4.9 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 illustrated 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 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

4.10 Power Connections - 24/48V AC/DC Powered Instruments

24/48V AD/DC powered instruments will operate from a 20 to 48V AC or 22 to 55V DC supply. AC

power consumption is 7.5VA max, DC power consumption is 5 watts max. Connection should be via

a two-pole isolating switch (preferably located near the equipment) and a 315mA slow-blow (anti-

surge type T) fuse.
