Installation MIQ/CR3; DIQ/CR3
12 ba64107d13 03/2018
3.6 Connections to the relay and current outputs
WARNING
No free wires are allowed to project into the housing. Oth-
erwise, there is a danger that areas safe to contact could
come into contact with dangerous voltages. Always cut
off any wires that are not in use as closely as possible to
the cable gland.
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
electrician.
 Electrical circuits subject to the danger of physical
contact must only be connected when they are voltage-
free.
 The terminal strip of the MIQ/CR3; DIQ/CR3 output
module has two segments for relay outputs with three
relay connections 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/
CR3; DIQ/CR3. For such applications use the second
output segment of the MIQ/CR3; DIQ/CR3.
 Switching voltages and switching currents on the relay
contacts must not exceed the values specified in
chapter 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
consumers be switched with the aid of several relays
(example three-phase current driven pumps). Always
switch multiphase consumers via a protective relay.
 The MIQ/CR3; DIQ/CR3 may only be opened after the
installation if all external voltages have been
previously switched off.
