Electrical connection
CAUTION
Electrical defect!
Condensate that accumulates in the motor can cause an electrical defect.
▪ Insulate pump housing only up to the separating gap to the motor!
▪ Keep the condensate drain grooves unobstructed to ensure that condensate that de-
velops in the motor can drain off without problems!
Fig. 20: Insulate, leave condensation drain free
1. Check impermeability of the pipe/flange connection.
Electrical connection may only be carried out by a qualified electrician and in accord-
ance with the applicable regulations!
The "Safety information [} 116]" section must be strictly observed!
DANGER
Risk of fatal electrical shock!
• Immediate risk of fatal injury if live components are touched!
• In particular, persons with medical aids, such as cardiac pacemakers, insulin pumps,
hearing aids, implants or similar are at risk.
Death, severe injury and damage to property may be the result.
A professional medical assessment is always necessary for such persons!
• Failure to install safety devices (e.g. module cover of control module) can cause
electrical shock, potentially resulting in life-threatening injuries!
• If setting and operating elements are improperly removed from the control module,
there is a danger of electric shock if interior electrical components are touched!
• 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.
Risk of fatal injury!
▪ Reinstall all removed safety devices such as module covers!
▪ Only connect or operate the pump with the control module installed!
▪ Do not operate the pump if the control module/Wilo-Connector is damaged!
▪ Disconnect all poles of the supply voltage and secure against reconnection!
Work on the control module may only be started after 5 minutes have elapsed, due to
the dangerous residual contact voltage!
▪ Check whether all connections (including potential-free contacts) are voltage-free!
