Unscrew ground conductor and unplug display cable then set door aside.

To install the battery modules, place the battery in the enclosure then slide the brackets inward on each side of the battery and tighten the wingnut to secure. Repeat for batteries 2 and 3. The battery module serial numbers will be needed for the commissioning. These are labeled on the module and the box they shipped in.

Connecting the Batteries

For wiring the upper battery, locate the cables labeled for the upper battery module. Connect the PCS cable to the battery terminal labeled PCS. Connect the upper battery link-out cable to the battery port labeled link-out. Connect the

• plug to the red battery terminal labeled +. Connect the – plug to the black battery terminal labeled -.

For wiring the lower batteries, locate the cables labeled for the lower battery modules. Connect provided lower inner battery link-out cable in the COM port in the battery expansion wirebox (12).

For battery expansion – Parallel Connection, connect the outer battery to the upper battery and click. Connect the inner battery to the outer battery and click. Repeat for additional batteries.

2. Place the battery in the enclosure then slide the brackets inward on each side of the battery and tighten the wingnut to secure.
3. Repeat for batteries 2 and 3.

Connecting the Batteries

Wiring the upper battery

CAUTION – Do not reverse positive and negative of the battery input terminal. Note – The battery conductors and communications cables are labeled and located inside the enclosure. CAREFULLY cut cable ties and connect as shown. When properly installed a click will be heard.

Upper battery connections

1. Locate the cables labeled for the upper battery module.
2. Connect the PCS cable to the battery terminal labeled PCS.
3. Connect the upper battery link-out cable to the battery port labeled link-out.
4. Connect the + plug to the red battery terminal labeled +.
5. Connect the – plug to the black battery terminal labeled -.

Wiring the lower batteries

CAUTION – Do not reverse positive and negative of the battery input terminal.

Note – IF INSTALLING ONLY ONE BATTERY ENCLOSURE, A terminating cap is required in the COM port in the battery expansion wirebox (12).

Lower battery connections

1. Locate the cables labeled for the lower battery modules.
2. Connect provided lower inner battery link-out cable (loose cable) to the lower inner battery terminal labeled link-out.
3. Connect the opposite end of the lower inner battery link-out cable from step 2 to the link-in terminal on the lower outer battery.
4. Connect the lower inner battery link-in cable to the lower inner battery link-in terminal.
5. Connect the lower inner battery + plug to the lower inner battery red terminal labeled +.
6. Connect the lower inner battery – plug to the lower inner battery black terminal labeled -.
7. Connect the lower outer battery + plug to the lower outer battery red terminal labeled +.
8. Connect the lower outer battery – plug to the lower outer battery black terminal labeled -.
9. Connect the outer lower battery link-out cable to the link-out terminal on the lower outer battery.
10. Insert terminating cap in the CAN/COM terminal in the battery expansion wiring box.

Battery expansion – Parallel Connection

Note – This section applies to systems with multiple battery enclosures. The battery expansion cables/conductors should not exceed 6ft-7in. If installing only one enclosure, skip this step.

Wiring the battery modules (Battery enclosure 2)
If installing a second EI Battery enclosure complete the power, Link-In and Link-Out connections as described in the previous section.

EI Battery enclosure 1
Insert terminating cap in the Link-in terminal of battery module 1 (upper module/enclosure 1).

EI Battery enclosure 2
The terminating cap is inserted in the CAN/COM terminal in the Battery expansion wire box (12).

Note – In the next section, Wiring the EI Battery – Battery expansion, a communication cable is routed between the two enclosures. At the second enclosure this cable will terminate at the Link-in terminal of battery module 4 (upper module/enclosure 2).

Battery expansion – Series Connection

Note – This section applies to systems with multiple battery enclosures. The battery expansion cables/conductors should not exceed 6ft-7in. If installing only one enclosure, skip this step.

1. Using a Philips screwdriver, loosen 2 captive screws on the expansion wirebox (12) on the right side of each enclosure.
2. Install 2 conduits from the right side of enclosure 1 to the right side of enclosure 2 for the DC conductors and communication cable. Use appropriate conduit fittings to provide a water-tight seal.
3. Prepare 2 DC conductors 6AWG and route through the conduit and one CAT5/6 with RJ45 connectors on each end.
4. Connect BAT-Expansion + from enclosure 1 to BAT-Expansion + of enclosure 2.
5. Connection BAT-Expansion – from enclosure 1 to BAT-Expansion – of enclosure 2.
6. Connect a communication cable from the Link Out port of Battery 3 (enclosure 1) to the Link In port of Battery 4 (enclosure 2).
7. Plug terminating cap into the COM port of enclosure 2.

GEC/Bonding terminal

If an external bonding point or grounding electrode conductor is required, these may be connected to right side of the enclosure at the GEC/Bonding terminal. This is not required for the operation of the equipment.

Connecting the inverter

CAUTION – Risk of electric shock! Ensure the inverter and battery cabinet are completely powered off when these steps take place. Make sure to connect the battery inverter first and then connect the communications cable to the inverter.

Note – This section corresponds to section 3.7 and 4.2 in the EI Inverter Quick Start Guide.
Reference that document by scanning the QR code.

1. Loosen the two captive screws on the left side of the battery enclosure’s inverter connection wirebox (8).
2. Remove the two waterproof knockouts (5), (7) at the bottom of the left side of the enclosure. Connect two conduits from the battery enclosure to the inverter. Use appropriate water-tight fittings.
3. Prepare two conductors, 10-8AWG with wire ferrules and route through the conduit.
4. Verify the BAT-switch is in the OFF position, and connect the conductors as follows:
5. Insert the battery conductors into the terminals of BAT+ and BAT- (EI Inverter Quick Start Guide 3.7).
6. Insert the RJ45-CAT5/6 communications cable into the INV terminal (EI Inverter Quick Start Guide 4.2).
7. Once complete, replace the wirebox covers and the enclosure cover by reversing the steps of section 2.4
