4.4 Electrical Installation
4.4.1 Safety Advice
DANGER
Electric shock!
Avoidance:
- The electrical installation is to be undertaken by personnel with electrical training.
- Never connect or disconnect electrical connections while they are live.
- After switching off the system, wait 5 minutes before working on it! In the devices built-in
dangerous voltages may be present after switching off the mains voltage, as well as in case
of loads that store energy.
- The system must be electrically isolated and secured against being switched on.
- Use cables carrying high currents with adequate cable cross-section area (refer to your
national standards and the information on the type plates).
- Your mains voltage must equal the nominal voltage of the system (given on the type plate).
- Output bus bars must be protected against touching (e.g. by fitting a suitable housing).
- After the installation, check the cables for firm fixing.
- The highest permissible unaffected short-circuit (i.e. 10 kA) as well as the smallest required
unaffected short-circuit current (i.e. 1 kA) for each input port of the TC device must be
considered.
WARNING
Electric shock!
Avoidance:
For secure grounding the device must be connected to a grounding network of type TN.
TT- or IT-systems are not permitted.
CAUTION
Possible damage to the device!
- Due to conductive aggressive substances in the installation location
- Due to a larger amount of moisture in the installation location
- Due to foreign objects within the system
Avoidance:
- If necessary, clean the installation location of aggressive substances or moisture using
cloths.
- Remove foreign objects such as drilling sward or screws from the system before you fit new
devices
If you want to use a residual current device, please consider the varying requirements for
protection against fire and the protection of individuals. Regatron recommends the usage of a
residual current device sensitive to AC and DC leakage currents. If such a device is to be
installed, a Type B or Type B+ must be chosen in order to avoid false tripping or lack of
appropriate protection. A type B RCD allows both for processing AC/DC fault currents as also
for considerations of HF components up to the kHz range with up-weighted levels for HF.
The TC device has protection class I according to EN61140.
Prior to the electrical installation, Regatron recommends to confirm the following aspects:
- The type plate matches the data in the order and delivery documents.
- The device nominal data are suitable for the intended application.
- The supplied cables/connectors match the intended connections.
