IMPORTANT GENERAL INFORMATION
(i) Air and creepage paths/Operating
voltage
The admissible operating voltages depend on
the individual applications and the valid
national and other applicable safety
regulations.
For this reason the air and creepage path data
are only reference values. Observe reduction
of air and creepage paths due to PC board and/
or harnessing.
(ii) Temperature
All information given are temperature limits.
The operation temperature depends on the
individual application.
(iii) Other important information
ITT Industries continuously endeavours to
improve their products. Therefore, ITT
Industries products may deviate from the
description, technical data and shape as shown
in this catalog and data sheets.
(iv) Harnessing and Assembly Instructions
If applicable, our special harnessing and/or
assembly instruction has to be adhered to.
