Powering the Instrument
THERE ARE 2 SUPPLY VARIANTS: a mains supply variant and a low
voltage supply variant. The instrument is designed to operate from either
an AC supply with voltages in the range 90 to 230V AC 50/60Hz mains
supply or from a DC supply with voltages in the range 24 to 32V DC (20
to 30V AC) 50/60Hz low voltage supply with a maximum power
consumption of 20VA when all outputs are fully loaded and the display
has all segments illuminated.
The diagrams below show how the instrument should be connected to the
mains supply. Isolation should be provided by a double pole switch and a
time delay 200mA fuse.
WARNING - The instrument is designed for installation in an
enclosure which provides adequate protection against electric shock.
Access to power terminals should be restricted to authorised skilled
personnel only. Application of supply voltages higher than those for
which the instrument is intended may compromise safety and cause
permanent damage.

Recommended Low Voltage Supply Connections
BEFORE POWERING UP THE INSTRUMENT,
check the model label on the underside of the
instrument for the supply variant, eg. MAINS OR
LOW VOLTAGE.
