WARNING
Risk of injury due to electrical shock, as well as sparking and damage to
the flow meter, if an inappropriate connecting cable is used
▶ It is imperative that an original connecting cable and original glands from Rota
Yokogawa are used.
▶ Install cables tension-free.
WARNING
Risk of sparking and damage to the flow meter due to incorrect wiring
▶ Observe connection diagram for the connecting cable according to chapter Connec-
tion terminals of connecting cable.
WARNING
Risk of injury due to electrical shock, as well as damage to the flow meter
due to insufficient clamping of the connecting wires
▶ Completely open connection terminal by using the operating tool.
▶ Insert connecting wires with wire end ferrules into the corresponding connection ter-
minal up to the stop.
▶ Close connection terminal.
CAUTION
Don't install the connecting cable at ambient temperatures below -10 °C.
NOTICE
Wiring work must only be performed at max. 80 % humidity and temperatures up to
31°C, linearly decreasing to 50 % relative humidity at 40°C.
NOTICE
Although Rota Yokogawa considers the guidelines of EMC, please be aware that con-
ducted and radiated electromagnetic emission may effect the EMC of adjacent areas.
NOTICE
Be aware that improper earthing, false wiring and use of cable out of specification may
lead to instrument damage and/or disturbance of other sensitive electrical equipment due
to increased electromagnetic emissions/immunity.
NOTICE
Be aware that wrong input voltage may lead to disturbance of other sensitive electrical
equipment due to increased electromagnetic emissions.
▶ The applicable national standards must be considered for installation.
▶ Only sensors and transmitters with compatible model codes may be interconnected. If
these instructions are not observed, flawless function of the flow meter cannot be
guaranteed.
