Wilo Yonos GIGA2.0-I Einbau- Und Betriebsanleitung Seite 141

Installation and operating instructions • Wilo-Yonos GIGA2.0-I/-D • Ed.01/2023-03
DANGER
Risk of fatal injury due to contact voltage!
Touching live parts will result in serious injuries or death!
Even when it is disconnected, high contact voltages can still occur in the
electronic module due to non-discharged capacitors. Therefore, work on
the electronic module must not be started until 5 minutes have elapsed!
• Disconnect all poles of the supply voltage and secure against recon-
nection!
• Check whether all connections (including potential-free contacts) are
voltage-free!
• Never insert objects (e.g. nail, screwdriver, wire) into openings on the
electronic module!
• Reinstall removed safety devices (such as module covers)!
DANGER
Risk of fatal electrical shock! Generator or turbine operation
during pump flow!
Even without the electronic module (without electrical connection),
there may be dangerous contact voltage at the motor contacts!
• Check for absence of voltage and cover or cordon off adjacent live
parts!
• Close the shut-off devices upstream and downstream of the pump!
DANGER
Risk of fatal electrical shock!
Water on the upper part of the electronic module can enter the elec-
tronic module when it is opened.
• Before opening, remove water, e.g. on the display, by wiping it off
completely. Avoid water penetration in general!
DANGER
Potentially fatal injury due to electronic module not being in-
stalled!
A life-threatening voltage may be present at the motor contacts!
Normal operation of the pump is only permitted with the electronic
module installed.
• Never connect or operate the pump without the electronic module
mounted!
CAUTION
Material damage due to improper electrical connection!
An inadequate mains design can lead to system failures and
cable fires due to mains overload!
• When designing the mains supply with regard to the used cable cross-
sections and fuses, pay special attention to the fact that, in multi-
pump operation, it is possible that all pumps operate at the same time
for short periods.
