2-8 Installation
Input Power 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.

Output Wiring 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.
