8.1.1 Overview

Checklist

Before starting up the device for the first time, go through the following checklist:

• Have you taken into account the proper ambient and environmental conditions for the

device and the connected I/O modules, as described in the technical information?

• Have you found out how to connect the equipotential bonding?

• Have you found out how to connect the power supply?

• Read over this information in the respective "Connecting" chapter of the control unit and

computer unit operating instructions. Please follow all guidelines.

Caution

Condensation

When transporting the device at low temperatures, prevent condensation from forming on

or in the device. The same applies when the device is subjected to extreme changes in

temperature. Wait 12 hours before switching the device on.

Before starting up the device, allow it to adjust slowly to room temperature. Do not

subject it directly to heat radiation from a heating device, however.

I/O modules

Connect the I/O modules using shielded cable and metal plugs. Otherwise the operating

license expires. Secure the plug of the interface cable on the housing of the device. This

improves the electrical shielding.

Start up

Do not switch off the device during the start up. Otherwise parts of the software will be

lost which are necessary for trouble-free operation.

Use the default values in the BIOS. Otherwise the operating system will not be installed

properly.
