Note:
1. Electric characteristics are based on the condenser suction air temperature at 32°C, evaporation temperature -10°C and condensing unit inlet superheat degree
10 deg.
2. Figure in [ ] of the minimum wire size shows the maximum wire length (m) with the voltage drop at 2 V.

3. Signal cable connection procedures for connecting Module controller
• Signal cables use DC 5 V. Never connect wires for 400 V. It trips the protective fuse on the PCB.
-Confirm that it is so arranged that 400 V power will not be applied to signal cables.
-Check the resistance of signal cable terminal board before turning power on . If the resistance is 100Ω, or less, a power cable may be connected to the
signal cable terminal board.
• Communication method is based on RS485.
• Connect signal cable to A, B on the terminal board.
• Signal cables has the polarity. Connect them as shown in fig. 24.
External signal output
Part of operating states can be output from the controller of condensing unit.
1. Alarm signal
:
If the condensing unit stops under abnormal condition, an alarm signal is released.
2. Compressor operation signal
:
Signals of compressor operation and stop can be extracted.
- Extract signals via a relay.
Where the power for the relay contacts is taken from a terminal box, connect the wires as shown by the electric wiring in the next section.
