Power Connection
Make sure the vacuum connection is properly made.
DANGER
The gauge may only be connected to power supplies, instru-
ments or control devices that conform to the requirements of a
grounded protective extra-low voltage (PELV) and limited power
source (LPS), Class2.
· The connection to the gauge has to be fused

.
Ground loops, differences of potential, or EMC prob-
lems may affect the measurement signal. For optimum
signal quality, please do observe the following notes:
· Use an overall metal braided shielded cable. The
connector must have a metal case.
· Connect the cable shield to ground at one side via
the connector case. Make sure the connector case
has direct contact to the cable's shield on its whole
circumference. Do not connect the other side of the
shield.
· Connect the supply common with protective ground
directly at the power.
· Use differential measurement input (signal common
and supply common conducted separately).
· Potential difference between supply common and
housing ≤18V (overvoltage protection).
6)
INFICON controllers fulfill these requirements.
