Safety Precautions

RAK9155 is designed with full consideration for safety. However, all electrical appliances can be dangerous if used inappropriately. It can cause a fire or electric shock that leads to severe injury. For your protection, please read these safety precautions thoroughly.

• Instructions

Use designated cable. A non-designated cable use can cause an electric shock. Be sure to use the cable designated in this manual.

• Prohibitions

Do not damage cables. If you damage a cable, it can cause a fire or electric shock.

1. Do not work over or damage a cable.
2. Do not place heavy objects on a cable or pull the cable.
3. Do not place a heater near the cable, which may result in the cable overheating.
4. Do not tuck down a cable when installing in a rack.

• Instructions

Connect the power cable and the communication cable properly.

If you connect a power cable improperly, contact resistance will increase and it may damage the parts or cause a fire.

Insert the connector of the communication cable all the way in. If it is connected improperly, the system may be deactivated.

Installation

Pre-Installation Preparation

The equipment is heavy, ensure personal safety when carrying it. During installation, make sure the installer complies with all the necessary safety regulations to ensure personal safety. Do not place equipment and mounting kit on pedestrian walkways to avoid accidental damage to equipment.

Carry the Equipment

You can carry the equipment with both hands. If the equipment is lifted with one hand, a handle needs to be installed. The handle is fixed to the equipment with two M6 screws. Before lifting the equipment, please confirm that the screws are fixed securely. You can remove the handle before installing the device.

Figure 360: Handle installation

Installation

NOTE

The diameter of the pole that is supported by the brackets is 50-75 mm. If the pole diameter is more than this value, larger hose clamps can be used. The standard mounting kit does not include larger hose clamps. If needed, they should be purchased separately.

1. Fix the mounting bracket on the pole with three hose clamps.

Figure 361: Fix mounting bracket

2. Install two M6 screws on the back of the equipment, leave a gap of about 3 mm.
3. Connect the Cables to the circular connectors. The 4 pin cable connects to the Output port. The 2 pin cable connects to the PV Input 1 port. If second Solar Panel need to be connected, connect it to PV Input 2 port.

Figure 362: Install screws and connect cables

NOTE

The cables should be connected before installing equipment on the pole, otherwise it is difficult to do it. Before cable connection, make sure the pin definition of the cables connected to PV panels is correct.

4. First, hang the equipment on the mounting bracket, then tighten the two screws that were left loose and screw the other two screws to secure the mount.

Figure 363: Fixing the equipment to the pole

5. Loosen the screw at the lower-left corner of the equipment (there is a Ground indicator on the side), connect the ground wire using the screw provided to the equipment. To complete the ground connection, lead the ground wire to the ground.

Figure 364: Grounding

NOTE

The ground wire is not provided with the kit. Determine the actual distance needed before purchasing/procuring the ground cable.

Power ON and OFF

NOTE

Double-check the precautions for use in section Precautions for Use.

System Power ON

1. Press the Power Switch button, green LED should be blinking.

NOTE

When RAK9155 is connected to the solar panel during the day, it’s normal to see a green LED blinking without turning on the Power Switch button. Turn on the Power Switch even though the green LED is blinking. If RAK9155 does not connect to either the load or the solar panel, the green LED would be off in 2 minutes.

System Power OFF

warning

Confirmed that the system is off before taking off the DC cables.

1. Press the Power Switch button, the green LED should turn off.
2. Remove the PV INPUT cables first, and then the OUTPUT cable.

Transportation and Storage

Transportation

It is forbidden to encounter serious vibrations and shock during transportation.

Storage

If the system is not placed to use, it must be properly stored.

• It should be stored in 60% SOC status.
• It should be stored in a well-ventilated environment, Temp. <35° C, ROH <65%.
• It should be stored avoiding humid conditions.
• It should be stored in a place where it can be monitored by a professional.
