4 Installation
WARNING! Risk of personal injury
The Power Box must be mounted according to
the installation instructions.
See Figure 1 to Figure 9 .
NOTE!
The pictures may vary due to different types.
• Figure 1 shows two vacuum outputs (A) female, dia-
meter 38 mm with swivel function and the sliding
valves (B) with on/off function. The sliding valves al-
low machines to be constantly connected to the va-
cuum outputs.
• Figure 2 and Figure 3 show connections and Out-
puts. Connect the rubber hose with the hose clips. In
order to prevent the connection from sliding apart
from 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.
NOTE!
Figure 2 only shows the connection to an in-
coming pipe with a “flange” (equivalent to
the Power Box).
Connect the control signal cable, Figure 3 item A, if
fan control via the dampers is required.
• Figure 4 and Figure 5 show three ¼” connections, of
which two are adjustable (A) and one has a none ad-
justable feed pressure (B). These are complemen-
ted with connections suitable for the purpose. The
output air pressure (A) is adjusted via the lever (C) in
Figure 5 and is shown on the manometer (D).
Connecting: First, choose suitable connections for
the outputs. Then connect the ½” hose to the com-
pressed air supply, max 10 Bar.
• Figure 6 and Figure 9 show the power supply (only
on some types).
Information about voltage/current is on the sock-
ets,
Figure 6 item A, while the socket, Figure 6 item
B, is 1-phase 220V. All the electrical cables should
be connected to the same power source (to avoid
potential differences). Cables belong to sockets ac-
cording to
Figure 7 and Figure 8 . Tie the cables into
the groove (A) using tie-wraps, Figure 9 item A.
WARNING! Risk of personal injury
• The electrical installation must be done by
an authorized electrician.
• Electrical sockets and cables vary depend-
ing on the type. Pay attention to any na-
tional or local standards.
• The protective bonding circuits' continuity
should be checked after the installation.

5 Maintenance
WARNING! Risk of personal injury
Never carry out any service work, mechanic-
al or electrical, without first disconnecting the
power supply and the compressed air supply.
Inspect the Power Box twice a year as follows:
• Check the bracket/mounting/leakage.
• Check the electrical and compressed air connec-
tions.
• Check the couplings and valves regarding clearance
and wear.
• Check for damage/wear to hoses and cables.
