Once activated, power will be switched off and the pump will be put in a safe condition.
To unlock these breakers, you must:
delete the origin of the defect, then,
switch power off (main switch
to
O
position),
open the electrical box,
unlock the circuit breakers and,
WARNING
Leak-tightness of the equipment
It is the user's responsibility to ensure this level of leak tightness is maintained, espe-
cially when dangerous gases are pumped. The operator must maintain this level of tight-
ness, particularly when pumping dangerous gases. Proceed as follows:
Perform a leak test on the entire pumping line after installation.
Carry out regular checks to ensure that there are no traces of the gases pumped in
the surrounding environment and that no air is entering the pumping line while the
pump is running.
WARNING
Electric shock hazard
Voltage and current can cause electric shock. Only skilled, authorized operator trained
in the relevant health and safety aspects (EMC, electrical hazards, chemical pollution,
etc.) may carry out maintenance work.
Isolate and lock out power line to the product by positioning the main switch on
O
.
Disconnect the power line cable from all power sources before doing any work on the
product and/or removing the covers.
WARNING
Risk of electromagnetic disturbance
The product’s EMC behavior is guaranteed only if the relevant EMC standards are fol-
lowed during installation.
Use shielded cables and connections for the interfaces in interference-prone environ-
ments.
WARNING
Hazards associated with non-compliant electrical installation
Safe operation after installation is the operator’s responsibility.
Connect the product to an installation that is compliant with local safety standards.
Do no carry out any alterations or modifications to the product on your own initiative.
Check that the pump is correctly connected to the emergency stop system for the
equipment (or pumping installation).
For specific questions, contact your service centers.
NOTICE
Safety interlock
The pump motors are protected against overload through solid state circuit breakers.
Never overridde these interlocks during installation, use or maintenance.
