Site Requirements
A suitable environment is important to ensure optimal performance of the
instrument.
Power Considerations
The module power supply has wide ranging capability. It accepts any line
voltage in the range described in Table 13 on page 37. Consequently there is
no voltage selector in the rear of the module. There are also no externally
accessible fuses, because automatic electronic fuses are implemented in the
power supply.
WARNING
Hazard of electrical shock or damage of your instrumentation
can result, if the devices are connected to a line voltage higher than specified.
➔ Connect your instrument to the specified line voltage only.
WARNING
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. electrical shock, when
the cover is opened and the module is connected to power.
➔ Always unplug the power cable before opening the cover.
➔ Do not connect the power cable to the instrument while the covers are removed.
CAUTION
Unaccessable power plug.
In case of emergency it must be possible to disconnect the instrument from the power
line at any time.
➔ Make sure the power connector of the instrument can be easily reached and
unplugged.
➔ Provide sufficient space behind the power socket of the instrument to unplug the
cable.
