Mounting
The YUAA module can be mounted to either a standard 35 mm (1.38 in) DIN-rail or directly mounted to a panel using the
two 5.2 mm (0.21 in) slotted holes on the module base.
Mounting Dimensions
The module can be mounted with the terminal strips either left or right facing. It cannot be mounted with the terminals top or
bottom facing as this impedes the convection flow required to ensure adequate cooling of the internal components. There are
no spacing requirements to ensure adequate module cooling. Spacing the modules at the standard Mark VIeS spacing of 170
mm (6.7 in) will allow for a small gap between the modules but is not required for cooling purposes.
The module can be assembled to standard 35 mm (1.38 in) DIN-rail (7.5 mm [0.30 in], and 15 mm [0.60 in] height). The
module position relative to the DIN-rail center line is 23 mm (0.9 in). The module base is designed to lock onto the DIN-rail
and resist sliding without the use of rail stops. Removal and reinstallation or transfer of the module from one rail to another
can reduce the effectiveness of the locking features. In such cases, the addition of rail stops or base replacement may be
required.
