SIMOVERT MASTERDRIVES
The unit has hazardous voltage levels up to 5 minutes after it has been
powered down due to the DC link capacitors. The unit must not be
opened until at least after this delay time.
The optional boards contain components which could be damaged by
electrostatic discharge. These components can be very easily
destroyed if not handled with caution. You must observe the ESD
cautionary measures when handling these boards.
Disconnect the unit from the incoming power supply (AC or DC supply)
and de-energize the unit. Remove the 24 V voltage supply for the
electronics.
Open the front panel.
Remove the CU board or the adaption board from the electronics box
as follows:
♦ Disconnect the connecting cables to the CU board or to the optional
boards.
♦ Undo the two fixing screws on the handles above and below the CU
board or the adaption board.
♦ Pull the CU board or the adaption board out of the electronics box
using the handles.
♦ Place the CU board or the adaption board on a grounded working
surface.
Insert the optional board from the right onto the 64-pole system
connector on the CU board or on the adaption board. The view shows
the installed state.
Screw the optional board tight at the fixing points in the front section of
the optional board using the two screws attached.
Re-install the CU board or the adaption board in the electronics box as
follows:
♦ Insert the CU board into mounting position 1 and the adaption board
into mounting position 2 or 3.
Mounting position 3 cannot be used until at least one adaption board
has been installed at mounting position 2. Boards should first be
installed in mounting position 2, before mounting position 3 is used.
♦ Secure the CU board/adaption board at the handles with the fixing
screws.
Re-connect the previously removed connections.
Check that all the connecting cables and the shield sit properly and are
in the correct position.
