Furman PST-2+6 Mode D'emploi page 7

Ground Indicator:
A proper safety ground is necessary for correct operation and
protection of connected equipment as well as user safety. The green
"Ground" LED is on when the PST-2+6 is plugged into a properly
grounded wall outlet. If the wall outlet is not properly grounded, the
green "Ground" LED will not light. If this is the case, it is advisable to
find a properly grounded wall outlet or consult a licensed electrician
to make the necessary modifications to insure proper grounding as
the wall outlet.
Mounting
If the Power Station needs to be mounted to the inside panel of a rack
or hung from a wall, a convenient crossed oval cutout is provided on
the unit's bottom panel. A standard No. 6 pan head screw can be
used in the same way a picture is hung from a wall. Simply measure
the centers on the bottom of your Power Station. This will be the
distance from the two mounting holes drilled into your wall, rack or
cabinet surface. Once the screw is fastened flush with the surface,
back it out approximately 1/4". The screw head should push through
the crossed cutout on the bottom surface of the Power Station. Next,
simply allow the Power Station to move down and seat into the end
of its oval cut-out. Adjust the pan head screw if necessary.
