System Applications and Electrical

The SD(H) compressor unit electrical box major components and electric data for all compressor
sizes are shown in Figure 7.
The SureStart Module is a factory installed component that (1) reduces compressor starting current
and (2) reduces compressor starting torque, thus reducing stress on the compressor at start-up.
The Earth Loop Protection Control System, comprised of the EPS Power Supply, EPS Module and
EPS Fuse is in the contained within the electric box. This system is factory wired and ready to be
connected to the anode wire through an external electrical connection on the backside of the
compressor cabinet. The anode wire connection is detailed in a later section of this manual.
SD(H) Heating and Cooling System electrical and application illustrations are as follows.
