by means of four screws—two per side (not included in the kit).
3.6 Preparation for Operation
After setting the Line Driver’s internal switches, as described in
Sections 3.4

ROUNDING
For your protection, the Line Driver must always be grounded. Any interruption
of the protective (grounding) conductor (inside or outside the instrument) or
disconnecting the protective earth can make this instrument dangerous.
Intentional interruption is prohibited.

ONNECTION
Power should be supplied to the Line Driver through the standard power cable
terminated by a standard 3-prong plug. Connect the cable between the mains
connector on the Line Driver rear panel and a standard grounded mains outlet.
WARNING
The protective earth terminals of this instrument must be connected to
the protective conductor of the (mains) power cord. The mains plug
must only be inserted in a socket outlet provided with a protective earth
contact. The protective action must not be negated by use of an
extension cord (power cable) without a protective (grounding)
conductor.
Make sure that only fuses with the required rated current are used for
replacement. The use of repaired fuses and the short-circuiting of fuse holders
must be avoided.
Whenever it is likely that the protection offered by fuses has been impaired,
the instrument must be made inoperative and secured against any unintended
operation.
