2.1 Safety precautions
●Observe the safety and accident prevention regulations.
●Check regularly that all safety precautions are being complied with.
●Do not loosen any plug connection during operations.
●Keep leads and cables well away from hot surfaces (> 70 °C).
●Always ensure a safe connection to the protective earthing conductor (PE, protection
class I).
●The unit has been accredited with protection class IP 54. Take necessary measures
when installing into ambient conditions, which afford other protection classes.
●Before carrying out any work disconnect the unit and all associated installations safely
from the mains.
2.2 Protective equipment
Determined situations concerning the handling of vacuum pumps require wearing of per-
sonal protective equipment. The owner, respectively the employer are obligated to pro-
vide adequate equipment to any operating persons.
Duty to inform
Each person involved in the installation or operation of the unit must read and observe
the safety-related parts of these operating instuctions.
The operator is obligated to make operating personnel aware of dangers originating
from the unit or the entire system.
WARNING
Danger of unsafe electrical installation
Safe operation after installation is the responsibility of the operator.
Do not independently modify or change the pump and electrical equipment.
Make sure that the system is integrated in an emergency off safety circuit.
Consult Pfeiffer Vacuum for special requirements.
WARNING
Danger due to lack of power disconnection device
Pump and electronic drive unit are not equipped with a power disconnection device. In-
stallation of a user-supplied power disconnection device in accordance with SEMI-S2.
Fit a circuit breaker with an interruption rating of min. 10,000 A.
WARNING
Danger of electric shock
In case of defect, the parts connected to the mains supply are under voltage.
Always keep the mains connection freely accessible so you can disconnect it at any
time.
CAUTION
Risk of injury through hot surfaces
Vacuum pumps can become hot during operation.
Allow the pump to cool before maintenance and repairs.
If necessary wear protective gloves according to EN 420.

Safety
2.3 Proper use
●Pfeiffer Vacuum power supply units OPS 400 only serve to the integrated voltage sup-
ply of Pfeiffer Vacuum turbopumps.
●Only operate Pfeiffer Vacuum power supply units OPS 400 directly mounted on the
pump.
●Only operate Pfeiffer Vacuum power supplies in the available specification.
2.4 Improper use
Improper use will cause all claims for liability and warranties to be forfeited. Improper use
is defined as usage for purposes deviating from those mentioned above, especially:
●connection to mains supplies, which do not confirm to the regulations IEC 61010 or
IEC 60950
●connection to pumps or units which are not suitable for this purpose according to their
operating instructions
●connection to units which have exposed voltage-carrying parts
●operation of the devices in areas with ionizing radiation
NOTICE
Destruction of the device due to misuse
The use or operation of the power supply OPS separated or dismantled from the tur-
bopump will inevitably lead to its destruction by overheating. The cooling surface of the
power supply must be firmly connected to the bottom part of the turbopump.
Never operate the power supply disconnected from the pump.
When mounting replacement devices, pay attention to a proper connection between
the power supply and the pump.
warranty seal
Closure seal
The product is sealed at the factory. Damaging or removal of a closure seal leads to the
loss of liability and warranty entitlements.
Do not open the product within its warranty period!
For process-related shorter maintenance intervals please contact the Pfeiffer Vacu-
um Service.

3 Product description
3.1 Product identification
Product characteris-
tics The power supply unit OPS 400 forms a single unit with the turbopump and the electronic
drive unit. The power supply is mounted to the pump and connected to the electronic
drive unit ex factory. The valid supply voltage for the power supply amounts 90 - 265
VAC, 50/60 Hz.
OPS power supply units exclusively serve to the integrated voltage supply of Pfeiffer
Vacuum turbopumps featuring electronic drive unit. The output voltage "DC out" is se-
curely separated from the power input voltage "AC in".
To correctly identify the product when communicating with Pfeiffer Vacuum, always have
the information from the rating plate available.

5Operation
5.1 Switching on
Connect the mains cable to the mains.
After the mains voltage is applied, the electronic drive unit performs a self-test to check
the supply voltage. The turbopump is set into operation.
Observe the components operating instructions.
5.2 Switching off
Remove the mains plug from the power supply.
CAUTION
Automatic start
After bridging the contacts Pin 1, 3, 4, 14 on the connection "remote" or using the mating
plug supplied and setting up the supply voltage, the turbopump will run up immediately.
Switch on the mains supply on the turbopump immediately before operation.

Replacing the integrated power supply
6 Replacing the integrated power supply
Basically the exchange of the integrated power supply at all specified types of the pump
is the same. The power supplies OPS 400 are attached to HiPace 300 pumps with an
adapter plate.
6.1 Dismantling
Turn off the vacuum pump, vent to atmospheric pressure and allow to cool, if neces-
sary.
Remove the mains plug from the power supply.
Remove the vacuum pump from the system, if necessary.
Close the flange openings by using the original protective covers.
Turn the turbopump over onto the closed high vacuum flange.
Unscrew the Allen head screws 10e of the fastening of the power supply.
Remove the power supply from the pump.
Unscrew and remove the connecting plug 10.1 from the electronic drive unit.

Particularities in
HiPace 300 The power supply OPS 400 and the bottom part of the HiPace 300 pump with the elec-
tronic drive unit differ in length. This gives two possibilities to fix the power supply flush
to the pump (see figure).
Fig. 7: Positioning of the OPS 400 at HiPace 300
Fix adapter plate to the bottom part of the pump optionally in position "a" or "b".
Screw cable with connecting plug 10.1 to the electronic drive unit (DC in).
Mount OPS 400 to the threaded holes of the adapter plate.
