Space requirements
Make sure that the power plug on the power supply (wall socket or
power strip) is always accessible, so that the device can be disconnect-
ed from the power supply.
Ensure adequate ventilation around the device, otherwise it may over-
heat and malfunction:
-
Min. 5 cm distance if another device is set on one side.
-
Min. 10 cm distance if further devices are set on both sides.
-
At least 15 cm to the cooler fan on the rear.
The mounting of a small device to an AZURA L device with a mounting
bracket does not affect the performance of either device. The space
requirements specified in both device instructions do not apply in this
case.

Power supply
4.3.1
Power supply requirements
Failure-free power supply: For failure-free operation, the electrical
voltage must be free of fluctuations, residual currents, voltage peaks
and electromagnetic interference. The device must receive sufficient
voltage and reserve capacity.
Check voltage: Only connect devices to a power supply whose voltage
corresponds to the permissible voltage of the device.
Power consumption: The nominal power of the connected devices
must not exceed 50 % of the highest connected power capacity, since
higher currents can flow briefly when the device is switched on.
Main connection: The electrical power supply at the operation site
must be connected directly to the nearest main power connection.
Grounding: The connectors for the voltage must be grounded
accordingly.
4.3.2
Power supply cables and plugs
Original parts: For power supply, use the supplied power cable and
plug to meet the specifications which are described in the chapter
“11. Technical data” on page 62. Detachable power cable cables are
not allowed to be replaced with other cable types.
Country-specific plugs: Before switching on the device, check wheth-
er the supplied plug is approved for your country. Overview of the
device- and country-specific plug types from KNAUER:
Power strips: If several devices are connected to one power strip,
always consider the maximum power consumption of each device.
Access to power supply: Make sure that the power plug on the pow-
er supply (wall socket or power strip) is always accessible, so that the
device can be disconnected easily from the power supply.
Damaged power supply cables and plugs: For safety reasons, dam-
aged or faulty cables and plugs must not be used to connect the
device to the power supply. Replace defective cables and plugs only
with KNAUER accessories.
