7 Hardware installation
7.1
Building Technologies
CPS Fire Safety
There are various possible installation scenarios. Namely:
Installation of NK8237 in existing cabinets.
⚫
a. DIN-rail mounting (typical) in plastic housing.
b. Mounting of the NK8237 board in the control unit housing using card holders
(NKA8011-A1 required).
Installation of a complete NE8001 cabinet including the NK8237 unit.
⚫
Environmental requirements
The NK823x units should always be installed in a protective housing, away from
dust, high temperature and humidity, vibrations and impacts.
Conditions and power supply should match the specific requirements given in the
Technical Data section on the specific NK823x model datasheet.
Network requirements
Ethernet IEEE 802.3, 10Base-T (100Base-T also possible for NK823x), RJ-45
⚫
connection
Fixed IP address (DHCP not supported)
⚫
Stable network with guaranteed transmission characteristics (no down-times for
⚫
maintenance, predictable network load).
For the special mounting kits, refer to the NK8000 datasheets.
WARNING
The installation must be carried out by technically qualified personnel.
