Power & Standard Outputs Connection Details
CAUTION!
Always remove the main power from the system
before any alterations to the wiring. Ensure that
both power lines are isolated. Make sure that the
power cannot be switched on by accident whilst the
instrument is being connected. For safety reasons
an earth connection must be made to the earth
terminal of this instrument.
Local wiring and safety regulations should be strictly
adhered to when installing this instrument. If the
installation methods and cable types recommended
in this guide are followed, then the instrument will
achieve the levels of EMC protection as specified in
the appropriate manual.
Consult the serial label on the side of the
instrument for supply voltage requirements.
