DANGER
Risk of fatal electrical shock!
• Immediate risk of fatal injury if live components are

ing injuries!
• Even if the Wilo-Connect module Yonos MAXO run
signal light is not illuminated, voltage may be
present!
• If setting and operating elements are improperly re-
moved from the Wilo-Connect module Yonos MAXO,
there is a danger of electric shock if interior electrical
components are touched!
• Applying an incorrect voltage to interfaces will re-
sult in incorrect voltage in all pumps and on-site
building automation devices that are connected to
the interface.
ƒ
Before all work, deactivate the power supply (if necessary, SSM,
SBM and twin-head pump management) and safeguard against
accidental switch-on!

Never operate the Wilo-Connect module Yonos MAXO without
the module cover closed!
