WARNING
If external electrical circuits that are subject to the danger
of physical contact are incorrectly connected to the relay
contacts, there may be a danger of life threatening electric
shock. Electrical circuits are regarded to be subject to the
danger of physical contact when there are voltages higher
than the Safety Extra Low Voltage (SELV).
Pay attention to the following points during installation:
Electrical circuits subject to the danger of physical
contact must only be connected by a qualified electri-
cian.
Electrical circuits subject to the danger of physical
contact must only be connected when they are voltage-
free.
The terminal strip of the MIQ/R6 output module has two
segments for relay outputs with three relay connec-
tions each (R1-R3 and R4-R6).
If electrical circuits subject to the danger of physical
contact are switched with a relay, no circuit that is not
subject to this danger (e. g. the MIQ/CHV module) may
be operated in the same output segment of the MIQ/R6.
For such applications use the second output segment
of the MIQ/R6.
Switching voltages and switching currents on the relay
contacts must not exceed the values specified in chap-
ter 6 T
ECHNICAL
DATA
. Protect electrical circuits against
currents that are too high with an electrical fuse.
Only single-phase consumers can be switched with the
relays. Under no circumstances must multiphase con-
sumers be switched with the aid of several relays (ex-
ample three-phase current driven pumps). Always
switch multiphase consumers via a protective relay.
The MIQ/R6 may only be opened after the installation if
all external voltages have been previously switched off.
