Vacuum connection
Mounting orientation
The installation position can be freely selected. The preferred position is a horizontal to
vertical position so that condensate and particles do not penetrate the measurement
chamber.
To facilitate adjustment after the transmitter has been installed, a free space of about
40 mm in axial direction should be assured in front of the "ATM" and "HV" push buttons.
Connecting the trans-
mitter
CAUTION
Vacuum component!
Dirt and damage impair the function of the vacuum component.
When handling vacuum components, ensure that they are kept clean and are protec-
ted against damage.
Ensure that the connection flange is clean, dry and free of grease.
CAUTION
Excess pressure in the vacuum system 1500 to 4000 hPa
Damage to health through emission of process media, because elastomer washers
cannot withstand the pressure.
Use sealing rings with an outer centering ring.
CAUTION
Missing protective grounding!
The transmitter must be electrically connected to the grounded vacuum chamber.
For gauges with a KF flange, use a conductive metallic clamping ring.
Carry out the flange connection according to the requirements of DIN EN 61010.
CAUTION
Excess pressure in the vacuum system > 1000 hPa
Danger of injuries by inadvertent opening of elements under stress due to parts flying
around.
Only use stressed elements, which can be opened and closed with appropriate tools
(e.g. strap retainer-tension ring).
