Warning
Never make any connections in the pump control box unless

have been switched off as well.
Caution
Always use an antistatic service kit (Grundfos ESD,
protection set prod. no. 96884939) when dismantling and
assembling the terminal box as the electronics are sensitive
to static electricity. Connect the antistatic service kit to the
connection terminal of the protective earth lead (PE terminal).

The arrows marked on the side of the fan shows the direction
of rotation and the direction of the cooling air. See fig. 20.
