DANGER
DANGER: overpressure in the vacuum system
>1 bar
Injury caused by released parts and harm
caused by escaping process gases can result if
clamps are opened while the vacuum system is
pressurized.
Do not open any clamps while the vacuum sys-
tem is pressurized. Use the type of clamps which
are suited to overpressure.
DANGER
DANGER: overpressure in the vacuum system
>2.5 bar
KF connections with elastomer seals (e.g.
O-rings) cannot withstand such pressures. Pro-
cess media can thus leak and possibly damage
your health.
Use O-rings provided with an outer centering
ring.
DANGER
DANGER: protective ground
Incorrectly grounded products can be extremely
hazardous in the event of a fault.
The gauge must be electrically connected to the
grounded vacuum chamber. This connection
must conform to the requirements of a protective
connection according to EN 61010:
• VCR
® connections fulfill this requirement.
• For gauges with a KF connection, use a con-
ductive metallic clamping ring.
Caution

propriate measures to ensure cleanliness and
prevent damages.
