4.5.2 Anti-condensation heater
The anti-condensation heater is designed as a panel heater which also acts
as the front cover of the swing frame.
The design of the motor-drive unit and panel heater ensures that air circu-
lates inside the motor-drive unit and therefore that there is a constant interior
temperature which is always higher than the outside temperature.
4.5.3 Swing frame/terminal rail
The swing frame protects all electrical and mechanical parts of the motor-
drive unit behind the swing frame against accidental contact.
The terminal rail behind the swing frame enables easy electrical connection
of the motor-drive unit. Vertically arranged cap rails with the correspondingly
mounted terminal bars ensure that the connection wiring is easy to install.
