Mechanical damage
Incorrect operation of the systems can result in mechanical damage to
the downstream equipment and systems.
In particular, on the supply of power to drives it is to be ensured that ex-
cessively high speeds cannot result on load shedding.
The monitoring of the maximum speed with intervention in the safety
chain is recommended above all if the system runs unmonitored.
Handling stores containing large amounts of energy
Modern energy storage systems are able to absorb very large amounts
of energy. This situation has the following consequences:
The cabling should not just comply with the maximum charging
and discharging currents to be expected, to some extent signifi-
cantly higher peak currents are to be expected during switching
processes.
Unlike the TopCon low-voltage system, which is fully current-
limited, in the case of stores containing large amounts of energy
a short-circuit or failure can be very serious. Due to the high cur-
rents serious injuries and serious damage can be caused.
The following, incomplete list indicates some this damage:
1. Burning of wires and connectors
2. Sparking
3. Fires, insulation fires
4. Arcing, welding
5. Electric shocks
Note the following points:
1. Never short-circuit energy stores to discharge them!
Always use a suitable discharge resistor of appropriate power
rating!
2. Visibly secure a discharged energy store using a short-circuit
bridge.
3. Always monitor the maximum storage voltage, also during prac-
tical test operation.
4. Use a device that clearly indicates the charge state of the energy
store, e.g. by monitoring the low-voltage limit.
