V1000 to GA500
Wiring has one change. The SC terminal on the V1000 now moves to the SN terminal on the GA500. It wires the same otherwise.
The GA500 inverter comes with a jumper from SC to SP. Leave this in place. This selects the option for sinking inputs. We use sink as an input type. Before connecting wires to S1 thru S7 you should read 24VDC on S1 to SN.
There is also a jumper from HC to H1 to H2. Leave this in place.
The V1000 has a PC terminal for the common for P1, but the GA500 does not. The GA500 common for P1 moves from PC to C1.
Inverter Fault at Power Up
This is a simple error. When power is removed from the machine, the inverter will throw a
Uv fault stating the inverter has lost power. Previous models of inverter may have had few seconds before this error would appear, but the GA500 and GA800 appear to display this error almost instantly.
The Big Idea, if you power cycle the machine, the inverter may have enough charge to display a
Uv fault. If this fault still exists when machine power is restored, you will see an inverter fault. The error can be cleared by pressing the reset button on the inverter control panel.
