DS-100C Operating Manual IVPC Installation & Quick-Start page 3
• Do not connect the DS-Tracer to a PV system with an open-circuit voltage greater
than 600 Volts.
• Do not connect the DS-Tracer to any PV system with a short-circuit current
greater than maximum for your unit (100 Amperes for a standard DS-100C).
The DS-Tracer RS-232 and USB ports, irradiance inputs, temperature inputs,
auxiliary analog inputs, and auxiliary charge inputs are all referenced to the
same electrical common inside the tracer. Therefore these devices must be
either electrically floating or referenced to the same electrical common.
However, all of these connections are electrically isolated from the PV inputs.
Connecting Your Computer to the DS-Tracer
The DS-100C IV Tracer provides two interfaces; an RS-232 and USB port. The
RS-232 interface uses a standard female, 9 pin connector as shown in Figure 8.
The standard USB connection is labeled “Main USB.” Either of these
connections may be used depending on the configuration of the computer
running the IVPC program. Though, only one of these ports should be connected
at a time.
Note: Special USB drivers must be installed on the computer in order to use the
USB port. See the section Appendix C DS-100 USB Drivers for details on
installing these drivers.
Connecting a PV Module to the DS-Tracer
The DS-Tracer is connected to the PV array or module with the test leads
provided. Before connecting a PV module, be sure the DS-Tracer power switch
is ON and the DISCONNECT switch is in the OFF position. Plug the test lead
into the DS-Tracer being sure to match the red and black connectors. The
Voltage Sense connector is keyed and can only be inserted in one way.
For safety, it is recommended that connections be made to a circuit that can
be isolated from the PV array with a system switch rated at full PV power.
Refer to section 2.0 Panel Layout for details.
