Black flat lacquer per FED-STD-595, Color 37038
6-32 THD inserts 5/32 minimum depth are provided in baseplate. Steel
6-32 bolts American Standard, Unified National Fine Series, slotted

The overvoltage protector should be connected to the Abbott power
module as shown in Figure 1. Use a Bussman Mfg. Co. Type
GBB Tron Rectifier fuse or equivalent with a current rating as
indicated on the power supply identification label.
Setting the Trip-Point Voltage
With an adjustable laboratory power supply adjusted to 0 volts
output, connect the OVP module in the circuit as shown in Figure
II. Select the resistance R, required to limit the current
in this circuit to 0.2 amps at the desired trip-point voltage. Increase
the voltage of the power supply slowly and observe the voltage
reading on the DC volt-meter until the voltage suddenly drops. This
is the trip-point voltage of the OVP module. The trip-point
voltage setting can be increased by adjusting the potentiometer
on the OVP module clockwise, and decreased by adjusting it counterclockwise.
