Table 5.2 MCC&LRA of low voltage models
Note
：
Cooler standard equipment Motor A, able to operate the maximum load condition is about CT / ET
= 40/13
℃
, the heating machine operating condition is about CT / ET = 52/14
℃
, a slightly different
from the actual horsepower during the motor design. The actual maximum continuous operation
current (MCC) should be in accordance with the above table. When the actual operating conditions
of the unit exceeds the MCC value, please use Motor B and state for Motor B on the purchasing
order instead.
Caution
：
1. This table stated rated current and LRA for Motor design performance are not referring to the
compressor operating rated current.
Caution
：
2. The value of MCC in this table is related to the maximum temperature rise (90 °C) of the Motor
and is irrelevant to motor power (size). Therefore, a voltage drop in the power supply will cause
motor temperature rise (refer to Motor Coil Temperature Sensor Pt100 or Pt100 Description).
5.3.5 Grounding
Grounding point in electric system normally is a neutral point. Exposed compressor
conductor should not be electrified in normal use. But there is possibility that the
compressor is electrified under malfunction condition. For security purpose, HANBELL
strongly recommends to ensure the grounding during installation.
Suggestion:
a. Dedicated M12 grounding screw (instructed in terminal box) should be reliably
connected with grounding wire.
