memodo EPS BOX PRO Residential Power System and Smart Meter

Please read this manual carefully before use to avoid improper operation.

Introduction

Basic Features

EPS BOX PRO is a auxiliary product of AIO H3/H3. EPS BOX PRO is suitable for the residential power system and integrates Smart Meter, Breaker, ATS and other devices internally; It features convenient installation, and the power supply status of the load can be switched automatically or manually. The automatic switching time is less than 3s. It can automatically switch to the Reserve power supply side (EPS terminal of the inverter) to supply power to the load when the power grid fails. It can switch to the power grid side to supply power to the load when the power grid is restored.

Note

Only authorized personnel are permitted to set the connection.

Wiring Diagram

The wiring diagram of EPS BOX PRO with H3 and AIO H3 is shown below.

Note:

When the inverter is in off-grid state, the load power shall not exceed the maximum output power of the off grid inverter. We will not be responsible If the machine is unable to operate normally due to high load;
When the grid voltage is normal, the maximum current of both the UTILITY SUPPLY port and the Load port should not exceed 63A.

Installation

Check for Physical Damage

Ensure that the EPS BOX PRO is intact during transportation. If there is any visible damage, such as cracks, please contact your dealer immediately.

Mounting

Installation Precaution

Ensure that the installation site meets the following conditions:

Not in direct sunlight.
Not in areas where highly flammable materials are stored. Not in potential explosive areas.
Not in the cool air directly.
Not near the television antenna or antenna cable.
Not higher than altitude of about 2000m above sea level. Not in environment of precipitation or humidity(> 95%). Under good ventilation condition.
The ambient temperature in the range of -25°C to +60°C. The slope of the wall should be within +5*.

The wall hanging the EPS BOX PRO should meet conditions below:

Solid brick/concrete, or strength equivalent mounting surface;
EPS BOX PRO must be supported or strengthened if the wall’s strength isn’t enough (such as wooden wall, the wall covered by thick layer of decoration).

Please avoid direct sunlight, rain exposure, snow laying up during installation and operation.

Space Requirement

Position	Min Distance
Left	500mm
Right	300mm
Top	300mm
Bottom	500mm

Tools required for installation:

Marker pen;
Electric drill (drill bit set 8mm); Crimping pliers;
Stripping pliers;
Screwdriver.

Mounting Steps

Fix the bracket on the wall
Choose the place you want to install the EPS BOX PRO.
Please select solid brick-concrete structure and concrete wall for installation location. If other types of wall are selected, the wall must be made of fire-retardant materials and meet the load bearing requirements of the equipment.
The dimensions (Unit: mm) on the back of the machine are as follows,
Before drilling holes, please ensure the distance (Unit: mm) between the machine and nearby objects.
Place the bracket on the wall and mark the position of the 4 holes from bracket.
- Danger: Before drilling, please make sure to avoid the water and electricity lines embedded in the wall to avoid danger.
Drill holes with electric drill, make sure the holes are at least 50mm deep and 8mm wide, and then tighten the expansion tubes.
- CAUTION: Please pay attention to safety when using the tools. Unsafe use of the drilling tools may cause damage to the body.
Insert the expansion tubes into the holes and tighten them. Install the bracket with the expansion screws.

Match the EPS BOX PRO with wall bracket

Mount the EPS BOX PRO to the bracket. Secure the EPS BOX PRO with the M5 screw and washer.

Electrical Connection

Wiring Connection

Open the box cover, remove the fixing screws of the insulation board, and then take out the insulation board.
Pass cable through cable gland and wire according to the marks at the bottom of the box. After wiring all cables, restore the insulation board to its original position and then tighten the box cover.

Utility Supply & Load Wiring Instructions

Earth Connection

Trim 6mm of insulation from the wire end.
Insert striped wire into earth terminal and ensure all conductor strands are captured in the earth terminal,Crimp earth terminal by using a crimping plier. Put the earth terminal with striped wire into the corresponding crimping pliers and crimp the contact.
Use the crimping pliers to press the grounding wire into the ground terminal, screw the ground screw with screwdriver as shown below:

Check After Installation

Check After Installation

Check and confirm that the equipment is installed securely and reliably.
Check if the grounding wire is correctly, firmly and reliably connected.
Check if the wire is correctly, firmly and reliably connected (confirm if the phase sequence is correct).
Check if the communication wire is correctly, firmly and reliably connected.

Note

The default state of the automatic transfer switching equipment is manual mode.
If automatic switching is required, the dual power transfer switch needs to be modulated to automatic mode.
