-----------------------------------------------------------------------------------------------------------------------------------------------------------
AUXILIARY SUPPLY - TERMINALS 1-2-3-4
supply’s section is carried out with double input 115 V nominal
for device supplying with 230 V, it is required to connect both sections in series
for device supplying with 115 V, it is required to connect both sections in parallel
-----------------------------------------------------------------------------------------------------------------------------------------------------------
LINK-FAIL MONITORING - TERMINALS 6-7
both terminals have to be connected between a isolated network’s phase and unipotential node (PE)
Maximum applicable voltage is 250 V (see insulation’s monitoring)
-----------------------------------------------------------------------------------------------------------------------------------------------------------
INSULATION’S MONITORING - TERMINALS 8-9
both terminals have to be connected between centre tap of secondary transformer or a isolated network’s phase and unipotential node (PE)
Maximum applicable voltage is 230 Vca so single phase networks could have max voltage of 230 V, three phase networks three wires
could have max voltage of 230 V phase-phase; but three phase networks four wires could have max voltage of 230 V phase-neutral
-----------------------------------------------------------------------------------------------------------------------------------------------------------
REMOTE PANEL’S CONNECTIONS PR5 - TERMINALS 10-11-12-13-14-15-16-18
connections for linking to remote panels PR5, Max voltage on these conductors is 24 V
-----------------------------------------------------------------------------------------------------------------------------------------------------------
SERIAL PORT RS485 (OPTIONAL) - TERMINALS 19-20-21
28 terminals A-B (19-20) head to serial bus, terminal C (21) is a mass’ reference that could be connected to eventual screen of cable RS485
Standard protocol used is modbus-rtu, documented in a specific handbook [IM833-U]
-----------------------------------------------------------------------------------------------------------------------------------------------------------
INPUT TEMPERATURE PROBE 2 (OPTIONAL) - TERMINALS 25-26-27
connections for linking to a temperature’s sensor - PT100 (EN 60751) or PTC (DIN 44081) sensor could be used.
In case of PT100 probes three wires, it is required to connect compensation’s conductor to the same terminal of correspondent conductor.
In case of PTC, it is necessary external resistor of 120 ohm min 1/4 W
-----------------------------------------------------------------------------------------------------------------------------------------------------------
INPUT TEMPERATURE PROBE 1 - TERMINALS 28-29-30
connections for linking to a temperature’s sensor - PT100 (EN 60751) or PTC (DIN 44081) sensor could be used.
In case of PT100 probes three wires, it is required to connect compensation conductor to the same terminal of correspondent conductor.
In case of PTC, it is necessary external resistor of 120 kohm min 1/4 W
-----------------------------------------------------------------------------------------------------------------------------------------------------------
INPUT FOR CURRENT MEASURE - TERMINALS 31-32
connection for external current transformer with secondary 5 A (current transformer ratio is programmable); if there is 3-phase network
must be used the special adapter type TSA-03 for 3 current transformer to permit to monitor in the insulation relay the highest value
of the 3-phase currents.
Only the module of the current value is measured (i.e. it is not important S1-S2 connection sequence).
-----------------------------------------------------------------------------------------------------------------------------------------------------------
OUTPUT AUXILIARY RELAY - TERMINALS 34-35-36
switch contact free from voltage and with programmable functions. Contact’s performance MAX 250 V 5 A resistive load
