Note:
1. Customer to specify the exact nominal power supply available at site so that electrical components are selected
accurately.
2. Main power must be supplied from a single field supplied and mounted fused circuit breaker.
3. The compressor crankcase heaters must be energized for hours before the unit is initially started or after a prolonged
power disconnection.
4. All field wining must be in accordance with local standards.
5. Neutral line required on 380V-3Ph-50Hz(5 wires) power supply.
6. Rated load Amps values are on nominal conditions.
7. The ±10% voltage variation from the nominal is allowed for a short time not permanent.
