Power wiring enters the case through a gland fitting at the lower right
of the unit and connects to a screw terminal block mounted on the
right side of the case. Wiring of this terminal block is shown in
Figure 2-10 below. The voltage and frequency rating and tolerances,
as well as fusing data, are listed on the bottom of the unit.

The benchtop outputs are connected to removable terminal blocks on
the rear panel. Figure 2-5 on page 2-5 shows the location of the
benchtop terminal blocks and Figure 2-11 below shows the Slot A
connections.
The Wall-Mount Optica input/output terminal blocks are located
inside the front door as shown in Figure 2-8 on page 2-7. Cabling is
brought in through the gland on the bottom of the unit and wired to
the terminal blocks shown in Figure 2-11 below.
Note: Output programming is described in Chapters 4, 5 and 6.
