Electrical connection (fig. 4a)
Before connecting the device to the mains make sure that:
- the voltage and frequency rated on the data plate conform to those of the mains supply;
- an all pole circuit breaker which leaves at least 3 mm between the contacts has been installed
between the device and the mains;
- the high voltage 230V wires pass through the holes marked "A" and are routed separately
from the low voltage wires which pass through the holes marked "B";
- the wires are fastened down using a cable clamp;
- once the wiring is complete the holes through which the wires have passed have been sealed
using silicon;
- the holes which are not used are blocked by inserting the caps "C".
