Before removing the circuit breaker panel, knock off the cover on the CIM indicator hole on the panel. • If battery cabinets are combined, remove the side panels between battery cabinets. • If the battery string is configured with the neutral wire, measure the currents of the positive and negative battery string cables. If the battery string is not configured with the neutral wire, measure the current of either the positive or negative battery string cable. The following uses the scenario where the battery string is configured with the neutral wire as an example. 2.2 Installing a BIM • Voltages on the BIM cable are hazardous. Therefore, wear insulation gloves when performing operations on the cable. • The red terminal is positive, and the black terminal is negative. Connect battery terminals correctly. 1. Open the battery string switch. Connect the positive and negative BIM cables respectively to the positive and negative wiring terminals or poles of the battery. Bolt Spring washer Flat washer OT terminal Battery connecting kit Use an insulated torque wrench during battery installation. The terminal torque depends on battery specifications. • M6: 4–6 N·m • M8: 13–15 N·m • M10: 15–20 N·m 2. Secure the BIM. • Ensure that the attaching area is clean. • Ensure that the BIM fastener is evenly and firmly attached. • Ensure that terminals are visible when installing the BIM. (1) Strip the adhesive tape from the BIM fastener. (2) Attach the BIM and press it for more than 10 seconds. 2 3. After connecting all power cables to the system, connect the BIM cable to the BIM panel port. • Before connecting the cable to the BIM panel port, connect all power cables to the system. • Before disconnecting the BIM cable, disconnect the cable from the BIM panel port. • After the product is installed, if the battery is not charged for more than 30 days, you are advised to remove the iBAT from the battery cables. 2.3 Installing a CIM The CIM must be installed 1 meter above the ground to ensure proper wireless communication between the CIM and the BIM. 1. Connect the antenna delivered with the CIM to the RF_Z port on the CIM. 2. Strip the adhesive tape from the CIM fastener, and attach the fastener to the bounding frame on the CIM fixed mount. Then press the fastener for more than 10 seconds. • Ensure that the attaching area is clean. • Ensure that the fastener is firmly attached with even strength. 3. Clamp the CIM to the fastener. 3 3 Installing Equipment (Battery Rack) 3.1 Installation Position BIM installation position Top installation Side installation BIM Battery Battery BIM The battery appearance is for reference only. CIM installation position Top installation Side installation CIM CIM BIB BIB BCB box BCB box Hall effect Hall effect sensor sensor 4 • When selecting a position to install the CIM, ensure that the communication distance between the CIM and the BIM is not greater than 15 meters. • Dimensions (L x W) of the center hole of the Hall effect sensor are 40.5 mm x 30.5 mm (LEM) or 40.5 mm x 40.5 mm (TAMURA). • If the battery string is configured with the neutral wire, measure the currents of the positive and negative battery string cables. If the battery string is not configured with the neutral wire, measure the current of either the positive or negative battery string cable. The following uses the scenario where the battery string is configured with the neutral wire as an example. 3.2 Installing a BIM Installing a BIM by referring to section 2.2 "Installing a BIM." 3.3 Installing a CIM Installing a CIM by referring to section 2.3 "Installing a CIM." When installing the CIM in the battery switch cabinet, do not use the delivered antenna. Attach the external antenna to the top of the battery switch cabinet, and connect the antenna cable to the RF_Z port on the CIM. 3.4 Installing a Hall Effect Sensor 1. Route the positive and negative battery string cables through the Hall effect sensor. The positive and negative battery string cables must be routed in directions shown by arrows on the Hall effect sensors. The positive battery string cable routes from the UPS to the battery, and the negative battery string cable routes from the battery to the UPS. 2. Secure the Hall effect sensor to the positive and negative battery string cables using cable ties. If the positive or negative battery string cable is too thick to be routed through the Hall effect sensor, or the measurement range of the Hall effect sensor is insufficient, use multiple Hall effect sensors to detect the current of one battery string. The CIM supports the sum of the monitoring results of multiple Hall effect sensors, which is implemented by setting Multi-Hall cur. setting. 5 3.5 Installing an Adapter • Install an adapter if only the CIM communications cable connects to the UPS. • Prepare ST3.5x35 tapping screws, washers, and 6x30 plastic expansion sleeves by yourself.

In ECC scenarios, connect cables by following instructions in this section. DC input Smart ETH gateway In the ECC scenario, the CIM communications cable can also connect to the PoE switch. 6 When a battery system needs to be managed by multiple CIMs, the CIMs can be connected to northbound devices through straight-through cables (the ECC supports four CIMs in parallel). Smart ETH gateway 4.2 Connecting Cables • Connect the Hall effect sensor on the positive battery string terminal to the HALL_1 current monitoring port on the CIM, and connect the Hall effect sensor on the negative battery string terminal to the HALL_2 current monitoring port on the CIM. • The positive and negative battery string cables must be routed in directions shown by arrows on the Hall effect sensors. The positive battery string cable routes from the UPS to the battery, and the negative battery string cable routes from the battery to the UPS. BCB box J1 CIM BCB 1 EXDRV+ - 2 EXDRV- - 3 EXAUX+ - 4 EXAUX- - 5 OL OL 6 STA STA 7 DRV DRV 8 GND GND In the foregoing figure, the iBOX is equivalent to the CIM, and the iBAT is equivalent to the BIM. 7 5 Installing Cables (UPS Scenario) 5.1 System Networking This chapter uses the UPS scenario where the CIM power cable connects to an adapter, and the CIM communications cable connects to the UPS as an example to describe how to connect cables. If only the UPS is used, connect cables by following instructions in this section. AC input Adapter When a battery system needs to be managed by multiple CIMs, the CIMs can be cascaded through RS485 buses for capacity expansion, and then connected to northbound devices (the UPS supports four cascaded CIMs). 8 5.2 Connecting Cables 1. Connect the cable between the CIM and the Hall effect sensor. • If each of the positive and negative battery string cables connects to one Hall effect sensor, connect the Hall effect sensor on the positive battery string terminal side to the HALL_1 current monitoring port on the CIM, and connect the Hall effect sensor on the negative battery string terminal side to the HALL_2 current monitoring port on the CIM. • If each of the positive and negative battery string cables connects to two or more Hall effect sensors, connect the Hall effect sensors on the positive battery string terminal side to the former HALL current monitoring ports, and the Hall effect sensors on the negative battery string terminal side to the latter HALL current monitoring ports. For example, if each of the positive and negative battery string cables connects to two Hall effect sensors, connect the Hall effect sensors on the positive battery string terminal side to the HALL_1 and HALL_2 current monitoring ports on the CIM, and connect the Hall effect sensors on the negative battery string terminal side to the HALL_3 and HALL_4 current monitoring ports on the CIM.
