9.1 Chemical resistance
Stop!
The resistance of the surface against acid food (e.g. tomato juice,
lemon juice) is low. For this reason remove soilings immediately,
otherwise the surface may be damaged.
The following table shows the resistance of the surfaces (keypad, display, touch
screen) to the listed chemicals.
For the operating units EPM-H5xx and EPM-H6xx, Lenze offers protective foilswith
an improved resistance against the listed chemicals.
