Short-circuit protection only. RESISTRON tempera-
ture controller not protected.
!
Relay Ka
For „HEAT ON-OFF“ function (all-pole) or
„EMERGENY STOP“.
Line filter
The filter type and size must be determined according the
load, the transformer and the machine wiring (
ROPEX
Application Report).
Do not run the filter supply wires (line side) parallel
to the filter output wires (load side).

RESISTRON temperature controller
RES-430.
Impulse Transformer
Designed according to VDE 0570/EN 61558 (isolating
transformer with reinforced insulation). Connect core to
ground.
Use transformers with one section bobbin. The
power, duty cycle and voltage values must be deter-
mined individually according to the application (
ROPEX
Application Report and „Accessories“ leaflet for impulse
transformers).
!
Wiring
The wire cross-sections depend on the application
(
ROPEX Application Report).
Guide values:
Primary circuit:
min. 1,0mm², max. 2,5mm²
Secondary circuit: min. 2,5mm², max. 4,0mm²
Twisting (>20turns/meter) is recommended
to improve EMC.
