5.2 Replacement of main component
Danger:
The PowerCube-M2 is a high voltage DC system, operated by qualified and
authorized person only.
Danger:
Before replace the main component must shut off the maintenance battery
string’s power. Must confirm the
D+
and
D-
terminal are without power. The turn off
progress refer to chapter 3.6.5.
5.2.1 Replacement of Battery Module
A new battery module can be add onto an existing system at any time. Please make sure the new
battery module has an equivalent voltage level (OCV) compare to existing modules. In a serial
connection system, the new module, even has a higher SOH, will follow the system worst SOH
condition module to perform.
