2 Installing the device

This chapter explains how to install the device.

2.1 DIN rail installation

The HAI-P200-4G ships with a DIN rail bracket pre-installed by default.

Steps:

1. Position the DIN rail bracket’s side facing the rail to install it on. Slide the upper part of the bracket onto the rail’s upper edge.

   

2. Press the locking tab on the lower part of the bracket until it clicks onto the rail.

Note:

• No additional tool is required for this installation.
• The DIN rail fixing guarantees optimal stability in an industrial environment.

4 Starting the device

4.1 First system start

The HAI-P200-4G has no power switch. The system starts automatically once power is applied.

Indicators:

• PWR (red): on = normal power supply.
• ACT (green): blinking = successful start.
