(See Section 2. Important Notes concerning wiring).
Electrical connections are made through the metric cable gland openings prepared
underneath the instrument. Not all openings may be free. The electrical connections are
located inside the computer housing.
The Units must be connected to the mains supply via a suitable rated and approved fused
isolator unless such fusing / isolation is provided by associated equipment. When fitted,
the isolator should be close, readily accessible and marked as to function.
Close the terminal cover completely after electrical installation. Water and humidity
inside the instrument may result in corrosion and malfunction.
i
If the instrument is operated at high voltages, additional care has to be taken to provide
reliable ground connections. Ground (PE) must be connected direct to the PE terminal or,
if this is not sufficient according local rules, to the computer housing (PE bolt inside, right
side).
