4. Installation Instructions
4.1. Safety Instructions
The content in this document must be followed in order to ensure safe operation of Nuvation
Energy BMS.
The G5 High-Voltage BMS is to be installed in a location with restricted access.
Only skilled persons may install or service a system containing hazardous
voltages that may be present when the system is energized.
Do NOT energize the system until all connections to the Stack Switchgear unit
and Cell Interface modules have been made.
The wiring of the battery cell voltage and temperature sensing should be
verified before connecting to the Cell Interface modules. The temperature
sensing must be isolated from the cell voltage sensing. Although the Cell
Interface includes protective circuitry to make it more resilient to brief wiring
errors, the same circuitry can result in the battery cells being slowly
discharged. Over time, these wiring errors can cause damage to the Cell
Interface and/or the cells.
Properly insulate or remove any unused wires. Unused wires can couple
excessive system noise into Nuvation Energy BMS which can disrupt
communication and lead to undesirable behaviors.
Nuvation Energy BMS relies on your system charger to charge the battery
cells; do not leave your charger off while Nuvation Energy BMS is powered
from the stack for prolonged periods of time. Nuvation Energy BMS should be
shut down when the system is in storage to minimize the drain on the cells.
Insulated handling is required of any connector carrying potentials over 60 V
DC relative to chassis.
Please be aware of high voltages present in your system and follow all
necessary safety precautions.
The provided module enclosures are not fire enclosures.
