Power Connections - Mains Powered
Instruments
Mains powered instruments operate from a 100 to
240V (±10%) 50/60Hz supply. Power consumption is
7.5VA. Connect the line voltage (live and neutral) as il-
lustrated via a two-pole isolating switch (preferably
located near the equipment) and a 1amp anti-surge
fuse. If the instrument has relay outputs with contacts
carrying mains voltage, it is recommended that the re-
lay contacts supply should be switched and fused in a
similar manner, but should be separate from the instru-
ments mains supply.
