2.2
Device and application-specific safety instructions
• During operation, the communication module must be firmly connected to the inverter.
• Only use cables that meet the listed specifications.
Specification of the CAN bus cable
• Decouple your Ethernet home network from the system network for Ethernet-capable Lenze
devices, in order to prevent Ethernet communication faults.
• Before switching on the mains voltage, check ...
• the entire wiring for completeness, short circuit and earth fault:
• whether the bus system is terminated through a bus terminating resistor at the first and last
physical bus station.
2.3
Residual hazards
Device protection
• The communication module contains electronic components which may be damaged or
destroyed by electrostatic discharge.
• To prevent the RJ45 socket from being damaged, insert or remove the Ethernet cable connector
straight (at a right angle) into or from the socket.
• Observe the following to prevent any damage to the plug-on terminal strips and contacts:
• Wire the plug-on terminal strips first, then plug them on.
• Plug-on terminal strips that are not assigned must also be plugged on.
Documentation for the inverter, control system, system/machine
All the other measures prescribed in this documentation must also be implemented.
