WARNING!
Mains voltage
Possible consequence: Fatal or very
serious injuries
If mains voltage is connected to one
of the terminals XR1-XR3 or XP, then
no protective low voltage may be con‐
nected to any other of these terminals
(SELV).

contacts
Typical AC current application with an
inductive load:
n 1) Load (e.g. alpha motorised pump)
n 2) RC-protective circuit
– Typical RC protective circuit at
230 V AC:
– Capacitor
[0.22µF/X2]
– Resistor
[100 ohm / 1 W]
(Metal-
oxide (pulse-resistant))
n 3) Relay contact (XR1, XR2, XR3)
