltage or over-temperature
•
Appendix II AC I
Information to assist the installer for AC input protection is detailed in this section.
Illustration A: Surge Protection Installation
Illustration A shows the surge protection installation principles, utilizing the 3 stage protection zone concept.
The Type 1 (SPD1) surge arrester, fitted in the installation's main incoming electrical switchboard, is capable of diverting the
energy of a direct lightning strike. This is the first stage of the electrical network's protection. It is important that upstream
Type 1 protection is provided on site. Although the actual surge capability of the device used can vary depending on the
severity of lightening in any particular installation, the typical maximum discharge current of a Type 1 surge suppressor will
be in the order of 50kA to 100kA (10/350µs impulse)
The 10/350µs current wave as shown below is the standardized current waveform which passes through equipment when
subjected to an overvoltage due to a direct lightning strike.
