z Input/output ground
The signal ground of FUNCTION OUT and SYNC OUT is floated from the chassis and the input/output
ground of these signals is common.
Signal ground dielectric strength: 42 Vpeak, 30 Vrms (DC to 20 kHz continuous)
The input/output ground of all other signals is connected to the chassis.
