WARNING!
Protection of radio reception
Possible consequence: fatal or very serious inju‐
ries.
This equipment with communication interface is not
intended to be used in residential areas and
cannot guarantee appropriate protection of radio
reception in these environments.
WARNING!
Electrical voltage at the output relays
Cause: Output relays 1 and 2 are not adequately
isolated from each other. This means that there is
not always sufficient electrical isolation between
the relays.
Possible consequence: fatal or very serious inju‐
ries.
Measure: Only ever connect one type of voltage to
output relays 1 and 2. Connect either low voltage
or extra-low voltage. The use of low voltage on one
relay and extra-low voltage on the other is not per‐
mitted, as isolation of the relays cannot be guaran‐
teed.
Moisture on the contact points:
It is essential that appropriate construction and technical meas‐
n
ures are used to protect the connecting plugs, cables and ter‐
minals from moisture. Moisture on the contact points can
adversely affect the operation of the device.
