Over Current Cut Out
Series II inverter/chargers are protected from over-current conditions. When the load being run
demands more current than the inverter can safely supply, the inverter will momentarily shutdown,
turn off if it encounters an over-current condition for approximately 20 seconds (a prolonged short-
circuit) or if the AC output is connected to another AC power source (shorepower or generator).
Battery Type Optimization
Series II inverter/chargers are designed to prevent damage to and extend the useful life of your
batteries by regulating the charging voltage and duration. To do this, the inverter/charger must be
configured for the type of batteries in the system. The Series II is pre-configured for optimum
charging of gel cell type batteries at 14.1 volts in bulk charging mode, and 13.5 volts in float charging
mode. For liquid lead-acid batteries, you can reset the Series II using the RC7 remote control to bulk
charge at 14.5 volts and float charge at 13.4 volts. For a complete discussion of batteries and battery
charging techniques, see the Batteries and the Three-Stage Battery Charger sections of this manual.
Charge Rate Regulation
Batteries can overheat if the charge rate is too high. The Series II inverter/charger protects your
batteries by enabling you to limit the charge rate using the RC7 remote control. The charge rate is
set at the factory to 100% of maximum, which may be up to 140 amps depending upon the model
you have purchased (see Appendix D: Specifications to determine the maximum possible charge
rate for your model). For smaller battery banks, this may be too high.
The highest charge rate recommended is determined by dividing the battery bank' s amp hour
capacity by a factor of three or five (3 for gel cell - 5 for lead acid).

Setting the charge rate at the highest recommended level is best when the objective is to charge the
batteries as quickly as possible. A much lower setting can be used in installations where AC power is
typically available for periods of several hours. There is more than sufficient time for a 400-amphour
battery bank to be recharged in 24 hours at a 25-amp setting.
Example: 25 amps X 24 hours = 600 amp/hrs.
Caution: Excessively high charge rates can overheat a battery. If battery bank capacity is low, set
the battery charge rate to the minimum setting.

Questions and answers
how do you clear error light and alarm from remote control
To clear the error light and alarm on the Trace Engineering Legend remote control, follow these steps:
1. Identify the Error – Check the LED indicators on the remote control to determine the cause of the alarm (e.g., low battery voltage, high temperature, etc.).
2. Resolve the Issue – Address the underlying problem based on the error type:
- If the battery voltage is too low or high, check and adjust the battery condition.
- If there is a high-temperature warning, allow the unit to cool down.
- Ensure all connections (battery and AC output) are secure and clean.
3. Reset the Inverter – Turn the inverter off, wait a few seconds, and turn it back on.
4. Monitor the System – Observe the LED indicators to confirm the error is cleared.
If the issue persists, further troubleshooting may be required.
