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 insula-
tion 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 0.39
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 P3 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.
