The unit is designed for 230 V / 50 Hz single-phase alternating current mains. The cable is not included in the delivery set. Use insulated
cables with the minimum cross-section of 2.5 mm
2
(up to 50 m long) and 4 mm
2
(up to 100 m long).
The cable cross-section is given for reference only. The actual conductor cross-section selection must be based on its type, the maximum
permissible heating, insulation, length and installation method.
The unit is connected to power mains via an automatic circuit breaker with a magnetic trip built into the stationary wiring. The trip current
of the automatic circuit breaker must correspond to the current consumption (see the «Technical data» table on page 6).
Use copper cables only.
All the control and power supply cables must be connected in accordance with the terminal markings while observing proper polarity.
