5 HW Installation
This section lists the NK8000 hardware installation requirements, and details how
to install them.
There are two possible installation scenarios:
1. Installation of NK822x in an existing cabinet
a. NK822x DIN-rail mounting (typical)
b. Mounting of the NK822x euro-size main board in the control unit housing
of CS11/CS440, CS6 or SI410 using mounting kits (alternative mounting
option if DIN-rail mounting is not possible)
See the System component list on page 54.
2. Installation of a complete NE8000 cabinet including the NK822x unit
Both scenarios will be discussed in the next sections.
The installation must be carried out by technically qualified personnel.
5.1 Installation of NK822x units
5.1.1 NK822x hardware requirements
Environmental requirements
The NK822x units should always be installed in a protective housing, away from
dust, high temperature and humidity, vibrations and impacts. Conditions should
match the specific requirements given in the Technical data section on p.57.
Network requirements
– Ethernet (IEEE 802.3, 10Base-T, half-duplex operation, no auto-sensing or
auto-negotiation, RJ-45 connection
– NK822x requires fixed IP addresses (DHCP not supported)
– Stable network with guaranteed transmission characteristics
(no down-times for maintenance, predictable network load)
NK822x power requirements
Item Power supply requirement
Input voltage (DC power supply to NK8225 board) 10-33 VDC
Power (NK8225 processor board) 6,34 W
Power (fully equipped NK8225) 8,34 W
NK822x housing for DIN-rail mounting
Width 180 mm
Height 108 mm (without connectors)
Depth 80 mm
Weight 0,7 kg (fully equipped)
NK822x main board for internal mounting (CS11, CS6, SI410)
Width 160 mm
Height 100 mm (without connectors)
Depth – Mainboard only: 28 mm
– Mainboard + LON: 41 mm
– Mainboard + LON + serial add-on: 55 mm
For the mounting kits for CS11/CS440, CS6, and SI410/SI420 see the System
component list on page 54.
