Installation of the AGPS board
WARNING! Dangerous voltages can be present on the AGPS board even when the
115...230 V AC supply is switched off. Follow the Safety instructions on the first
pages of this manual and the instruction in this chapter when working on the AGPS
board.
Make sure that the drive is disconnected from the mains (input power) and the
115...230 V AC source for the AGPS board is switched off during installation
and maintenance. If the drive is already connected to the mains, wait for 5 min
after disconnecting mains power.
WARNING! The supply voltage for the AGPS board is 230 V AC. If the board is
supplied with 24 V DC, the board is damaged and it needs to be replaced.
