III — INSTALLATION

MOUNTING POWER SUPPLY.

Refer to Figures 2

and 4. The unit may be mounted on one mounting

surface. The air surrounding the power supply must

not exceed the ambient values given in the graph in

Figure 1.

INSULATION.

Install unit 0.3 inches (8mm) away

from base with the use of 0.24 inch (6mm) diameter

spacers attached to the PC board. Keep at least 0.16

inches (4mm) spacing around and above the unit to

comply with insulation and safety requirements. An

insulator must be used if the spacing is less than 0.16

inches (4mm) (see Figure 2).

VENTILATION.

It is recommended to keep at least 0.40

inches (10mm) clearance from adjacent equipment for

proper ventilation.

CONNECTIONS.

Connect the load to the power supply

by connecting the two (+) output wires from terminal block

TB2 to the load (+) terminal, and the two (–) output wires

from TB2 to the load (–) terminal. The AC input power is

applied via the terminal block TB1. Make sure to connect

the AC input Neutral and Line wires to the P2 and P1 pins

respectively of TB1 (see Figure 3). A Cable Kit (P/N 219-

0406) is available as an option from Kepco (see Figures 3

and 5). The kit includes an input cable, terminated on one

end with an input mating connector; and an output cable,

terminated on one end with an output mating connector.

IV — OPERATION

PROTECTION DIODE: When a number of power sup-

plies are operating in series, the current rating is to be lim-

ited to the rating of the power supply with the lowest rating.
A diode (Vr>2 Vo, If>2Io, Vf<< low) must be connected to
the power supply output terminals to protect the unit from

reverse voltage.
