Open Cover (Safety)
Do not remove instrument covers when operating. Before the instrument is
switched ON, all protective earth terminals, extension cords,
auto-transformers, and devices connected to it must be connected to a
protective earth via a ground socket. Any interruption of the protective earth
grounding will cause a potential shock hazard that could result in serious
personal injury. Whenever it is likely that the protection has been impaired,
the instrument must be made inoperative and be secured against any intended
operation.
Open main cover
The following procedures require opening the main cover of the instrument.
➔ Always ensure the instrument is disconnected from the line power when the main
cover is removed.
➔ The security lever at the power input socket prevents that the instrument cover is
taken off when line power is still connected.
Module is partially energized when switched off, as long as the power cord is
plugged in.
Repair work at the module can lead to personal injuries, e.g. shock hazard, when the
cover is opened and the module is connected to power.
➔ Make sure that it is always possible to access the power plug.
➔ Remove the power cable from the instrument before opening the cover.
