ABB Panel 800 - PP846 Hardware and Installation

and the supplier should be notified promptly if problems are found. When installing the equipment, 

it should be gently held and put down to avoid damage caused by falling equipment. 

Pay attention to static electricity protection during installation, especially when installing sensitive parts such as internal Compact Flash memory cards 

and expansion modules, to prevent static electricity from damaging the device.

Operation specification and personnel qualification: 

The installation must be carried out by qualified personnel to ensure that the installation is in line with the specifications to avoid damage to 

the equipment or safety accidents caused by improper operation. The installation process should be carried out in strict accordance with the instructions, 

follow the operating steps and requirements to ensure the accuracy and reliability of the installation.

Wiring and connection points

Electrical grounding:

Ensure that the operator panel and controller system have the same electrical ground (reference voltage level), 

otherwise communication errors may occur.

Use M5 screws and a grounding conductor with a cross section of at least 2.5mm² for the grounding connection, 

and keep the grounding conductor as short as possible.

Cable selection and separation:

Use only shielded communication cables and separate the high-voltage cables from the signal 

and power supply cables to reduce electromagnetic interference and to ensure the stability of the signal transmission and the safety of 

the equipment operation.

When connecting the power supply, make sure that the voltage and polarity are correct to avoid equipment damage due to wrong connection.

If the 24V power supply is also used to supply power to other units, it should be checked carefully to ensure that the 24V feed is safe 

and meets the relevant safety standards, such as the SELV standard.

Other Precautions:

The panel should be brought to ambient temperature before installation, and if there is condensation, 

ensure that it is dry before connecting the power supply.

When connecting the cables, follow the specified sequence of operation. After completing the installation, 

carefully remove the film from the panel display to prevent static electricity from damaging the panel.

Mode switch operation:

The four mode switches on the operation panel must be in the OFF position when in use and should not be touched by unqualified personnel.

To switch modes, disconnect the power supply, set the switches and then reconnect the power supply.

Different mode switch combinations have different functions, such as system recovery, image loading, service menu, etc. 

Improper operation may result in data loss or equipment failure.
