Installation
4. Connect the cables in the specified order, according to the drawing and steps
below.
Caution:
• Ensure that the operator panel and the controller system have the same electrical
grounding (reference voltage level), otherwise errors in communication may
occur.
• The operator panel must be brought to ambient temperature before it is started
up. If condensation forms, ensure that the operator panel is dry before connecting
it to the power outlet.
• Ensure that the voltage and polarity of the power source is correct.
• Use only shielded communication cables.
• Separate high voltage cables from signal and supply cables.

5. Carefully remove the laminated film over the operator panel display, to avoid
static electricity that could damage the panel.
Note:
Only for iX T7A panels with part number 630000201:
When connecting the operator panel to the power outlet for the first time, make
sure not to interrupt power for a minimum of 48 hours in order to charge the battery
completely. After that, the battery may be charged partly during a shorter period of
time.
