EN PowerBox
Connections and Outputs (pics. 2 and 3): Connect the rubber hose with the hose
clips.
NOTE! Picture 2 only shows connection to a incoming pipe with a "flange"
(equivalent to the PowerBox).
NOTE! In order to prevent the connection sliding apart the hose clips A must be
located on the correct side of the pipe's "flange" B. The tightening torque of the hose
clips must be 6-8 Nm.
Connect the control signal cable (pic. 3, A) if fan control via the dampers is required.
• Compressed air (pics. 4 and 5): Three ¼" connections are available of which
two is adjustable (A) and one has a none adjustable feed pressure (B). These are
complemented with connections suitable for the purpose. The output air pressure (A)
is adjusted via the lever (C) in picture 5 and is shown on the manometer (D).
Connecting: First choose suitable connections for the outputs. Then connect the ½"
hose to the compressed air supply, max 10 Bar.
Power supply (only on some types): The PowerBox can have several types of
•
electrical sockets. The protective bonding circuits continuity should be checked after
the installation. Pay attention to any national or local standards.
Electrical installation: Sockets and cables vary depending on type.
NOTE! The electrical installation must be done by an authorized electrician.

Information about voltage/current is on the sockets, (pic. 6 A), while the socket (pic. 6 B)
is 1-phase 220V. All the electrical cables should be connected to the same power source
(to avoid potential difference). Cables belong to sockets according to pics. 7-8, tie the
cables into the groove (A) using tiewraps, pic. 9.
