Can it do harm to turn off Wii-U with orange light?

I have my Wii U connected with a power strip with a switch. That switch is always off, except when I want to play a game, obviously. When I stop playing, the Wii U is updating most of the time (orange light). Can I harm my console by hitting the switch and thus removing power? Or is it recommended to wait for the light to turn red?
For clarification, I mean this little light (not my picture):
