Recommendations
► If possible, make sure that the gauge is not exposed to any vibrations during operation, as vibra-
tions will lead to deviations in the measured values.
► Mount the gauge in a horizontal to upright mounting orientation (flange facing downwards).
– This prevents condensate and particles from accumulating in the measurement chamber.
► Ensure that the buttons of the gauge can be easily accessed with the stylus once fitted.
► Fit a seal with centering ring and filter for applications with pollution and to protect the measure-
ment system against contamination.
Procedure
1. Remove the protective cap and store in a safe place.
2. Assemble the gauge with vacuum components from the
Pfeiffer Vacuum Components Shop
the vacuum system.
5.2 Establishing electric connection
DANGER
Danger to life due to dangerous contact voltage
Voltages above 30 V (AC) or 60 V (DC) are considered dangerous in accordance with EN 61010. If
you come into contact with dangerous contact voltage, this can result in injury through electric shocks
or even death.
► Only connect the product to devices which meet the following criteria:
● Requirements of the earthed protective extra-low voltage (PELV)
● Limited power source (LPS) Class 2
► Secure the line to the product.
– Pfeiffer Vacuum measuring and control equipment complies with this requirement.
NOTICE
Damage sustained as a result of improper connection
Improper connection, incorrect polarity or impermissible supply voltage will damage the gauge.
► Always connect the supply earth (Pin 5) with the earth for the supply unit.
► Always connect the shielding (Pin 6) with the earth for the supply unit.
Required tools
● Crosshead screwdriver
● Torque wrench (≤ 0.2 Nm)
