WFM 601i Serial Component Monitor
Rear Panel Connectors
The following is an overview of rear-panel connectors.
Figure 2-2 shows the WFM 601i rear panel.
This instrument is intended to operate from a single-phase power source with
one current-carrying conductor at or near earth-ground (the neutral conductor).
Only the line conductor is fused for over-current protection. Mains frequency is
50 or 60 Hz. Operating voltage range is continuous from 90 to 250 Vac.
WARNING. Do not connect power to the WFM 601i if it is not enclosed in a
prescribed cabinet. Dangerous potentials are present on the Power circuit board.
