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 °
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.
