Fundamental settings for normal operation
For normal operation the following connections must be carried out on the analogue interface:
Pin 3 - Pin 4,
Pin 5 - Pin 6,
Pin 10 - Pin 11
These connections are already made at the included Sub-D plug.
Output terminals on the rear side
HI (HV socket) + or – output on the central contact, depending on
polarity (standard is +). The screen is connected to the
safety ground PE and may never be connected to the load.
LO (black) – output
(yellow) PE safety earth, return path for the load
Interfaces (according to setup)
24-pole socket IEEE bus interface (if equipped)
9-pole Sub-D connector RS-232 interface (if equipped)
15-pole Sub-D connector Analogue interface (must always be plugged)
RJ45 connector Ethernet port (if equipped)
