Unit description
The expansion module may only be
connected to a base unit from the
PNOZmulti modular safety system.
The PNOZmulti modular safety system
is used for the safety-related interrup-
tion of safety circuits and is designed
for use in:
`Emergency stop equipment
`Safety circuits in accordance with
VDE 0113 Part 1 and EN 60204-1
Safety features
The relay conforms to the following
safety criteria:
`The circuit is redundant with built-in
self-monitoring.
`The safety function remains effec-
tive in the case of a component fail-
ure.

Function description
The expansion module provides addi-
tional inputs.
The function of the inputs on the safety
system depends on the safety circuit
created using the PNOZmulti Configu-
rator. A chip card is used to download
the safety circuit to the base unit. The
base unit has 2 microcontrollers that
monitor each other. They evaluate the
input circuits on the base unit and ex-
pansion modules and switch the out-
puts on the base unit and expansion
modules accordingly.
The online help on the PNOZmulti
Configurator contains descriptions of
the operating modes and all the func-
tions of the PNOZmulti safety system,
plus connection examples.
Wiring
The wiring is defined in the circuit dia-
gram of the PNOZmulti Configurator.
Please note:
`Information given in the "Technical
details" must be followed.
`Connection terminals I0 ... I7 are in-
puts
`Power for the safety system and in-
put circuits must always be provid-
ed from a single power supply. The
power supply must meet the regu-
lations for extra low voltages with
safe separation.
`The test pulse outputs on the base
unit must be used to detect shorts
across contacts.
`Use copper wire that can withstand
75 °C.

Terminal configuration
Installation
`The safety system should be in-
stalled in a control cabinet with a
protection type of at least IP54. Fit
the safety system to a horizontal
DIN rail. The venting slots must face
upward and downward. Other
mounting positions could damage
the safety system.
`Use the notches on the back of the
unit to attach it to a DIN rail. Con-
nect the safety system to the DIN
rail in an upright position, so that
the earthing springs on the safety
system are pressed on to the DIN
rail.
`To comply with EMC requirements,
the DIN rail must have a low imped-
ance connection to the control cab-
inet housing.
