51
2.6 Instruction for Installation
Do not install or remove the CANopen communication Module while the power
supply of the equipment is ON. Otherwise, both the CANopen communication
Module and the inverter may be damaged. Install or remove the CANopen
communication Module when the condenser of the inverter has been fully
discharged.
Do not change the connection of communication signal wire while the inverter
power is on.
Make sure that the inverter terminal and the connector of the option board are
in agreement.
When building a network, make sure to connect the terminal resistance to the
CANopen communication Module at the end position. The terminating resistor,
a 120 ohm 1/2W resistor, should connect the CAN_L and CAN_H.
2.7 Maximum Communication Range according to Baud Rate
In a network system, the total length of the network line is determined by the
baud rate. The performance of the communication farther than this distance is
not guaranteed.
