App. 4.4 Electrical Installation and configuration diagram
WARNING
Turn off the molded-case circuit breaker (MCCB) to avoid electrical shocks or
damages to the product before starting the installation or wiring.
CAUTION
The installation complies with IEC/EN 60204-1. The voltage supply to machines
must be 20 ms of tolerance against instantaneous power failures as specified in
IEC/EN 60204-1.
The following shows representative configuration examples to conform to the IEC/EN/UL/CSA standards.
