12 Electrical and Signal Connections
All electrical work must be carried out by a competent person.
Power and signal cabling are the responsibility of the customer and should comply
with local regulations.
Cables should be selected of a conductor size and insulation suitable for the
purpose used.
The instrument and power leads should always be grounded/earthed.
Screened signal leads are recommended and a single ground termination made at
one end only.
