Connecting Inlet Power, Input and
Output Signals
Model 1092A/B/C Model 1092A/B/C series clocks include an external wall-mount power supply
with an output of +9 VDC at 500 mA. The Model 1092A/B/C has an input voltage range from
+8 to +15 VDC.
Model 1093A/B/C To provide for a wide range of inlet power sources, the 1093B can be ordered
with any one of three different power inlet modules. Each of the power inlet module connectors are
illustrated here and also in Chapter 2. Take time to examine the power inlet module connection
on your clock to verify that it is correct according to your order. Also, carefully check the voltage
range at the inlet connector before connecting power to the clock.

3.1.1 Cordsets and Plug Styles for Option 07
Make sure that the cordset matches the wall connector for your country. Table 3.1 lists IEC-320
mating cordsets by country and include plug style and specifications.
3.1.2 Option 07, Connecting Power to the 1093B
Connect the IEC-320 plug on the cordset to the IEC-320 connector on the 1093B, and then connect
the wall plug on the cordset into the wall socket.
