The project in context
Technology in its operating context.
The package was intended for agitator drives specified at 0.12 kW and 230 V AC. The supply combined control components with cables and the mechanical parts of the electrical connections.
Scope of work
- 6 variable-frequency drives for agitators
- 6 Ex de potentiometers with IP65 protection
- 6 sets of connection studs
- Shielded YSLYCY 4 × 1 mm² and LiYCY 2 × 0.5 mm² cables
Execution
Six of each main control component and six connection sets were supplied in 2023. The cable package distinguished between motor and control connections.
Control and local adjustment
Six variable-frequency drives were complemented by six 4.7 kΩ potentiometers with Ex de execution and IP65 protection. The supply specification required ATEX documentation for these potentiometers.
- Components for 0.12 kW / 230 V AC drives.
- The quantities of drives and potentiometers corresponded to six drive assemblies.
Motor and control connections
Shielded YSLYCY 4 × 1 mm² cable was supplied for the motors, and shielded LiYCY 2 × 0.5 mm² cable for the control connections. Both cable items were supplied as six pieces.
Six stud sets completed the mechanical connection to the agitator terminal boxes. The reference covers supply of these parts for subsequent wiring.
Outcome
An electrical-component and accessory package for six agitator drives.
