III — INSTALLATION
MOUNTING POWER SUPPLY.
Refer to Figures 2, 3
and 4. The unit may be mounted on one mounting surface.
The temperature of the air surrounding the power supply
must not exceed the ambient values given in the graph in
Figure 1.
INSULATION.
Install unit at least 0.3 inches (8mm)
away from base with 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 3).
VENTILATION.
It is recommended to keep at least 0.40
inches (10mm) clearance from adjacent equipment for
proper ventilation (see Figure 3).
CONNECTIONS.
Connect a load to the output of the
power supply by connecting pins 5 through 8 (+) of output
connector CP2 to the load (+) terminal, and pins 1 through
4 (–) to the load (–) terminal. See Figure 4 for input/output
connector and pin locations.
When connecting the power supply to the load, keep the
wires as short as possible, and use twisted pairs (use Wire
Size AWG No. 22). Make sure there is only a single ground
point in the load circuit. Capacitors (100UF electrolytic and
0.1UF film) can be placed across the load to filter out
noise.The AC input power is applied via input connector
CP1. Make sure to connect the AC input Neutral and Line
wires to pins 3 and 1, respectively, of CON1. See Figure 5
for mating connector information. A Cable Kit (P/N 219-
0495) is available as an option from Kepco. The kit
includes one input and one output cable (one meter long)
with the mating connectors for Input and Output connectors
at one end and unterminated wires at the other end.
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.
