Is that little 85,86,87,30 ice cube relay rated for the pack voltage? Is a fuse needed in the wire coming off 87?

Where is the B+ terminal? How does the Pack get charged--does it require that the main switch is ON? If so how is that done?

The little wires coming off of the Main Contactor are confusing--are those 12V for the coil or HV?

The high Voltage Contactor (GV200PA-1) is activated by the by 12 volt relay (ice cube thing), via lines X1 & x2 (small wires). X1 is Positive (+) & X2 is Negative (-). Both are 12 volts. Yes it is a high voltage relay.
Current Rating: 30 Amps AC/DC
Voltage Rating: 240 Volts AC
85 is negative ground. 86 is, key switch in, that activates the relay (coil). 30 is the common (power) in. 87 is the source out (fan, pump, ect.) in this case it is line #24 of the motor controller. There will also be a line, #26, which is a contactor return, from the controller, that will connect to the ground (relay 85 and GV200PA, X2 (-) line).

+B (high voltage) and +B precharge send current to the controller. The +B precharge is activated when the key switch is turned on through the relay. Once the Contactor is engaged via the 12 volts, +B high voltage is activated by turning on the emergency Gigavac switch.
