4. Installation
WARNING: Danger!
Never carry out work when mains voltage is present !
The MSI 200 programmable safety controller is equipped with two DIN rail
connector interfaces on its mounting side for extension modules.
With the DIN rail connector, gateways for transmitting non-safe diagnostic
values can be connected at the left of the safety module.
The safe extension modules are connected at the right of the safety module.
CAUTION:
• You must use the yellow DIN rail connector
AC-MSI-TCS
(Order No. 547821) for connecting the MSI 200 programmable
safety controller and the safe extension modules.
• 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.
• The safe extension modules have to be connected at the right
of the safety controller.
• 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 200, please ensure that it is aligned correctly
with the DIN rail connector on the DIN rail.
• Place the yellow safety controller and the safe extension modules on the
yellow DIN rail connectors and the gray extension modules on the gray DIN
rail connectors.
• Plug the extension modules together in such a way that all non safety-ori-
ented gray modules are mounted to the left and all safety-oriented yellow
modules are mounted to the right.
• Place the included quick-mounting end clamp at the right next to the last
device of the MSI system. Thus accidentally connecting additional DIN rail connectors is prevented.
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).
