Indicates technical features and methods SCHALTBAU GmbH cannot be held liable for damage to simplify working or indicates informa- caused by non- or only partial observation of the man- tion of particular importance. -
Page 5: Duties Of The Operating Company
Due to their unique features they can also be used C320 catalogue is available under: in a wide range of industrial applications. https://www.schaltbau.com/media/C320_en.pdf The contactors must only be used under operat- ing conditions according to the technical specifi- cations and the instructions in this manual. -
Page 6: Hazards And Safety Precautions
Hazards and safety precautions 3. Hazards and safety precautions 3.1 Electrical hazards DANGER The contactors are used for high voltage switching. Contact with live electrical parts can result in serious injuries or even death! Live parts are all metal parts belonging directly to one of the circuits or wires connecting to them. All other visible metal parts and wiring may also be live if a fault exists. -
Page 7: Measures For Avoiding Damage And Malfunctions
Hazards and safety precautions 3.3 Measures for avoiding damage and malfunctions ATTENTION Aggressive liquids may damage the contactors. Ensure the contactors do not come into contact with corrosive liquids. ATTENTION Improper handling of the contactors, e.g. dropping on the floor, can result in breaks, cracks and deformation. Ensure the contactors are always handled correctly. -
Page 8: Product Information
The C320 catalogue is available under: the event of a fault in the system. Typical applications https://www.schaltbau.com/media/C320_en.pdf are the use as main contactor in battery management systems of high-voltage vehicle batteries, in charging stations for e-mobility, in battery test benches but also in the DC circuits of inverters of photovoltaic systems. -

Page 11: Storage
Store the device in its original packaging, Store the device in a dry and dust-free location. Return shipments Schaltbau recommends retaining the original packag- ing for any return shipments. If the original packaging is not available, care must be taken to pack the contactor in a way that prevents dam- age during shipment. -
Page 12: Installation
- To secure the mounting screws so that they do not come loose, appropriate screw locking elements must be provided. Schaltbau recom- mends using Schnorr washers (or similar). - The mounting screws must be equipped with washers (resting on the device). Installation without washers is not permitted! 99.2... -
Page 13: Mounting Positions
Installation Mounting positions Minimum clearances for type C320K contactors A minimum clearance from magnetic or magnetised The contactors are designed for horizontal or vertical parts is required on all sides and above for type C320K mounting. Examples of correct mounting positions are contactors. -

Installation Safety DANGER The contactors are used for high voltage switching. Contact with live electrical parts can result in serious injuries or even death! Live parts are all metal parts belonging directly to one of the circuits or wires connecting to them. All other visible metal parts and wiring may also be live if a fault exists. -
Page 17: Connecting The S870 Auxiliary Switches
Installation Connecting the S870 auxiliary switches The control wires for the auxiliary switches must be fit- ted with flat receptacles (6.3 x 0.8 mm). ATTENTION The maximum permissible conductor cross- 6.3 x 0.8 mm 6.3 x 0.8 mm section of the auxiliary contact control wires is 1.5 mm / AWG 16 stranded wire. -
Page 18: Connecting The Coil
Installation Connecting the coil A cage clamp terminal block is provided for the coil control wires. The control wires for the coil connection must be stripped accordingly (if necessary, fit with ap- propriate wire end sleeves): - conductor cross-section 0.5 ... 1.5 mm with sleeve 0.5 ... -

Page 21: Checks
Switch the contactor several times without acti- vating the main power circuit. Check the pull-in and drop-off voltage based on the Schaltbau specifications. See C320 catalogue. Check the routing of the wiring. Wires must not be squeezed or bent. If applicable bundle and secure wires using cable ties. -
Page 22: Maintenance
The presence of a voltage-free state can only be clearly identified by a qualified electrician. When the work has been concluded, follow the procedure in reverse. 8.2 Preventive maintenance Contactors of the C320 series are maintenance-free Extraordinary checks need only be carried out if there within the rated mechanical life time. The electrical life... -
Page 23: Regular Tests/Checks
Maintenance ATTENTION Detent-edged rings and detent-edged washers have a limited life time. After screws secured with detent- edged rings or detent-edged washers have been undone three times, the rings or washers must be replaced by new ones. Record the frequency of undoing of the screws in the work log. -
