work.
DANGER
Electric shock!
There is a risk of fatal injury from electric shock when working on electrical devices.
▪ Work on electrical components may only be carried out by qualified electricians!
▪ Switch off the voltage on all-poles of the pump and secure against unauthorised re-
start!
▪ 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!
▪ Do not operate the pump if the control module/Wilo-Connector is damaged!
▪ 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!
WARNING
Risk of burns!
Depending on the operating status of the pump and system (temperature of the
fluid), the entire pump can get hot.
▪ Risk of burns upon coming into contact with the pump!
▪ Allow the system and pump to cool to room temperature!
Follow all safety instructions described in sections "Safety information [} 116]" to
"Electrical connection [} 135]"!
Install and connect the pump as described in section "Installation [} 127]" and "Elec-
trical connection [} 135]" after having completed maintenance and repairs. Switch on
the pump as described in section "Put into operation [} 147]".
Before dismantling/installation, make sure that the "Shutdown" section is taken
into consideration!
