Special considerations
1.1 Over-temperature contact and load disconnect
ecosine
®
harmonic filters provide basic safety monitoring:
▪
temperature detection level for each inductive component (over-temperature contact)
This alarm indication requires adequate reaction in order to prevent possible system damage (i.e. cable or
cabinet overheating). Either the cabinet safety monitoring unit must make use of the alarm contact, or the
contact must directly control a stop function of a connected motor drive (refer to motor drive user manual
for applicability).
Important:
Connection and use of the over-temperature contact is required for safe operation. An engaged (open)
over-temperature contact must lead to immediate load shutdown and investigation of the problem.
