3. Starting up the unit for operation
The Modbus connectors must not be connected or removed while the
units are powered up. Both Modbus units must be switched off before
making changes, otherwise the units may be damaged.
During commissioning, it may be necessary to work with the control
system boxes open. Components in these boxes must only be
touched with electrically-insulated tools.
Before doing any work on motor controls or motor cables and termi-
nal boxes, the power supply must be switched off for at least five mi-
nutes to allow the capacitors to discharge.
Before commission-
ing begins
● Check that the supply voltage is connected
● Set the HMI panel to specialist mode. See section 2.2
