4. Requirement Materials and Tools
4.1 Part list
The following parts come standard with each iPQMS package. The number and type of connector
clamps will depend on the application.

• Mount each component securely, placing the mounting blocks between the iPQMS/RU and
mounting surface
5.3 Clamp Installation
The iPQMS uses two different types of clamps based on the battery connection. C-Type clamps are
used for batteries connected by busbar; O-Type clamps for batteries connected via cable. It is not
uncommon for both clamp types to be used for an installation. O-Type clamps are commonly used
on jumpers between racks.
All clamps house a basic PCB board which is used to fuse the connection between the battery and
sensing cables. This manual refers to (2) board types, Voltage (Vs) only and Voltage + Current
(Vs+Is). PCB boards of the (Vs) variant have one fuse while (Vs+Is) boards have (2) fuses. These
clamps must be installed in the correct sequence as detailed in section 5.4 or in the cable
connection map provided with your system.
(1) Prepare For Connection
1. Organize clamps based on type and verify all clamps are present
2. Using tape and a marker, number the batteries as shown on the provided connection diagram if
they are not already numbered

5.6 Total Voltage/DC Power Connection
The total voltage cable monitors string voltage in real-time. The total voltage cable connects to the
main positive and negative bus of the battery system then back to the iPQMS MPU.
Each cable has a 1A fuse for voltage protection. Be sure to check the fuse before installation.
(1) Connect the Fuses to the Total Voltage Cable
1. Crimp the positive fuse to positive total voltage cable
2. Crimp the negative fuse to the negative total voltage cable
(2) Connect to Battery System
1. Determine the best place to connect the total voltage cables on the most positive and negative
bus of the string
2. If using busbar connections, use the C-Clamp to connect to the busbar 3. If using cable
connections, connect directly to the O-type clamp under the (Vs) screw that goes into the cable

5.10 Connect Relaying Units / iPQMS
The iPQMS system can support up to (7) Relaying Units. These units are connected in daisychain.
Relaying Unit #1 connects to the iPQMS. Before connecting the Relaying Units together and to the
iPQMS, all sensing cable connections should be made.
(1) Set Relaying Unit Number
1. Each Relaying Unit must be assigned a number 1 through 7
2. Set the jumper to the number of the RU (Ex. RU#1 has jumper set to the “1” position)
3. If only using one RU, ensure the jumper is in the 1 position as shown below
(2) Connect the MPU to RU cable to RU#1
1. The MPU to RU cable is connected to the MPU from the factory
2. Run the cable from the MPU to RU#1
3. Each Relaying Unit has two rows of interface ports for connection between the MPU and RU#1
and to additional RU’s
4. Connect the appropriate cables to each port inside the RU, it does not matter which row of
ports the cables are connected to, however if using multiple RU’s, it is recommended to
connect the MPU to RU cable to the back row to allow more accessible connection of the RU
crossover cable
(2) Connect additional RU’s together
1. If using more than one RU, connect additional RU’s together using the RU Crossover cable
