Connector C4 – AC or DC Power
• Universal 90 – 250 V AC 50/60 Hz, or, 24 V DC version dependent on factory
set option.
Important Notes for Both AC and DC Powered Units
The power supply to the instrument must be protected by a 1A fuse.
A local isolation switch is advisable for ease of isolation during maintenance
to reduce the possibility of electric shock or damage to the instrument.
The power supply ground GND terminal must be wired to a suitable
permanent ground point.
For European CE compliance on AC wiring only, the supplied ferrite bead
must be installed on the power supply cable approximately 50 mm from the
connector using the tool supplied with the instrument.
The power supply wires are retained by screws and care should be taken
to ensure that the exposed section of the wire is fully inserted and that no
loose strands are exposed.
Cables should be properly supported and segregated.
