Delta M88 Series Operation And Installation Manual Download Page 39

Page: 39 / 192

The communication module of M88H provides VCC, RS-485, dry contact, EPO,

and Digital Input terminals for different use.

3.5 Communication Module Connections

Figure 3-27 : Communication Module

The pin definition of RS-485 is shown in the following table. Different RS-485

connection requires different set up for the terminal resistor.

• When single inverter is installed, the terminal resistor on its communication

module should be switched ON.

• When several inverters are cascaded, only the first and the last inverter’s

terminal resistors MUST be switched ON.

3.5.1 RS-485 Connection

In order to have good transfer quality, twisted-pair wire is recommended to be

used as communication cable.
