Care must be taken at mounting of the pipes connections to avoid any torsion of the
housing and damage of the instrument.
For separator discharge pipes, up to 75 mm OD a standard "T"-type junction of the welded
or screwed type is satisfactory for the tapping point. For the separator discharge pipes of
80 mm OD and above a sample probe should be employed which protrudes into the
discharge piping by approx. 25 % of the ID of the pipe.
If connection to a vertical section of the separator outlet piping is impractical, the tapping
may be made into the side of the horizontal pipe. Avoid top or bottom entry.
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 front cover completely after electrical installation. Water and humidity inside the
instrument may result in corrosion and malfunction.
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).
