Installation of the air line
A 3 m air tube (2.6×4.0 mm) is included with each Encapsulator to connect it to external compressed
air or nitrogen.
1. Stick the air tube into the air inlet plug.
2. Attach the other side of the air tube to the external gas supply.
3. Deliver gas to the Encapsulator at 1.5 to 2 bar (23 to 30 psi) when running the instrument.
NOTE
The integrated pneumatic system (valve and fittings) will tolerate up to 7 bar (100 psi) at the inlet. An
over pressure safety valve, which opens at 1.5 bar, is incorporated after the pressure regulating valve, so
that the maximum air pressure at the air outlet is 1.5 bar. However the working range is from 0 to 1 bar.
5 .3 Electrical connections
Verify that the electrical requirement of the unit, stated on the type plate of the control unit, corre-
sponds to voltage of your local electrical network. Connect the power plug of the Encapsulator to the
mains supply.
!
Caution
Risk of instrument damage by wrong mains supply.
• External mains supply must meet the voltage given on the type plate.
• Check for sufficient grounding.
• Additional electrical safety measures such as residual current breakers may be necessary to
meet local laws and regulations! External connections and extension lines must be provided
with an earthed conductor lead (3-pole couplings, cord or plug equipment). All used power
cords shall be equipped with molded plugs only to avoid risks due to unobservant defective
wiring.
