Do not use a megger etc., for insulation test of the system. Using a megger
can break internal electric parts.
Always disconnect wirings connected to the system before testing related
power distribution lines with a megger.
5.3 Cleaning the operator panels and the cabinet surface
The surface of the display is likely to keep foreign materials due to
electrification.
Use a vacuum cleaner with a soft brush to avoid damaging the buttons
and the panel. If required, clean the buttons and panel with a non-abrasive
cloth moistened with mild soap solution.
5.4 Check warning label
Check and clean warning labels to read legibly.

The connectors should be checked by visual inspection only. Push the
connector plugs into the connector. If the connector plugs are equipped
with a lock, ensure that this is in the correct position.

Vibration and shock may cause mechanical parts to loosen. All fastening
screws should therefore be checked regularly and eventually tightened.

intervals.
