Chemical resistance

Stop!
The resistance of the operating unit's 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 (keyboard, display,
touchscreen) to the listed chemicals.
For EPM−H5xx and EPM−H6xx operating units, Lenze offers protective foils with
an improved resistance against the listed chemicals.
