The STS should be stored in closed rooms free of chemically aggressive vapours, temperature 0°C to +40°C (32°F to 104°F) and humidity lower than 90% at 20°C (68°F). OPM_STS_400_25A_100_1GB_V011 GE DE STS: installation and operating manual 1.1 (GB)
• Do not install the STS in an excessively humid environment or near water, relative humidity should not exceed 90% at 20°C (68°F). • Avoid spilling liquids or dropping any foreign object into the STS. OPM_STS_400_25A_100_1GB_V011 GE DE STS: installation and operating manual 1.1 (GB)
STS. CAUTION Wrong connection of the external sources to the STS may cause a fault inside the STS and unpredicted operation of external devices connected to the STS. OPM_STS_400_25A_100_1GB_V011 GE DE STS: installation and operating manual 1.1 (GB)
