10.4 MOTOR PROTECTION
Compressors are protected against overheating by the conventional inherent internal line break motor
protection, mounted on the motor windings.
The OLP (Overload protector) detects unusual motor temperature rise and/or abnormal high current
input. The OLP trip is influenced by several factors - working conditions, suction gas density/
temperature, supply voltage, etc.
10.5 DEGREE OF PROTECTION
The degree of protection provided by the terminal cover and CSR box supplied with the compressor is IP21, where:
2 – protected against solid objects over 12.5 mm (fingers or similar)
1 – protected against vertically falling drops of water or condensation
