Connection of main power supply
The connection of the main power supply needs a remote power supply box. The shut-
off box must be installed in an area where there is no possibility of an explosive
atmosphere.
Remote Power Supply Box
The shut off box is necessary to power up and down the analyzer in a safe area. It
prevent that a brake away spark is generated in the industrial area. The shut off box
belongs to the safety concept of the analyser.
The Remote Power Supply Box as optionally supplied by MRU, has a switch-off
contactor
(K1)
, with 3 make contacts (normally open). The power contactor K1 is
activated after the analyser is powered on by pushing the power-on button until the
green LED is light-on. In case of an alarm, the power contactor K1 is deenergized. The
circuit diagram shows the correct wiring of the power contactor installed in the
remote power supply box.
The circuit diagram of above pictured device must be implemented by user as part of
the safety concept.
