2 Safety
2.1 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 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.
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 suitable motor protection switch.
2.2 Limits of use of product

4 Installation
4.1 Installing electronic drive unit in control cabinet
NOTICE
Damage caused by overheating
The ambient temperature must not exceed the permissible operating temperature of the device.
►Make sure there is unobstructed circulation of air when installing the device.
►Periodically check and clean the installed air filter, if necessary.
Integration of mounting plate into switchgear
Observe the boundary conditions for the installation:
●DIN EN IEC 61439-1: 2021 (VDE 0660-600-1): Low-voltage switchgear and control-
gear assemblies
Prerequisites
●Adequate space in control cabinet
Installing electronic drive unit

4.3 Connecting temperature sensors and fan
For temperature monitoring, the roots pump has a pre-assembled temperature sensor with cable con-
nection on each of the two oil chambers. The two connecting cables on the fans are routed to the out-
side through openings in the fan hoods.

Connecting extension cable
The sensor and fan cable are safeguarded geometrically against interchanging.
1. Connect the connecting cables of the temperature sensors to the two matching connectors
(Temp. 1 | Temp 2).
2. Connect the connecting cables of both fans to the matching connectors (Fan 1 | Fan 2).
4.4 Implement electrical safety measures
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 suitable motor protection switch.
Installation
7/16

Installing the mains disconnection device
1. The power details for the setting value can be found on the motor rating plate.
2. Install the circuit breaker within reach of the vacuum pump during building installation.
3. Label the circuit breaker as a disconnect device for the vacuum pump.
4.5 Connecting to mains power supply
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
