- Installations need to be undertaken by a qualified electrician, preferably with experience working with large generator sets which is a requirement for insurance and for generator warranty purposes.
- Bonded neutral earthing has to be done according to the applicable South African regulations between the generator, ATS and mains incoming supply.
- Communications cable must be of the shielded type to avoid harmonic interference.
- Surge protection is recommended to be installed on the mains incoming feed to avoid the damage of equipment through over voltage, as well as in the situation when an Automatic Transfer Switch (ATS) is used, as the ATS is setup to sense voltage dips which switches the ATS.
- The copper cable used must have a cross-diagonal section large enough to handle the amount of current without overheating up as per the South African regulations.
- An important point is to confirm the phase rotation is checked during the installation as this will determine the direction in of equipment.
- A Certificate of Compliance (COC) needs to be issued by the electrician after installation has been completed for the handover of the generator.
- The generator must be placed on a surface that will be level and be able to handle the impact of the weight over time, as well as for fuels and oils to be level.
A reinforced concrete slab is recommended especially for large generators.
