Power Connections
Power Connections - Mains Powered Instruments
Mains powered instruments operate from a 100 to 240V (±10%) 50/60Hz supply. Power
consumption is 20VA. Connect the line voltage (live and neutral) as illustrated via a two-pole
IEC60947-1 & IEC60947-3 compliant isolation switch / circuit breaker and a UL listed fuse
type: 250V AC 1Amp anti-surge. If the instrument has relay outputs with contacts carrying
mains voltage, it is recommended that the relay contacts supply should be switched and
fused in a similar manner, but should be separate from the instruments mains supply.

WARNING:
CHECK THE INFORMATION LABEL ON THE CASE TO DETERMINE THE CORRECT
VOLTAGE BEFORE CONNECTING TO A LIVE SUPPLY.
CAUTION:
This equipment is designed for installation in an enclosure that provides adequate
protection against electric shock. The isolation switch should be located in close
proximity to the unit, in easy reach of the operator and appropriately marked.
