2.Pre-Measurement Procedures - 2.1.Before Switching On the Power
1WMPD4004444

WARNING
Module installation/removal and replacement must be performed after disconnecting all the cables
connected to the module, turning off the power switch of the main unit, and disconnecting the power
cable.
Insert the module along the guide rails, and securely fix the two knurled screws with a Phillips head
screwdriver. Incomplete module installation may lead to failure.
Module disassembly is extremely dangerous. It must not be performed other than by our service
engineers, as it may also lead to failure and prevent performance from being guaranteed.
Make sure to install an empty panel on slots where no module is installed. Failure to do so may lead
to failure due to the intrusion of foreign material or dust. (Empty panels are shipped together with
the RA series main unit.)
When storing the module, place it inside an anti-static bag and packaging box like those it was
shipped with, as static electricity may lead to failure. This product can be stored in the range of -20
to 60°C and 20 to 85% RH (without condensation).
The measurement category of this module is category II (CAT II) (300 V). The module cannot be
used with measurement categories that exceed its specifications, such as CAT III and CAT II
(600 V).
Connect the input signal to the module after connecting the power cable of the RA series main unit
where the module is installed to a 3-pole AC outlet, grounding it, and then turning on the power of
the main unit.
High voltage may already be applied as the input signal. Set the measurement range of the module
to the maximum and connect the input cable to the module before connecting to the signal source.
Take care to not directly touch the conductors when connecting to the signal source, in order to
prevent electrocution.
A dedicated input cable for each module is provided to meet the specifications such as the
measurement category and insulation withstand voltage. Use the dedicated input cable for the type
of measurement.
CAUTION
When transporting the product and modules, use the package and packaging material supplied at
factory shipment, or use a package and packaging material more shock-resistant than those
supplied.
We recommend a periodical calibration to maintain the accuracy of the input units. More reliable
measurements are possible by calibrating the input units once a year (extra cost option).
