When disposing of this equipment, do so in a safe manner according to
local regulations. It is recommended that incineration and disposal to water
courses is avoided. Ensure the relay is in de energized condition and take
precautions to avoid short circuits.
TECHNICAL SPECIFICATIONS FOR SAFETY
1. Protective class
IEC 60255-27:2005 Class I (This equipment requires a protective
conductor (earth) connection to ensure
user safety.
2. Environment
IEC 60255-27:2005 Pollution degree 2 (Normally only non-conductive pollution
occurs except occasionally a temporary
conductivity caused by condensation is to
be expected.)
3. Overvoltage Category
IEC 60255-27:2005 Category III (The auxiliary energizing circuits of the
equipment are connected to a common
battery, common mode transient voltages
of a relatively high value may appear on
the supply leads, and differential mode
voltages may arise from switching in other
circuits connected to the same battery
source.
4. Contact data Test voltage across open contact: 1 kV DC for
1 minsource.
