Stop!
Incorrect handling destroys the modules!
Modules may be destroyed if live during installation.
Protective measures:
l Make sure the supply voltage is disconnected before you insert
modules into the backplane bus.

Fig. 6.1−2 Mounting the module on the DIN rail
 Mount the DIN rail. Provide enough mounting clearance for the modules
(Fig. 6.1−1):
At the top: Min. 80 from the middle of the DIN rail
At the bottom: Min. 60 mm from the middle of the DIN rail
Press the backplane bus onto the DIN rail until it safely engages
‚ Lower the module on to the DIN rail at an angle of approx. 45 °
ƒ Turn the module downward
„ Connection to the backplane bus is established once the module has audibly
engaged with the DIN rail.
)
Note!
l The backplane bus is available in single (EPM−T910), double
(EPM−T911), quadruple (EPM−T912) and octuple (EPM−T913)
versions.
– In order to determine the number of slots, add a 1 to the
backplane bus versions you want to use, e. g.:
single
(EPM−T910)
+ octuple
(EPM−T913)
+ 1 = 10 slots.
l The modules are always arranged from left to right and must
always start with the CAN gateway module.
l Modules must always be plugged directly next to each other.
Free slots are not permissible since this would interrupt the
backplane bus.
l A module is electrically connected only once it has audibly
engaged.
l Slots to the right of the last module may remain unassigned.
l The number of modules is limited to max. 32.
