ment.
2.2 Safety instructions
All safety instructions in this document are based on the results of the risk assessment carried out in
accordance with Low Voltage Directive 2014/35/EU. Where applicable, all life cycle phases of the prod-
uct were taken into account.
Risks during installation
DANGER
Danger to life from electric shock
Touching exposed and voltage-bearing elements causes an electric shock. Improper connection of
the mains supply leads to the risk of touchable live housing parts. There is a risk to life.
►Before the installation, check that the connection leads are voltage-free.
►Make sure that electrical installations are only carried out by qualified electricians.
►Provide adequate grounding for the device.
►After connection work, carry out an earthed conductor check.
WARNING
Risk of danger to life through missing mains disconnection device
The vacuum pump and electronic drive unit are not equipped with a mains disconnection device
(mains switch).
►Install a mains disconnection device according to SEMI-S2.
►Install a circuit breaker with an interruption rating of at least 10,000 A.
Safety
10/56

WARNING
Risk of fatal injury due to electric shock on account of incorrect installation
The device's power supply uses life-threatening voltages. Unsafe or improper installation can lead to
life-threatening situations from electric shocks obtained from working with or on the unit.
►Ensure safe integration into an emergency off safety circuit.
►Do not carry out your own conversions or modifications on the unit.
Risks during operation
WARNING
Danger to life from electric shock in the event of a fault
In the event of a fault, devices connected to the mains may be live. There is a danger to life from
electric shock when making contact with live components.
►Always keep the mains connection freely accessible so you can disconnect it at any time.
Risks during maintenance
WARNING
Danger to life from electric shock during maintenance and service work
The device is only completely de-energized when the mains plug has been disconnected and the
vacuum pump is at a standstill. There is a danger to life from electric shock when making contact with
live components.
►Before performing all work, switch off the main switch.
►Wait until the vacuum pump comes to a standstill (rotation speed =0).
►Disconnect all connection cables.
►Remove the mains plug from the device.
►Secure the device against unintentional restarting.
Risks during troubleshooting
WARNING
Danger to life from electric shock in the event of a fault

4.4 Connection diagram
DANGER
Danger to life from electric shock
When establishing the voltages that exceed the specified safety extra-low voltage (according to IEC
60449 and VDE 0100), the insulating measures will be destroyed. There is a danger to life from elec-
tric shock at the communication interfaces.
►Connect only suitable devices to the bus system.
WARNING
Risk of injury due to incorrect installation
Dangerous situations may arise from unsafe or incorrect installation.
►Do not carry out your own conversions or modifications on the unit.
►Ensure the integration into an Emergency Off safety circuit.
Contact load for the accessory connections to "accessory"
1. Note the maximum contact load of 200 mA per connection.
2. However, do not exceed the total sum of the load of all connections of 450 mA.
Potential-free connections
●All inputs and outputs of the "REMOTE" and "RS-485" connections are galvanically
separate from the mains voltage and from the signals on the pump plug.
●The contacts of relays 1 and 2 are potential-free.

4.6 "REMOTE" connection
The 26-pin D-sub connection with the "REMOTE" designation offers the possibility to operate the elec-
tronic drive unit via remote control. The accessible individual functions are mapped to "PLC levels". The
following specifications are the factory settings for the electronic drive unit. They can be configured with
the Pfeiffer Vacuum parameter set.
Required tools
●Calibrated torque wrench
●Hexagon socket wrench, SW 4,5
Input signals Output signals
● High level: +13 to +33 VDC
● PLC Low level: -33 to +7 VDC
● High level: +20 to +28 VDC
● PLC Low level: 0 to +3 VDC
Tbl. 8: Logic levels of digital inputs and outputs
Connecting remote control to "REMOTE"
►Remove the remote plug from the electronic drive unit and connect a remote control.
►Utilize the screened plug and cable.
►Secure the remote control to the "REMOTE" connection.
–Tightening torque of the spacer bolt of the D-sub socket: 0.25 - 0.3 Nm
