BEFORE MAKING ANY CONNECTIONS, MAKE THE POWER SWITCH IS OFF.
DC Input Connection
Before making any connections, prepare a circuit breaker or fuse-protected power DC source
with a suitable rating for operation. See Specications for more details.
Two Phoenix VDFK Block Terminals are provided as DC Input Connections.
• The positive DC Input connection is the RED Terminal Block. Connect it to the positive
terminal of the DC Power Source using an appropriate gauge RED wire
• The negative DC Input connection is the BLACK Terminal Block. Connect it to the positive
terminal of the DC Power Source using an appropriate gauge BLACK wire
RECOMMENDATION: Use the largest gauge (AWG 1/0) recommended) and shortest
length of welding wire possible.
The biggest effect on Inverter performance and EMI is the length and gauge of the DC Input
connections.
CAUTION: Ensure the wiring to this connection butts up tightly against the connector.
To reduce the risk of electric shock, there should be no non-insulated wire exposed.
CAUTION: Do not reverse connect the input wires.
This will cause serious damage to the Inverter and will not be covered under warranty.
