Mounting and cabling
3.1.2 Mounting
EP9214 modules are mounted using two M3 bolts in the mounting holes located in the corners or using two
M4 bolts in the centrally located mounting holes.
The bolts must be longer than 15 mm. The mounting holes in the modules have no thread.
Note
Protect connectors against soiling
Protect all module connections from soiling during installation!The protection classes IP65,
IP66, IP67 (in accordance with EN 60529) are ensured only if all connectors are wired or
sealed! Unused connectors must be sealed with suitable protective caps (see Beckhoff cat-
alogue for connector sets and protective caps)!
Note
Cooling plate
The EP9214 module has a cooling plate on the underside. For the effective dissipation of
the resultant power loss, the box must be bolted to a metal base, e.g. the machine bed, if
possible making contact over the entire surface.A temperature-related automatic switch-off
of the box can occur if care is not taken to ensure that the power loss from the module is
dissipated via the cooling plate. A corresponding temperature error bit is then set!
Note when mounting that the overall height is increased further by the fieldbus connections. See the
Accessories section
