1.4 Safety details to be aware of when working on the

These service instructions apply only for the MGE-F

Remote and PC Tool E-products). If the application
includes other Grundfos products or systems, refer to
the service instructions of those products.
WARNING
Electric shock
Death or serious personal injury
- Before starting any work on the product, make
sure that the power supply is switched off and that
it cannot be accidentally switched on.
- Wait 30 minutes before doing any work inside the
product.
- Make sure that the mains cover is fitted in MGE-F
if you perform service work where fault finding with
power on and/or with connection to PC Tool Link is
needed. Turn off power and wait for the control box
to be de-energised before you check whether the
mains cover is fitted. If the mains cover is missing,
you can order it by part number 99926860.
- Installation, commissioning, service, and
maintenance of equipment, systems, and circuits
may only be performed by Grundfos service
technicians or a Grundfos Authorised Service
Partner (ASP) who have attended training
equivalent to Grundfos Electronics Service Expert
(GESE) or similar.
- Always observe local applicable safety regulation.
WARNING
Electric shock
Death or serious personal injury
- Due to the capacitors of MGE-F, touching live
electrical parts may be fatal, even after the mains
supply has been disconnected. Disconnect the
mains supply, and wait at least 30 minutes or the
amount of time stated on the warning label under
the terminal box cover before touching any live
parts.
- Note that the relay may be connected to an
external power supply and still be live after the
mains supply to the motor has been disconnected.
