5.3 Establishing the electrical 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.
To operate the gauge with a Pfeiffer Vacuum total pressure measuring and control unit, you will require
a corresponding measurement cable from the ActiveLine Accessories. Otherwise, you can also manu-
facture a measurement cable specifically for this purpose.
