4. Installation

WARNING: Danger!
Never carry out work when mains voltage is present !
The MSI 100 programmable safety controller is equipped with a DIN rail
connector interface on its mounting side for standard extension modules.
Gateways for transmitting standard diagnostic values can be connected via the
DIN rail connector. The DIN rail connector means there is no need for cross-
wiring between the safety controller and the extension modules.
CAUTION:
• You must use the yellow DIN rail connector AC-MSI-TCS
(Order No. 547821) for connecting the MSI 100 programmable
safety controller.
• Do not use a terminating connector.
• You must use the gray DIN rail connector AC-MSI-TC
(Order No. 547823) for connecting standard extension
modules (e.g. PROFIBUS gateways).
• Installing the devices on and removing them from the DIN rail
connector is only permitted in a de-energized state.
• Standard extension modules must be installed on the
left-hand side of the safety controller.
• When using DIN rail connectors, connect the required number together
and push them onto the DIN rail.
• When positioning the MSI 100, please ensure that it is aligned correctly
with the DIN rail connector on the DIN rail.
• When using the MSI 100 programmable safety controller, yellow and gray
DIN rail connectors should be installed side by side.
• Place the yellow safety controller on the yellow DIN rail connector and the
gray extension modules on the gray DIN rail connector.

5. Connection notes

WARNING: Danger!
Never carry out work when mains voltage is present!
Generally speaking, there are a large number of applications which use multiple sensors or controlling
devices. Depending on the size of the machine or system, a considerable amount of cabling may be
required to wire the sensors.
Make sure that the specified cable lengths are not exceeded, so as to ensure error-free operation
of the safety circuit.
In order to comply with the UL, use copper cables that are designed for operating temperatures of 75°C.
To ensure the contacts are reliable and touch proof, strip the cable ends as shown below (Fig. 4).
