9.3.3 Operation

After the "Mains, disconnect" command is executed, the Mains stays disconnected, and the IMD is
using the safe energy. The IMD will not reconnect the mains automatically unless a safety run is
performed, and the DC-link voltage is below DC-link Vlow.
Sending "0" to the special commands register (reg. 0x03) will not reconnect the AC mains supply to
the DC-link.

9.3.4 Deactivation

NOTE The Mains must be in OK state to be able to reconnect the Mains.
IMD Manager: select "13:Mains, connect" in the "States and special commands" in the "Monitor and
control" tab.
The indication in the "Power source" group in the "Monitor" tab will change to show that the Mains is
the energy source of the DC-link (will also change if the command is executed through
CAN/CANopen):
CAN/CANopen: send "13" to the special commands register (reg. 0x03). The IMD reconnects the AC
mains to the DC-link. The flag "Mains, disconnect" changes from 1 to 0.
