Safety (Continued)
• To prevent electrical shocks or damage to the
instrument, do not connect more than 30V between
the terminals, or between the terminals and the
ground (earth).
• UPM only. To prevent a dangerous release of
pressure, isolate and bleed the system before you
disconnect a pressure connection.
Before you start an operation or procedure in this
publication, make sure that you have the necessary skills
(if necessary, with qualifications from an approved
training establishment). Follow good engineering practice
at all times.
