Wiring Relay Output Terminal
The surge voltage absorbing circuit should be installed for inductive load like relay
or contactor. For instance: RC absorbing circuit (please note that the leakage current
should be less than the working current of contactor or relay being controlled), VDR
or fly-wheel diode and etc. (For DC electromagnetic circuit, please pay attention to
the polarity at installation). The component of absorbing circuit should be installed
near the ends of relay coil or contactor.

Wiring Multi-function Output Terminal
Multi-function output terminals Y1 and Y2 can take 24V internal power supply of
inverter or external power supply as shown in Figure 3-14.
a: Internal power supply
b: External power supply

Wiring Analog Output Terminals
Analog output terminals M0 and M1 can represent various physical quantities when
connected to external analog meter. The specifications of jumper are taken as:
0~20mA output current or 0~10V output voltage, here M0 and M1 correspond to
JP1 and JP2 respectively. See the wiring of jumper and terminals in the following
table.
