3.5.2 Stacked mounting of MIQ modules:
Note
For optimum stability, a maximum of three MIQ modules can be mount
-
ed in any one stack. Only one MIQ power supply module may be
mounted per module stack.
Mounting direction MIQ modules can be stacked on top of one another from both sides. All
the required installation materials are contained in the scope of delivery
of the MIQ modules.
Which variant is suitable for a specific case depends on whether and
how an MIQ module is already permanently installed at a location (e.g.
on a wall or in a panel), among other factors.

2 x ISO blind nuts M4

(variant 2). If necessary, dismantle the front MIQ module
from an already mounted stack before mounting.
