If you have special questions, consult ebm-papst forsupport.; Use the device in accordance with its degree of protection.Information on surface qualityThe surfaces of the products conform to the generally applicable industrialstandard. The surface quality may change during the production period.This has no effect on strength, dimensional stability and dimensionalaccuracy.The color pigments in the paints used perceptibly react to UV light overthe course of time. This does not however in any way affect thetechnical properties of the products. The product is to be protected againstUV radiation to prevent the formation of patches and fading. Changes incolor are not a reason for complaint and are not covered by the warranty.3.4 Mounting dataStrength class ofscrews8.8For screw clearance, see Chapter 3.1 Product drawing; Secure the screws against unintentional loosening (e.g. use self-locking screws).Any further mounting data required can be taken from the productdrawing or Section Chapter 4.1 Mechanical connection.3.5 Transport and storage conditionsMax. permittedambient temp. formotor (transport/storage)+80 °CMin. permittedambient temp. formotor (transport/storage)-40 °CItem no. 16328-5-9970 · ENU · Change 99670 · Approved 2018-06-06 · Page 5 / 10ebm-papst Mulfingen GmbH & Co.
