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 2 on page 25. 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
The 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.
