Vsn700 Installation - ABB VSN700 Product Manual

VSN700 installation

1. Check packaging for all components:
2. Determine the indoor location of the VSN700.
3. Mount the data logger. The logger comes with flanges with pre-drilled holes for easy
4. Connect shielded twisted-pair wire to the RS-485 terminals on the inverter(s). If there are
5. For systems with multiple inverters, the RS-485 network must be terminated at the final
In some environments you may experience poor RS-485 signal quality due to noise. If signal quality is a

problem, double-check that the last inverter in the chain is terminated and other inverters are not terminated. If
problems persist, it may prove helpful to attach a 120 Ohm 0.5 Watt resistor across screw terminals 1 and 2 on
the data logger.

optionally ordered with other models. All data logger versions require a weather protected
site. The included power supply requires an ambient temperature between 0

multiple inverters, wire the inverters in a daisy chain configuration. Refer to your inverter
manual for information on terminal locations and daisy chaining inverters. Use RS-485
data wire with one twisted pair, one ground conductor, and a shield with drain wire
(Belden#3106A or equivalent). DO NOT USE CAT5/6 CABLE FOR THE RS-485 DATA
WIRE.
inverter by a switch near the RS-485 terminal block. The farthest inverter in the daisy
chain must be terminated by setting the inverter termination switch to ON. For all other
inverters in the daisy chain, turn OFF the termination switch. Below are pictures of RS-485
terminals in various inverters, as well as locations of the termination switch.
more information, consult your inverter's manual for locating the RS-485 terminals and the
termination resistor switch.
