•
Switch off the voltage on all-poles of the pump and secure against unauthorised restart!
•
Always deactivate the power supply from the pump and if necessary SSM and SBM!
•
Due to the presence of dangerous contact voltage, work on the module must not be started until
5 minutes have elapsed!
•
Check whether all connections (even potential-free contacts) are voltage-free!
•
The pump may still be live even in voltage-free state. The rotor induces a contact voltage, which is also
present at the motor contacts. Close the existing shut-off devices in front of and behind the pump!
•
If the control module/cable is damaged, do not operate the pump!
•
In case of impermissible removal of operating and settings elements on the control module, there is a risk
of electrical shock if inner electrical components are touched!
9.3
Dismantling/installation
Before any dismantling/installation operation, make sure that the "Shutdown" section has been taken
into consideration!
WARNING
Risk of burns!
Incorrect dismantling/installation can result in personal injury and material damage.
Depending on the operating status of the pump and the system (fluid temperature), the en-
tire pump can get very hot.
There is a severe risk of burns from simply touching the pump!
•
Allow the system and pump to cool to room temperature!
WARNING
Risk of scalding!
The fluid is under high pressure and can be very hot.
There is a risk of scalding due to escaping hot fluid!
•
Close shut-off devices on both sides of the pump!
•
Allow the system and pump to cool to room temperature!
•
Drain the shut-off branch of the system!
•
If no shut-off devices are fitted, drain the system!
•
Follow the manufacturer's instructions and safety data sheets for possible additives in the system!
WARNING
Danger of injury!
Danger of injury caused by falling motor/pump after loosening the fastening screws.
•
Comply with national regulations for accident prevention and also with the operator's internal work, com-
pany and safety regulations. If necessary, wear protective clothing and equipment!
