Installation

There are various possible NK8237 installation scenarios. Namely:

Installation of NK8237 in existing cabinets

DIN-rail mounting (typical) in plastic housing.

Mounting of the NK8237 board in the control unit housing using card

holders

(NKA8011-A1

required).

Installation of a complete NE8000 cabinet including the NK8237 unit

The

installation

must be carried out by technically

qualified personnel

NK8237 Hardware Installation

Installation
1.

Install the NK8237 unit on the DIN rail.

Connect fire subsystems on the Ethernet line.

Connect the Modbus serial device line or the Modbus station Ethernet line.

If used, connect the power supply supervision module DF8090.

Connect power supply. See Fig. 10 p. 18 if using a DF8090 supervision module.

Do not connect or disconnect any device when the device is powered on!
