(AWG #4). Set Screw
M-8. This is internally connected to the metal chassis of the unit
6. RJ-45 Jack (marked "Battery Temp. Sensor") is used for 2 functions as follows:
a. For input from Temperature Sensor "EVO-BCTS" for temperature compensation when Battery
Type 0 = Lead Acid is selected or,
b. For input for contact closure / opening signal from the Battery Management System (BMS) to Pins 4
and 5 of the Jack when Battery Type 1 = Lithium is selected. When pins 4 and 5 are shorted due to
contact closure, charging will stop in "Charging" Mode and inverting will stop in "Inverting" Mode
The following DC side connections are required to be made (see Fig 3.8):
–
Deep cycle batteries are connected to the battery input terminals (1) and (2). The terminals
are provided with protective covers – RED for Positive and BLACK for Negative. Fit these
covers once connections have been made. For details on sizing and charging of batteries,
please refer to Section 1.4 under "General Information-Lead Acid Batteries".
–
Use appropriate external fuse (Refer to Table 3.1) within 7” of battery Positive terminal.
–
External charging source, if any, is connected to the connectors (3) and (4) as shown
above.
The maximum capacity of the external charging source is 50A.
–
Battery Temperature Sensor EVO-BCTS is connected to the RJ-45 Jack (6). See Fig 2.5 (a)
and 2.5 (b) for details.
–
DC Side Grounding Connector (5) is connected to the Earth ground / vehicle chassis
ground as follows using minimum AWG #6 wire size:
(i) to the Bus Bar "G-B" of the DC Electrical Panel (Fig 3.12)
(ii) to the Bus Bar "G-B" of the Grid Electrical Panel (Fig 3.13)
(iii) to the RV chassis ground in RV (Figs 3.14 and 3.15)
