SAFETY
5. Prior to switching on the device, ensure that the nominal mains voltage set on the device
and the nominal mains voltage of the supply match. If it is necessary to change the voltage
setting, it may also be necessary to change the respective mains fuse for the device.
6. In case of devices in protection class I with a fl exible mains cable and mains plug, opera-
tion is only allowed using wall socket outlets with an earth contact and connected earth
conductor.
7. Any intentional interruption of the earth conductor, either in the supply cable or in the de-
vice itself is not allowed and can result in a dangerous voltage being laid directly on the
device. If extension cables or power strips are used, it is imperative that these are checked
that they comply with safety regulations at regular intervals.
8. The device is not equipped with a mains switch allowing mains disconnection. Therefore,
the plug on the connection cable is to be considered a mains power disconnection ele-
ment. It is to be ensured the mains plug is easily accessible at all times (length of the con-
necting cable approx. 2 m). Function switches or electronic switches are not suitable for
mains isolation. If devices without a mains switch are integrated into racks or systems, the
mains power disconnection element is to be moved to system level (system level switch-
off).
9. During all work, the local and national health and safety regulations are to be followed.
Prior to work on the device or opening the device, it is to be isolated from the mains sup-
ply. Calibration, replacement of parts, maintenance and repair should only be undertaken
by trained electricians. If safety-related parts (e.g. mains switches, mains transformers or
fuses) are replaced, these must only be replaced with original parts. A safety test is to be
performed after any replacement of safety-related parts (visual inspection, earth conductor
test, insulation resistance, leakage current measurement, function test).
10. In case of connections to information technology devices, it is to be ensured that these
devices comply with IEC950/EN60950.
11. Lithium batteries are not to be subjected to high temperatures or fi re. Keep the batteries
away from children. If the battery is incorrectly replaced, there is a risk of explosion. Re-
place the batteries only with the original type (see list of spare parts). Lithium batteries are
hazardous waste. Only dispose of them in containers provided for this purpose. Do not
short-circuit batteries.
12. Devices that are returned or sent in for repair must be packed in the original packaging
or in packaging that provides protection against electrostatic charging and discharging as
well as against mechanical damage.
13. Discharges via connectors can damage the device. The device is to be protected against
electrostatic discharge in use and operation.
14. Clean the exterior of the device with a soft, fl uff-free duster. Under no circumstances use
solvents such as thinners, acetone or similar, as otherwise the front panel markings or
plastic parts may be damaged.
15. Additional safety instructions in this manual are also to be followed.
