N
Nominal torque The specied value for the torque of the screws (screw connection) must not be
exceeded.

O
Operating temperature Permissible ambient temperature – relative to a specic relative humidity–
at which a product should be operated at nominal load.
x x
Operational voltage range Permissible range of the input voltage depending on the ambient temperature.
Operating voltage range curve in the data sheet:
The top part of the range is specied by the maximum voltage;
the lower part of the range is specied by the response/minimum voltage
Curve 1: Response/minimum voltage U0 (without pre-excitation)
Curve 2: Response/minimum voltage U1 (after pre-excitation)
Curve 3: Maximum voltage U2, contact current = 0 A
Curve 4: Maximum voltage with contact current I

The diagrams are valid for the single mounting of relays without thermal
interference and connection wiring according to IEC 61810-1; unless otherwise
indicated, the data is displayed without contact load and without taking into
account the temperature rise due to the contact current.
If no operating voltage range curve is specied in the data sheet, the tolerances
in per cent (%) can be found in the rated control voltage characteristic.
The use of a relay with an excitation voltage other than the rated coil voltage can
lead to a reduced electrical lifespan (mechanical and dynamic effects).

Plug-in cycles Sockets and accessories are designed for 10 insertion cycles without electrical
load – unless otherwise specied.
