Verify the mains voltage at site of installation corresponds to the analyzer´s
rated voltage as given on the nameplate label!
Verify the safety instruction given by power supply unit manufacturer !
The mains socket has to be nearby the power supply unit and easily
accessible! Disconnecting from mains requires unplugging the power plug!
To comply with the CE mark requirements use only power supply units of
type UPS 01 T, DP 157, SL5, SL10 (DP 157 for rack installation only) or
equivalent units. Equivalent units must provide SELV output voltages!
Verify proper polarity when connecting DC 24 V operated analyzers !
These instruments provide a protective earth terminal. To prevent electrical
shock hazards the instrument must be connected to a protective earth.
Therefore the instrument has to be connected to mains by using a three
wire mains cable with earth conductor!
Any interruption of the earth connector inside or outside the instrument or
disconnecting the earth terminal may cause potential electrical shock
hazzard! Intended interruption of protective earth connections is not
permitted!
ELECTRICAL SHOCK HAZARD !
For analyzer module (A) [external installation or platform mounting] it is not allowed to
