Safety Information

DANGER: Risk of fire, electric shock, explosion, or arc flash. Always use appropriate Personal Protective Equipment (PPE) and follow safe electrical work practices. Do not short-circuit, open, or dismantle the battery. If the battery is damaged, do not touch the electrolyte. Do not install in environments exceeding 113°F (45°C).

WARNING: Do not connect other battery types to the system DC load. The battery is heavy; use proper lifting techniques. Do not replace fuses yourself. Ensure ventilation openings are not obstructed.

Installation

NOTICE: Do not connect multiple batteries in series. Parallel connection is permitted. The battery must be installed upright.

1. Check the battery for visible damage. Ensure the top surface and terminals are clean, dry, and free of corrosion.
2. Ensure the battery is turned off (LED off).
3. Prepare terminal bolts (M8 1.25x12mm), lock washers, flat washers, and cable ring lugs (do not use stainless steel lugs).
4. Install a Class T DC fuse (100A, 32V) on the positive cable as close to the battery terminal as possible.
5. Attach the negative cable to the negative terminal.
6. Attach the fused positive cable to the positive terminal.
7. Torque all terminal bolts to 106 in-lb (12 Nm).

Battery Charging

You may charge the battery when the State of Charge (SoC) is greater than 10%. If the reserve shutdown event has occurred (SoC < 10%), press the Power button to engage power before charging. Avoid using heavy loads during charging to prevent thermal protection mode. Do not turn off the unit to disconnect the battery while charging.

Power Button and LED Indicator

The Power button integrates an LED indicator:

• Steady on: Battery is discharging.
• Slowly blinking: Battery is being charged.
• Off: Battery power is disabled.
• Short flash: Low battery condition.
• Rapid flashing: Alarm condition.
