ALERT!
Immediately recharge the battery pack if it measures OCV < 3.90V. The terminal will go into
hibernate state when it reaches 3.60V.
When stored or not installed, Qualcomm recommends auditing the battery pack open circuit
voltage (OCV) every six months to ensure that it does not drop below 3.90V. If the storage
temperature is greater than 85° F, the audits should take place more frequently. Immediately
recharge the battery pack if it measures OCV < 3.90V. Batteries that sit for more than six
months must be recharged. You can use a battery charger or run external power to a TT210
unit for a couple of hours for a full charge.
TT210 Power/Accessory Cable - Optional
The TT210 power/accessory cable connects the TT210 system terminal to the trailer’s 7-way
electrical system. The cable also interconnects any optional accessories to the TT210 system
terminal. The three optional accessories allow customers to optimize the system with a cargo
sensor, door sensor, and/or an auxiliary sensor. The blue wire is crimped to a fuse holder that
has a 3-amp, fast-acting ATM type automotive fuse and connects to pin 7 of the 7-way. The
white wire connects to pin 1 of the 7-way. The illustration shows the various cable assemblies.
