3.5.2 Stacked mounting of DIQ and MIQ modules

For optimum stability, a maximum of three modules (DIQ/MIQ) can
be mounted in any one stack. Only one MIQ power supply module
may be mounted per module stack.
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.
Variant 1 - stack expansion forwards.
The back of an MIQ module is
attached to the lid of another
MIQ module (see page 18).
Variant 2: - stack expansion
backwards.
The lid of an MIQ module is attached
to the back of another MIQ module
(see page 22).
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.
In the case of panel mounting, the front MIQ module can only be
installed individually in the switch cabinet aperture. Only then can
further MIQ modules be added to its back (variant 2). If necessary,
dismantle the front MIQ module from an already mounted stack
before mounting.
 2 x ISO blind nuts (M4)
 2 x cheese-head screws (M4x16) with plastic washer
 1 x contact base with two plastic tapping screws.
 Phillips screwdriver.
Both installation variants are described below. To dismantle a module stack,
proceed in the reverse order to mounting the stack.
