Connecting Inlet Power
To cover a wide range of inlet power sources, the 1094B can be ordered with any one of three
different power inlet modules. Each of the power inlet module connectors is 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, make sure to check the inlet module for polarity
and voltage marking before connecting power to the clock.
