Introduction

EPS Box-TP integrates two contactors which provides simple connection for users. It is compatible with equipment with backup function. Configured with EPS Box, customers just need to connect 3 wires between inverter and EPS Box. It can simplify the operation and improve security.

Overview:

Wiring Diagram
Note: the following is the wiring diagram of EPS BOX TP. It is necessary to connect the ON-GRID side of EPS BOX TP to the power grid, connect the EPS port to the EPS port of the energy storage machine, and connect the LOAD port to the load at home. The function of TP is to select the power of the load port from the GRID or the EPS port of the energy storage machine.
Note: According to Australian safety requirements, the neutral cables of the on-grid side and backup side must be connected together. Otherwise, the backup function will not work.

This diagram is an example for an application that neutral connects with the PE in a distribution box. For countries such as Australia, New Zealand, South Africa, etc, please follow local wiring regulations.

This diagram is an example for an application in which neutral is separated from the PE in the distribution box.
For countries such as China, Germany, the Czech Republic, Italy, etc, please follow local wiring regulations. Need internal or external eps box, connect PE and the off-grid N line.

Preparation

Package Contents
Before installation, make sure that nothing inside the package is damaged. The following items should be inside the package.

Tools
Before you start, get the following tools ready.

Mounting

• Step 1: Install the four cushion blocks on EPS Box -TP with self-tapping screws.
• Step 2: Use EPS Box-TP with cushion blocks as a template to mark the four holes’ position on the wall with a marker pen.
• Step 3: Drill holes with 6 driller carefully, make sure the holes are deep enough for installation. Install the expansion tubes through cushion blocks into the holes and tighten them.
• Step 4: Install the expansion screws with a screwdriver to fix the EPS Box-TP.

Wiring Connection

Step1: Grid String Connection
EPS Box-TP is designed for a three-phase grid. Per voltage range is 220/230/240V; frequency is 50/60Hz. Other technical requests should comply with the requirements of the local public grid.

Step 2: Grid Wiring

• Check the grid voltage and compare with the permitted voltage range (refer to technical data).
• Disconnect the circuit breaker from all the phases and secure against re-connection.
• Trim the wires:
  • Trim all the wires to 52.5mm and the PE wire to 55mm.
  • Use the crimping pliers to trim 12mm of insulation from all wire ends as below.

Note: Please refer to local cable type and color for the actual installation

A. EPS Wiring
Set the parts on the cable.

Crimp wires, screw twisting torque 0.8+/-0.1N m.

Put the sealing body and yarn trapper into the main body, screw the lock nut into the main body, and the torque is (2.5 + /- 0.5N m).

Insert the male end into the female end. For the rotation direction of the lock, please refer to the LOCK mark on the assembly.

B. ON-GRID Wiring
Separate the ON-GRID plug into three parts as below.

• Hold middle part of the female insert, rotate the back shell to loosen it, detach it from female inset.
• Remove the cable nut (with rubber insert) from the back shell.

Slide the cable nut and then Install the back shell onto the cable.

Push the threaded sleeve into the socket, tighten up the cap on the terminal.

Remove the ON-GRID connector: Press the bayonet out of the slot with a small screwdriver or the unlock tool and pull it out, or unscrew the threaded sleeve, then pull it out.

C.Load Wiring
