BATTERY BACKUP
The battery backup is used only for date and time retention
during power interruption. All setpoints and other critical in-
formation are saved on EEPROM chips.
NOTE: It is not necessary to disconnect the battery
backup during extended downtime.
NOTE: The microprocessor will not operate without U24
and U35 EPROM chips installed. When U24 and U35
EPROM chips are not installed, the screen will display:
System Board Initialized
No boot device available,
Press enter to continue.
switch in the starter package as this would bypass the
compressor safety devices.
7. The compressor motor Current Transformer (CT) is installed
on any one phase of the compressor leads.
NOTE: The CT must see all the current of any one phase,
therefore in wye-delta applications BOTH leads of any
one phase must pass through the CT.
CURRENT TRANSFORMER (CT) RATIOS
The CT ratio for various motor sizes (with a 5 amp second-
ary) is given in the following table:

MINIMUM BURDEN RATINGS
The following table gives the minimum CT burden ratings.
This is a function of the distance between the motor starting
package and the compressor unit.

CONTROL POWER REGULATOR
Compressor units that will be used in areas that suffer brown-
outs and other significant power fluctuations can be supplied
with a control power regulator. See the following illustration,
