Installation
Connecting the mains
Chilli Pro 12 & 24 are designed to run on a nominal 230V 50Hz 3-phase supply, with a maximum 100A per phase. However, all variants of Chilli Pro without RCDs can be converted to single phase operation. This results in a total 100A maximum input. A secure mains earth is required. Phase to neutral voltage must not exceed 255V.
The units are supplied with a selection of knockouts on the top of the unit for mains cable entry.
The Chilli Pro 12 has the following knockouts:
- Top 2 x Ø50.0mm,1 x Ø32.0mm
- Bottom 2 x Ø25.5mm
The Chilli Pro 24 has the following knockouts:
- Top 4 x Ø50.0mm, 2 x Ø32.0mm
- Bottom 2 x Ø25.5mm
Appropriate cable glands should be fitted to the knockout holes provided to protect the mains cables from damage.
Ensure that all the mains connections are fully tightened and lock washers are used where supplied.
Mains supply will come in from the top of the dimmer, with phases and neutral being wired to the isolator input terminals. Input terminals will accept a maximum 35mm2 cable.
The Earth should be connected to the main Earth stud on the chassis of the dimmer.
RCD versions of Chilli Pro cannot be operated or powered from a single phase supply.
