Applying an incorrect voltage to SELV lines will result in incorrect voltage in all pumps and on-
site building automation devices that are connected to SELV lines.
• Before commencing work, switch off the power supply and secure it from being switched
on again.
– Due to the presence of dangerous contact voltage, work on the control module must
not be started until 5 minutes have elapsed!
• Check whether all connections (including potential-free contacts) are voltage-free.
• Only connect or operate the pump with the control module installed.
• Never open the control module and never remove configuration and operating elements.
• Never put the pump into operation if the control module/Wilo plug is damaged.
