Installation
3.8 Supply power to the analyzer
DANGER
Only connect the AMTAX sc to the sc1000 power supply
when the instrument is completely wired internally and it is
correctly earthed.
DANGER
Always connect a ground fault interrupt circuit (GFIC) or a
residual current circuit breaker (trigger current maximum at
30 mA) between the main power supply and the sc1000.
DANGER
Do not use the controller power sockets as general
mains sockets. They are only designed to provide power
for the analyzers.
Important Note: The power plug serves in addition to the power
supply to isolate the device quickly from the mains where
necessary.
Therefore make sure that socket to which the device is connected
is easy to reach by each user at all times.
Important Note: Unless the sc1000 that connects to the AMTAX sc
analyzer is already fitted with ac mains overvoltage (surge)
protection device, surge protection must be provided between the
mains connection of the sc1000 and the AMTAX sc analyzer if it is
demanded by the local regulation.
Only supply power to the instrument after all plumbing connections,
reagent installations and system start-up procedures have been
completed.
sc1000 power sockets can only be connected if a wide range
115/230 V power supply is built into the sc1000 controller. This
