contrAA 600
Optimum device function strongly depends on a correct mains connection with adequate
cable cross-section. The mains connection shall be protected on the input (building) side
with a 35 A slow-blow fuse and must be installed prior to delivery of the contrAA 600 near
the assembly point. The instrument cable is 3 m long. The CEE surface socket
(2 pole + E blue 5UR 3 206-2 220/32, Siemens) is supplied according to the terms of deliv-
ery.
The mains plug is used to isolate the device from the power supply. Therefore make sure
that the mains plug is readily accessible.
All other components of the contrAA 600 (e.g., PC, printer etc.) are connected via the 5-way
socket strip supplied, which is plugged into the rear of the contrAA 600, and connected to the
same phase as the base device itself. When connecting your own PC printer configuration to
the 6-way adapter, observe the limit of the permitted line current (a total of 5 mA with auxilia-
ry devices). To avoid sudden voltage fluctuations, do not connect the contrAA 600 to the
same electrical circuit as other power-intensive devices.

Gas supply
CAUTION! LEAKING GAS LINES!
The operator must ensure that the connector type used on the outlet side of the gas pres-
sure controller is adequate for the national requirements that shall apply.
The operator must carry out the necessary safety leakage tests weekly on all gas supplies
all the way to the device. For this, possible pressure losses from closed systems and lines
under pressure are to be determined. The leak is to be localized and corrected immediately.
The required inert gas is used to protect the graphite components of the atomizer, which are
subjected to extreme temperatures. The inert gas is also used as a means of transport for
the pyrolysis components accrued during the analysis. The purity of the inert gas is extreme-
ly important for the analysis and for the lifetime of the graphite tube.
