2.
Option IL (Isolating lacquer)
To protect the electronic components of the power feed/feedback unit from
pollution of the cooling air, all printed circuit boards may be coated with an isolating lac-
quer. This option improves the service reliability, but it doesn’t release the user from the
duty to observe the in chapter 3.2 specified application conditions.
3.
Overvoltage-suppressor
If the power feed/feedback unit (as well as a controller) is connected to ungrounded mains
supply, it only may be run, either if it is connected via an isolating transformer or if the
plant is protected by overvoltage suppressors. But also with grounded mains supply it may
be useful to install overvoltage suppressors, if it is possible, that voltage peaks occur. For
choosing the best overvoltage suppressor for your specific application, please get in con-
tact with one of our technicians.
