Hello Wrenches,<br><br>
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. <br><br>
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. <br><br>
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.<br><br>
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. <br><br>
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? <br><br>
Thanks,<br><br>
