Alternatively, to avoid induced voltage phenomena over floating command line, the
following wiring diagram may be used.

NOTES:
1. Supply from 110 to 240 V AC / 1-ph
L2 neutral
When L1 - L2 - L3 cables are long (more than 10 metres) induced voltage phenomena may occur on
floating command line
To avoid this unwanted effect, realize a cabling system where unused line (either L1 OPEN or
L3 CLOSE) is pulled to NEUTRAL line. To do this, a switch may be used.
For example with the BACO PN NC02GQ1, the following configuration may be used:
short circuit
pins 1 and 3
short circuit
pins 5 and 7
short circuit
pins 2 and 8
short circuit
pins 4 and 6
pin 3 = PHASE
pin 5 = NEUTRAL (L2)
pin 2 = OPEN (L1)
pin 4 = CLOSE (L3)
2. Contacts shown in intermediate position CLC1 - CLC2 end of travel signaling in CLOSING
Contacts shown in intermediate position OPC1 - OPC2 end of travel signaling in OPENING
3. Internal heater (max. 10 watt) is activated when a power supply from 110 to 240 V AC is connected to the
terminals 33-344
4. Output contact rating: 240 V AC / 5 A - 30 V DC / 5 A - 120 V DC / 0.5 A
