If the device is transported from a cold to a warm environment condensation
may result in device function failure. In this case you have to wait until the
temperature of the device has adapted to the ambient temperature, before
switching it on.
If it is assumed that the device can not be operated safely any more, it must be
put out of operation and secured against further usage. Operator‘s safety may
be compromised by the device when, for example:
• it has visible damage,
• it is not working as specified,
• it has been stored under unsuitable conditions for a longer time.
In cases of doubt, the device should always be returned to the manufacturer for
repair or maintenance.
Connection to other devices
Conceive the wiring most thoroughly when connecting to other
devices. Under certain circumstances, internal connections in third
party devices (e.g. connection GND to earth) may result in not-per-
missible voltages that may affect the device itself or a connected
device in its function or even destroy it.
External power supply
The unit can be powered by an external power supply. Whenever
you connect an external power supply, ensure that the operating
voltage indicated on the power supply matches the mains supply
voltage available at the place of operation and that the AC outlet
is protected by a residual current circuit breaker. Failure to do so can result in
damage to the device and injure the user.
Warning: When operating the device with a defective power supply (e.g. short
circuit from mains voltage to output voltage), life-endangering voltages may
be present on the device (for example, at the output terminals)!
Unplug the external power supply from the mains before electrical storms oc-
cur and when it is unused for long periods of time to reduce the risk of electric
shock or fire.
