5 Assembly and Installation
5.1 Assembling the MATRIX control panel OP71
5.1.1 Mounting MATRIX control panel OP71 C (IP20)
The casing of the MATRIX control panel OP71C (IP20) is suitable for on-wall and in-
wall sockets mounting.
Electrical hazard!
The electrical installation and (dis)assembly of the MATRIX control panel
OP71 may only be carried out by qualified electricians in compliance with
the given operation manual and current VDE regulations.
•Before drilling, ensure that the drilling area is free from electrical cables and
pipes.
•Only indoor mounting of the OP71 MATRIX control panel is allowed.
•Do not connect the MATRIX control panel OP71 to an external voltage.
NOTICE!
Use the drilling template for the wall mounting of the MATRIX.control panel
OP71 (see „Drilling Templates“ on page 103).
Make sure that the mounting plate is not deformed during installation.
NOTICE!
When mounting the MATRIX control panels in an flush-mounted socket,
especially hollow wall socket, ensure that the room temperature measu-
rement is not distorted. To avoid draught, provide appropriate insulation of
the flush-mounted socket, if necessary.
If the control panel is mounted into a flush-mounted socket, edges of the
mounting plate may remain visible, which depends on the used socket and
the way it is mounted.
If necessary, use paint, wall paper, or similar means to prepare the installa-
tion surface.
It also possible to hide the visible edges of the mounting plate by using a
wall-lamp socket with vertical mounting dimensions (screw clearance) of
60°mm
When tightening the fixing screws the mounting plate must be level, flush-
fitting and is not deformed by tightening the screws.

5.1.2 Mounting MATRIX control panel OP71 I (IP54)
The casing of the MATRIX control panel OP71 is suitable for mounting on the wall. The
wires are routed through three membrane grommets from below.
•Use a screwdriver to release the front panel (1)
from the mounting plate (2) on the bottom side
of the MATRIX control panel OP71.
Ensure that the mounting plate is not deformed.
•If required, unscrew the mounting screws from
the mounting plate (3) on the surface-mounted
socket (1).
•Lift the mounting plate (3) away from the sur-
face-mounted socket (1).
•Adhere a gasket (2) on the bottom part of the
mounting plate (3).

5.2 Integration of MATRIX BSZ circuit board
The MATRIX BSZ circuit board is an intermediate terminal to be used if two wires are
connected using one terminal in MATRIX OP5x (IP20 and IP54) control panels
(necessary for loop-through of the network).
5.2.1 Mounting MATRIX BSZ in the flush-mounted socket
•Use the groove to break off the bottom part of the circuit
board and place it in the flush-mounted socket.
•Route the wires through the flush-mounted socket and con-
nect the bus cable (refer to cable recommendation for MA-
TRIX.Net) as follows:
Tab. 5-1: Terminal designation
•Use the supplied cable to connect the circuit board with the
terminals of the mounting plate of the MATRIX OP5XC
control panel, as illustrated in Tabelle 5-1 on page 17.

5.3 Installation of the MATRIX control panel OP71
For connecting the MATRIX control panel OP71 only the following cross sections may
be used:
The following steps are required to connect the MATRIX control panel OP71:
– Connect mains electrical supply
– Connect MATRIX.Net
•Remove insulation from the wires and fasten each wire
according to the wiring diagram:
•Hook the front panel over the top of the mounting plate.
Apply light pressure to the bottom of the front panel until it
snaps into place.
Conductor type Number of conductors per
terminal
Cross-sections min to max
Rigid conductor cross-section 1 0.22 to 0.5 mm2
Flexible conductor cross-section 1 0.22 to 0.5 mm2
0.22 to 0.5 mm2 tinned
0.22 mm with wire end sleeve (4-side crimping
tools, e.g. Knipex pliers/tongs 975304)
Note!
For setting up the MATRIX.Net use only data transfer cable certified according
to DIN 19245 T3 and EN 50170 as twisted-pair wire with braided shield.

Electrical hazard!
The MATRIX control panels OP71 are connected to the power supply of the air
treatment units. Therefore, the control panel itself can not be powered down!
Switch off the power to the air treatment units and make sure they are isolated,
earth and short-circuit them, block off or shield any neighboring or live com-
ponents.
Non-compliance can lead to death or serious injury.
