Electrical installation
The RM4 Meter is designed for continuous operation and no power switch is fitted to the unit. It
is recommended that an external switch and fuse be provided to allow the unit to be removed for
servicing. The terminal blocks allow for wires of up to 2.5mm
2
to be fitted for power supply and
relays 1 and 2 or 1.5mm
2
for input connections and optional outputs. Connect the wires to the
appropriate terminals as indicated below.
Refer to connection diagrams provided in this manual to confirm proper selection of voltage, polarity
and input type before applying power to the instrument. When power is applied the instrument
will cycle through a display sequence, indicating the software version and other status information,
this indicates that the instrument is functioning. Acknowledgement of correct operation may be
obtained by applying an appropriate input to the instrument and observing the resultant reading.
Note that the power supply type is factory configured. Check power supply type before connecting.
Relay outputs are voltage free contacts.
