1.3.1.2 Electrical Heating
TC.ACS power supply systems operate with significant amounts of energy. High currents can cause heating of
cables and wires. In particular, during unmonitored endurance tests insulation fires and short-circuits may be
caused.
• At particular risk are connectors, switchgear and cable terminals. Check these parts particularly carefully and
at regular intervals.
• Use wiring material suitable and stipulated for your application with the related insulation class.
• Monitor your system actively or passively using appropriate sensors or by monitoring parameters.
1.3.1.3 Arcing and sparking on opening Contacts
Note that on opening a circuit through which a current is flowing, arcing with very high energies can be produced
depending on the inductance!
In some circumstances this arcing can result in burns, damage to the eyes as well as damage, destruction or fire
on parts of the system. The usage of appropriate DC contactors as isolating devices in DC circuits is
recommended! In case of doubt contact the related manufacturer. Take into consideration that the protective
devices on the TC.ACS system cannot detect an arc as a fault condition, as this situation may be a required
function.
1.3.1.4 Mechanical Injury
As on all electrical installations, mechanical injuries to the head and hands may be caused on removing and fitting
covers, wire and cable connections. Always use the correct tool. If necessary protect the head and hands against
injuries due to cuts and impacts.
1.3.1.5 Chemical Injury
While handling with cooling liquid, open doors and windows and ensure the room is well ventilated also on the
ground level. Avoid work which leads to the formation of aerosols. Use, if necessary the personal safety
equipment:
• Use the respiratory protection at short time and existing low concentrations of vapor and aerosols. Use
breathing apparatus with independent air supply at long time and high concentrations of vapor and aerosols.
• Use protective gloves which are resistant against acids and solvents and safety gloves to avoid direct skin con
-
tact.
