Hazardous voltages may be present on all output and guard terminals. To prevent electrical
shock that could cause injury or death, never make or break connections to the 2450 while
the output is on.
To prevent electric shock, test connections must be configured such that the user cannot
come in contact with conductors or any device under test (DUT) that is in contact with the
conductors. It is good practice to disconnect power before connecting DUTs. Safe installation
requires proper shields, barriers, and grounding to prevent contact with conductors.
The following figure shows the schematic for the application.
Figure 49: Model 2450 connections to a solar cell
The following figures show the physical connections for the front and rear panels. Note that you must
use either the front-panel terminals or rear-panel terminals — you cannot mix connections.
The rear-panel connections are triaxial. The front-panel connections are safety banana jacks.
Turn the power to the instrument off before attaching connections to the 2450.
