Once you have received the delivery please carefully unpack the switching devices and check for any transportation damage. Should you determine any damage please report this immediately and indicate the carrier. After unpacking, clean the switching devices and accessories to remove any contamination from packing material and protect against moisture and contamination prior to installation. To transport the switching devices only hold at the frame and never touch the contact blades etc. Thoroughly clean the switches and actuator elements prior to putting into operation to remove dust and installation swarf and wipe all insulating parts with a clean dry cloth. The switches are designed for normal operating conditions in compliance with EN 62271-1 Class "Minus 5 Indoors". The max. ambient temperature is 40°C; the average value over 24 hours is max. 35°C. The values on insulation strength are related to sea level. For altitudes of up to 1000 m any reduction in insulation caused by the reduced insulating property of the air is insignificant and can be ignored. For installation at altitudes above 1000 m it is necessary to correct the values given for the rated powerfrequency withstand voltage and the rated lightning impulse withstand voltage according to DIN EN 62271-1
