and precautions carefully.
IMPORTANT SAFETY INFORMATION
This section contains important safety information for the Enerdrive ePOWER Inverter. Each time, before
using the Enerdrive ePOWER Inverter, READ ALL instructions and cautionary markings on or provided with
the inverter, and all appropriate sections of this guide. The Enerdrive ePOWER Inverter contains no user
serviceable parts. See Warranty section for how to handle product issues.
WARNING: FIRE AND/OR CHEMICAL BURN HAZARD
• Do not cover or obstruct any air vent openings and/or install in a zero-clearance compartment.
WARNING: FAILURE TO FOLLOW THESE INSTRUCTIONS CAN RESULT IN DEATH OR SERIOUS INJURY
• When working with electrical equipment or lead acid batteries, have someone nearby in case of an
emergency.
• Study and follow all the battery manufacturer’s specic precautions when installing, using and servicing
the battery connected to the inverter.
• Wear eye protection and gloves.
• Avoid touching your eyes while using this unit.
• Keep fresh water and soap on hand in the event battery acid comes in contact with eyes. If this occurs,
cleanse right away with soap and water for a minimum of 15 minutes and seek medical attention.
• Batteries produce explosive gases. DO NOT smoke or have an open spark or re near the system.
• Keep unit away from moist or damp areas.
• Avoid dropping any metal tool or object on the battery. Doing so could create a spark or short circuit
which goes through the battery or another electrical tool that may create an explosion.
WARNING: Shock Hazard. Keep away from children!
• Avoid moisture. Never expose unit to snow, water, etc.
• Unit provides 230 VAC, treat the AC output socket the same as regular wall AC sockets at home.
WARNING: Explosion hazard!
• DO NOT use the Enerdrive ePOWER Inverter in the vicinity of ammable fumes or gases (such as gas
bottles or large engines).
• AVOID covering the ventilation openings. Always operate unit in an open area.
• Prolonged contact to high heat or freezing temperatures will decrease the working life of the unit.

Material Prepare for Installation
Typical Wiring block diagram of the Enerdrive ePOWER Inverter:
Battery Bank:
• The use of deep cycle battery is highly recommended for power inverter application
• For battery size, you need to identify how long you wish to operate the load(s). Enerdrive does
recommend that you purchase as much battery capacity as possible. See more on “Estimated Run time
and Load” in Section 4.
• Please use 12V Battery Bank system for 12V DC Input Inverter (EN1104S). Use 24V Battery Bank system for
24V DC Input Inverter (EN1105S-24). Using 12V DC Input Inverter on 24V Battery System will damage
the inverter and may catch re.
Fuse or Circuit Breaker:
• DC-rated fuse or DC-rated circuit breaker connected along the DC positive line is required.
• Select a fuse or circuit breaker with 60A/16V minimum rating for the 12V DC Input Inverter(s) and 35A/
30V minimum rating for the 24V DC Input Inverter(s).
• Based on the size of the battery bank chosen on the 12V or 24V Battery Bank system above, determine
the overall short circuit current rating of the battery bank from the battery manufacturer. The fuse or
circuit breaker chosen has to be able to withstand the short circuit current that may be generated by the
battery bank.
Disconnect Switch:
• Select a Disconnect Switch with the same or higher rating of the selected fuse or circuit breaker from
the above.
• The Disconnect Switch is used to disconnect the DC power between the power inverter and the battery
bank during service, maintenance or trouble shooting.
DC Input Cable:
• Use of low resistance wire is required for all the DC connections between the inverter and the battery
bank.
• Use minimum 10mm2 cable with a maximum length of 1.5m for 12VDC inverter and 6mm2 cable with a
maximum length of 1.5m for 24v inverter systems.

Installing the Enerdrive ePOWER Inverter System
WARNING: Electrical Shock Hazard
The unit ‘On/O’ switch does not disconnect the DC power from the battery. Use the DC Disconnect
Switch or disconnect the DC input cables connection to disconnect the DC power from the battery before
working on any circuits connected to the unit. Failure to follow these instructions can result in death or
serious injury.
CAUTION: Reverse the DC Input terminal will damage the unit and cannot be repaired. Damage caused by
reverse polarity connection is not covered by the warranty.
ePOWER Inverter Installation:
• Choose an appropriate mounting location.
• For indoor use, the orientation of the unit can be mounted in any direction except with the DC Input
panel facing downwards.
• For RV installation, the unit has to be mounted horizontally.
• Use mounting template below to mark the positions of the mounting screws.
• Drill the 4 mounting holes and place the inverter in position and fasten the inverter to the mounting
surface.
ePOWER Inverter DC Input Connection:
CAUTION: Reversing the DC Input terminal will damage the unit and cannot be repaired. Damage
caused by reverse polarity connection is not covered by the warranty.
• Connect one end of the negative DC input cable to the ePOWER Inverter DC negative terminal. Connect
the other end of the negative DC input cable to the battery negative terminal.
• Make sure the Disconnect Switch is in the OFF position.
• Connect one end of the positive DC input cable to the ePOWER Inverter DC positive terminal. Connect
the other end of the positive DC input cable to one of the terminal of the Disconnect Switch.
• Connect a DC input cable between the other terminal of the Disconnect Switch and one side of the
terminal of the fuse holder.
• Connect a DC input cable between the other terminal of the fuse holder and the battery positive terminal.
• Install the selected fuse to the fuse holder.
• Turn Disconnect Switch to ON position.
