ELECTRICAL CONNECTIONS

Have the installer of the general power supply install an electrical box with a two-
pole differential 6 Ka - 30 mA 16 A magnetothermal switch and a power indica-
tor.
After checking that the magnetothermal switch is off, connect a mm
2
for the power supply and a mm 2x1.5 cable for remote control through the deri-
vation box.
Refer to the wiring diagrams provided with this manual for instructions on how to
connect them with the terminal board in the unit. Make sure there is a ground con-
nection.
Once the connections have been made, assembled the covers using the screws
provided, positioning the cover with the handle on the front side, the side closest
to the operating area. Then insert the two-way coupling into the suction connec-
tion (11).
Finally, assemble the tool holder support (19), if provided.
If the unit is mounted suspended from an adjustable arm, use the cables in the
arm. If the unit is mounted differently, the installer must provide the cables.
N.B. The materials required for electrical connections are not supplied with the
unit, but must be provided by the installer of the power supply. Electrical connec-
tions must be made by trained electricians.
PNEUMATIC CONNECTIONS
Install a 3/8 air treatment unit (18) with a central connection for dry air upstream
of the unit, connecting it with two air hoses, Ø 6 x 14 (25) for dry air and 10 x 19
(24) for lubricated air, as shown in Fig. 1.
Now connect the two hoses protruding from the connection tube as follows:
- connect the Ø 10 x 19 hose to the hose connection Ø 12 (9), which supplies the
two couplings for pneumatic tools;
- connect the Ø 6 x 14 hose to the hose connection Ø 7 (10), which supplies the
utility air coupling.
Both hoses must be fastened in position using the clamps provided.
Refer to the pneumatic diagram provided with this manual illustrating connections
specific to each model.
START-UP
Minimum power supply requisites and connections:
Electric mains
- Single phase 110/230 V line with a ground wire of adequate section;
- a 16 A 6Ka - 30 mA differential magnetothermal switch should be installed
upstream of the power outlet.
Compressed air mains
- Maximum operating pressure: 8 bar;
- must supply adequately filtered dehumidified air.
OPERATING INSTRUCTIONS
Electrical tool connections
- Insert the tool's plug into the socket on the unit;
- if the tool is equipped with a vacuum device, connect it to the 2-way link using
the sleeve;
- do not connect tools with loads over their rated capacity
electrical sockets.

TROUBLESHOOTING

EFFECTS
The unit does not start up the suction system
The suction system does not
start up automatically
Insufficient suction capacity
No compressed air supply
to rapid couplings
When the pressure control is adjusted,
there is no change shown on the
pressure gauge
When both pneumatic tools
are connected the power level drops
Pneumatic tool connections
- Connect the compressed air hose to the rapid fitting on the unit; connect the
other end to the tool;
- if the tool is equipped with a vacuum device, connect it to the 2-way link using
the sleeve (optional).
2 3x2.5 cable
Preliminary checks
- Check that the dust bag is in the container and that the filter is assembled on the
head;
- check that the vacuum hose is properly fixed and does not hinder tool move-
ment;
- check that there are not leaks from the compressed air supply system.
Only after having performed connections should you proceed with a brief operating
trial of the tools following their instructions.
UNIT USE
Manual operations
The machine operates in manual mode: turn the switch (21) to start the dust
vacuum turbine.
Automatic operations
EP3A and EP3C are equipped with sensor for automatic operations: the turbine
automatically starts when the electric or pneumatic tool is turned on. When fini-
shed, turn the tool off and the turbine will stop automatically after 1 minute.
Additionally, unit versions "C" are equipped with an automatic vacuum flow cut-
off system (CUT-OFF).
MAINTENANCE
The manufacturer or an authorised representative must carry out a technical ope-
rating inspection of the machine controls and check for any damage to the machi-
ne's filtering system at least once a year. RUPES Spa is not liable for any direct
or indirect damages due to failure to comply with the instructions provided in this
manual.
ORDINARY MAINTENANCE (to be performed by the user)
- inspect compressed air supply hoses and connections;
- inspect dust suction hoses.
EXTRAORDINARY MAINTENANCE (to be performed by the service centre)
- Periodically inspect the electric wires and plugs. If they are faulty or worn, repla-
ce them;
- periodically inspect the compressed air hoses and connections.

CAUSE
Power off
Faulty power supply cable or commutator
Faulty electronic module
or micro-switch
Suction system - Dust bag is overfull
There is an obstruction in one
of the hoses or accessories
Compressed air supply is not connected properly
Faulty control, or leakage from
compressed air supply
Insufficient air flow
