The catalogues are available and the instructions in this manual. under: None of the operating conditions defined in the https://www.schaltbau.com/en/media-library/ corresponding data sheets and in our catalogues B193 and B294 in section “Specifications“, such as voltages, currents, ambient conditions, etc. may be changed.
Dangers and security measures 3. Dangers and security measures 3.1 Electrical dangers DANGER The contactors are used to switch voltage. The touching of electrically conducting parts may result in serious injuries or even death! Energized parts are all metal parts belonging directly to one of the circuits or wires leading there. All other visible metal parts and wires may also be energized in the case of a failure.
Dangers and security measures 3.3 Measures for avoiding damages and malfunctions NOTICE Aggressive fluids may damage the contactors. Make sure that the contactors are not exposed to aggressive fluids. NOTICE Improper handling of the contactors, e.g. when hitting the floor with some impact, can result in breakage, cracks and deformation.
Notwithstanding its small size, the contactors feature an extraordinary switching capacity. 4.4 Technical information and material The C193 series contactor is suitable for DC applica- specification tions up to 1,000 V. The C294 series contactor is suitable for DC applica-...

► Return shipments Schaltbau recommends to keep the original packing box for any return shipments. If no original packing box is available care must be taken to pack the contactor in a way that prevents damage during shipment.
Schaltbau strongly recommends Schnorr-Washers (or similar) to se- cure the screws. As an alternative, contactors of the C193 series can also be installed by means of DIN rail mounting. Fig. 3: C193 series: Dimensions (in mm) and arrangement of See section “DIN rail mounting (only C193 series)“.
Examples for intended mounting positions (A) and - Socket wrench set, hexagon nuts not permissible mounting positions (B) (the figure shows the C193 series, the intended - Hexagon socket wrench set mounting positions for the C294 series are the same)

Check the pull-in and drop-off voltage according to the requirements of Schaltbau. Refer to cata- logues B193 and B294. Check the laying of cables. Cables must not be squeezed or bent. If applicable bundle and secure with cable ties.
Maintenance 8. Maintenance Note the expert knowledge which is essential for car- rying out maintenance work, mentioned in chapter “2. General and security information”. 8.1 Safety DANGER The contactors are used to switch voltage. The touching of electrically conducting parts may result in serious injuries or even death! Energized parts are all metal parts belonging directly to one of the circuits or wires leading there.
Maintenance Regular check activities All of the maintenance activities that may be carried out on the contactors by skilled personnel are listed below. Component Visual inspection Measures Cables/busbars Check for: In case of faults: broken cables, cable lugs immediately replace damaged cables or cable lugs damaged insulation immediately replace damaged bus-...
