To mount the PSR-TRISAFE-S safety module, proceed as follows:
Mounting a 35 mm DIN rail 1. The safety module should only be mounted on 35 mm DIN rails according to
DIN EN 60715. To avoid contact resistance only use clean and corrosion-free DIN rails.
Mounting PSR TBUS DIN
rail connectors (optional)
2. To use PSR TBUS DIN rail connectors to create a connection station with a system
power supply unit or with extension units, proceed as follows:
– Connect together the required number of PSR DIN rail connectors for the
connection station (see Figure 3-9, A).
– Snap this group of PSR DIN rail connectors onto the DIN rail (see B and C).

3. Place the module onto the DIN rail from above as shown in Figure 3-10 so that the
upper holding keyway of the module is hooked onto the top edge of the DIN rail.
When using PSR DIN rail connectors, ensure that the contact opening in the base of the
module is aligned correctly over the contact block of the PSR DIN rail connector.
