PVP250kW & PVP260kW Inverter

Installation & Operation Manual

B. Set the jumpers for the center inverters on the network.

• J7 - remove all three jumpers from the J7 pins for any inverter in the middle

of the network, and place the jumpers in the J16 neutral position.

C. Set the biasing.

Biasing sets the voltage levels on the data lines of an inactive or idle network.

It is very important that at least one device on the network provides biasing. On

shorter networks with fewer installed devices, biasing may only be needed on

the device furthest away from the master. Longer networks that are terminated

on both ends may require two devices to have their biasing enabled. To use the

inverter’s built-in biasing set the following jumpers:

• J7 - install a jumper on the rst pair of pins labeled “High”.

• J7 - install a jumper on the last pair of pins labeled “Low”.

Alternative: Terminate the network and enable biasing.

If an end inverter on the network requires both termination and biasing to be

enabled, set the following jumpers:

• J7 - install a jumper on the rst pair of pins labeled “High”.

• J7 - install a jumper on the rst pair of pins labeled “Line”.

• J7 - install a jumper on the last pair of pins labeled “Low”.
