3. Installaon
Refer to the individual pump operang instrucons for installaon informaon.
3.1 Use as a benchtop unit
Figure 3 Benchtop unit
BC-0027-A
Fix the supplied adhesive feet to the power supply unit and place the unit on an even,
level surface.
3.2 Installaon to the pump
1. Aach the bracket to the power supply unit using 6x M4x14 bolts, washers and
spring washers. Tighten with a torque of 3 Nm. Refer to Figure: Mount the bracket
to the power supply.
2. Aach the bracket with the power supply unit to the pump. Refer to Figure: Mount
the bracket to the pump.
▪ If there is no air cooler, aach the bracket using 4x M5x14 bolts, washers and
spring washers and ghten with a torque of 5 Nm.
▪ If the air cooler is mounted, aach the bracket using 4x M5x16 bolts, washers
and spring washers and ghten with a torque of 5 Nm.
3. Insert the connecng cable between the pump and EPS 800.
4. Tighten the cable through the plug at the connecon end.
The unit is not equipped with a mains switch. It will power up aer the mains cable is

4. Operaon
CAUTION: DANGEROUS VOLTAGE
Risk of electric shock and damage to the equipment. The turbomolecular pump and
the EPS 800 must only be operated if installed in compliance with the informaon
provided in the Operang Instrucons.
The disconnecng device must be easily accessible.
4.1 Start up
CAUTION: DANGEROUS VOLTAGE
Risk of electric shock and damage to the equipment. Make sure that the mains power
supply is switched o before you connect or disconnect the mains cable.
The mains power supply must have a suitable earth connecon.
To start the EPS 800 do the steps that follow:
1. Plug in the mains cable.
2. Secure the mains cable so that it cannot be pulled out inadvertently.
To test the connecon, switch the turbomolecular pump on and o. Refer to the
applicable turbomolecular pump operang instrucons for informaon.
The turbomolecular pump will start only when the mains cable is plugged and a start
command is provided.
4.2 Shut down
To shut down the EPS 800 do the steps that follow:
1. Switch o the turbomolecular pump.
2. Wait for the rotor of the pump to stop. The Green status LED will stop ashing to
conrm that the rotor is ideal.
Note:
The rotor can take several minutes to stop. With the DC power supply o, the
turbomolecular pump will act as a generator supplying the frequency converter
with energy as indicated by the yellow power LED.
3. Disconnect the mains plug from the power supply.
In case of an emergency shutdown, disconnect the mains plug.
4.3 Maintenance
The EPS 800 is maintenance free. Repairs must only be done by Edwards.
You must disconnect the mains plug from power supply and make sure that the system is
protected against automac restart during any repair work.
