Comments:

a) FG compressors for HST applications make

it obligatory to use the starting capacitor and

must be installed according to figure 38;

b) The FG compressor relay for HST

applications is different from that used in

FF compressors with regard to the following

aspects:

VIVI

• terminals 11 and 13 are longer than normal

to permit capacitor's connection;

• it does not have the copper wire bridge

between terminals 11 and 13.

The compressor, therefore, will only start if

the corresponding capacitor is installed. In

the start relay in figure 37, one power lead

must be connected to the thermal protector

(terminal 3) and the other to terminal 10 of

the relay;

c) the use of a different capacitor from those

recommended in the previous table may

affect the performance of the thermal

protector and cause the motor to burn out.
