2.2.3 Terminal connection diagram

(1) Wiring
1. Both the CM1 and L terminal is insulated to both the common terminal of the input and output
signals.
Do not short or earth these common terminals.
2. Use twisted screened cable, for the input and output wires of the control circuit terminals.
Connect the screen to the common terminal.
3. Limit connection wires to 20m. When it is necessary to wire over 20m, use a VX applied
controller RCD-A (Remoter operation bar) or a CVD-E (Insulated signal transducer)
4. Separate the control circuit wiring from the main power and relay control wiring.
5. If control and power wires must cross make sure they cross at 90 degrees to each other.
6. When connecting a thermistor to the TH and CM1 terminal, twist the thermistor cables sepa-
rate from the rests. Limit connection wires to 20m.
7. When using relays for the FW terminal or an intelligent input terminal use a control relay as
they are designed to work with 24Vdc.
8. When the relay is used as an intelligent output, connect a diode for surge protection parallel
to the coil.
9. Do not short the analogue voltage terminals H and L or the internal power terminals PV24
and CM1. There is risk of Inverter damage.
