NOTE!
In the event of a MAC-D-Min malfunction, the "Collective fault" light on the TSS or TS panel and
the MAC-FC controller issues a fault signal to the CSP. If a controller malfunction is detected,
inform the SMAY service immediately. Do not repair or replace the controller yourself. This can
only be done by SMAY service or an authorised SMAY service.

PZ connection box
The PZ connection box is used to connect damper actuators with MAC-D-Min controller
and to connect power supply for damper actuators. For the power supply of the damper actuators,
a 3A quick-acting axial fuse is installed.
There are four types of boxes: PZ1, PZ2, PZ3 and PZ4. One NMQ24A-SR actuator can be connected
to PZ1, two NMQ24A-SR actuators to PZ2, three NMQ24A-SR actuators to PZ3, four NMQ24A-SR
actuators to PZ4. The boxes should be mounted in the same zone as the MAC-D- Min regulator,
in its immediate vicinity. The PZ box should be installed so that it is not directly exposed to sunlight
or precipitation (when installed outside the building, it should be covered).
The box housing is made of halogen-free material.
When mounting to the concrete base, use the dowels supplied with the MKR6x32 screw (1). The
use of self-drilling screws is permitted if the box is mounted to sheet metal substrates. To
maintain IP 55 protection, the hole in the box must be made with a screw that will fix the box. The
assembly is carried out as shown in Figure 14.9.
