For the power supply, isolated power is required. The manufacturer supplies an appropriate power supply as
accessory, see section 12.1.6
Power Supply DIN Rail (E-SYSPS)
, page 90. Beware of use of other power supplies,
which may not provide the necessary isolation and could cause instrument malfunction or damage!
