Installation
3.7 Supply power to the analyzer
DANGER
Only connect the PHOSPHAX 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 power sockets on controllers as general
mains sockets. They are only designed to provide power for
the analyzers.
Important Note: Unless the sc1000 that connects to the
PHOSPHAX 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
PHOSPHAX 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
does not work with 24 V versions of the sc1000 because it does not
provide the appropriate connectors for the analyzers.
Refer to the sc1000 manual for more information on
connecting power.
1. Remove the power socket from the sc controller.
2. Connect the plug from the PHOSPHAX sc to the power socket
on the sc controller.
