4.2.3 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 disconnec-
ted 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.
4.3 Power supply
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.
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
“Technical Data” (see chapter 11 on page 30). Detachable power
cable cables are not allowed to be replaced with other cable types.
Country-specific plugs: Before switching on the device, check whether
the supplied plug is approved for your country. Overview of the de-
vice- and country-specific plug types from KNAUER:
www.knauer.net/plugs
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 power
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, dama-
ged 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.

13Installation and initial startup
4.4 Computer control
Note: HPLC devices from KNAUER only work with IP addresses, which
have been assigned by IPv4. IPv6 is not supported.
This chapter describes how to set up a chromatography system in a local
area network (LAN) and how a network administrator can integrate this
LAN into your company network. The description applies to the operating
system Windows® and all conventional routers.
Note: When using PurityChrom®, static IP addresses are needed
(see chapter 4.4 on page 13).
4.4.1 Setting up LAN
To set up a LAN, we recommend to use a router. That means the following
steps are required:
Process
1. On the computer, go to the control panel and check the LAN
properties.
2. Hook up the router to the devices and the computer.
3. Set up the router for the computer network.
4. Install the chromatography software.
5. Switch on the device and run the chromatography software.
Configure LAN properties (see section 4.4.2).
4.4.2 Configuring LAN settings
The LAN uses only one server (which is normally the router) from that the
devices automatically receive their IP address.
In Windows, power saving, hibernation, standby, and screen saver
must be deactivated.
Applies to all LAN devices: Disable the setting for the network adapter
in Device Manager ”Allow the computer to turn off this device to save
power”.
Process
1. In Windows, open <Network and Sharing Center>.
2. Double-click on <LAN connection>.
3. Click on the button <Properties>.
4. Select <Internet Protocol version4 (TCP/IPv4)>.
5. Click on the button <Properties>.

Process
6. Check the settings in the tab <General>. The correct settings for
the DHCP client are:
a) Obtain an IP address automatically
b) Obtain DNS server address automatically
7. Click on the button <OK>.
Connect devices (see section 4.4.3).
4.4.3 Connecting devices with LAN
A router 2has several LAN ports 3and one WAN port 4that can be
used to integrate the LAN into a wide area network (WAN), e.g. a com-
pany network or the Internet. In contrast, the LAN ports serve to set up a
network from devices 1and a computer 5. To avoid interference, we
recommend operating the chromatography system separately from the
company network.
Note: You will find patch cables for each device and the router in the
accessories kit. To connect the router to a LAN, an additional patch cable
is required, which is not supplied within the scope of delivery.
