At the rear of the multi EA 4000 are the mains switch, the gas inlets for the oxygen
and argon supply, the connections for the connection to the C/S or Cl module and the
mains connection cable.
Using the mains switch the multi EA 4000 can be completely disconnected from the
mains, which is important for maintenance and repair.
If the mains switch is switched on, the analyzer is in standby mode. For daily operation
the multi EA 4000 is switched on and off from the On/Off switch at the front (1 in Fig-
ure 7). The analyzer is then still e.g. ventilated when switched off. During extended in-
terruptions of measurements lasting several days, the multi EA 4000 must be discon-
nected from the mains using the mains switch.
NOTICE
! During operation both switches must be on.
