[RE-wrenches] Radian ROCB in Outback GSLC 120/240 AC

[Drake]

Hello Wrenches,

I'm hooking up a Radian with a Remote Operated Circuit Breaker for AC 
coupling.  With only the positive inverter cable connected, we found 
battery voltage at the negative inverter cable with all switches off. Humm.

It turns out that the Remote Operated Circuit Breaker (ROCB) control 
circuit is the culprit. This is factory connected to the battery side 
of the main breakers in the GS Load Center. The voltage present gave 
my assistant a minor shock when he tried to hook the negative 
inverter cable to the battery.

When the negative battery cable lug touched the negative battery 
terminal, a sound came from somewhere that sounded like a super fast 
relay chatter. One tech support person thought it could be the ROCB 
trying to close, as it was open (off) position. The tech support 
people are only able to speculate about what might be happening.

Another tech support person said that if the factory wiring on the 
relays was correct, it would be impossible to get a shock. Going 
thought the diagram in figure 2 of the attachment, it looks to me 
that voltage would conduct to the negative battery cables if all the 
relay contacts were positioned as shown in figure 2.

Has anyone hooked up the GSLC AC 120/240? Have you had any unusual 
voltages or noises before turning on the main DC breakers? From 
Figure 2, do you think it would be possible to get a complete circuit 
through the relays before the main breaker is turned on?

Thanks,

Drake
