GARO LS4, LS4 Compact Public Charging

SAFETY INFORMATION

• The LS4 stations are designed exclusively for charging electric vehicles.
• All installation must be carried out by an authorized installer and comply with local country installation regulations. If any questions, please contact your local electrical authority.
• Refer to local standards and regulations not to exceed charging current limitations.
• To even out the load, it is important to rotate the phases when connecting several of LS4 stations to the same system. Note that 1-phase charging is common in electric vehicles and L1 (left side) and L2 (right side) in the LS4 is used for this purpose.
• Ventilation signal from EV is not supported. This means that test of “State D” is not possible.
• Adapters for charging connectors are not allowed to be used.
• Cord extension sets for charging cable is not allowed to be used.
• Do not use private power generators as a power source for charging.
• Incorrect installation and testing of the LS4 stations could potentially damage either the vehicles battery and/or the LS4 itself.
• Do not operate the LS4 stations in temperatures outside its operating range – see technical specifications.

GENERAL INFORMATION

• Each LS4 station is pre-programmed from factory and tested according to the specification from customer. There is no need for any programming or setup by installer during installation.

• Each LS4 station is individually marked with a unique
  “M-number” so that the installer can identify each LS4 station. The M-number label is located at upper right hand side corner behind the front door. When contacting GARO support, please have the M-number available.

• LS4 stations that are pre-configurated for backend-solution have the ChargeBoxID (CBID) labeled under the M-number label.

INSTALLATION

1. Mount the LS4 and install the supply cable. See picture 1-4.
   Phase-rotation is recommended in order to achieve even load on all phases when several LS4 stations are installed to same mains. For example:
   1st LS4: L1, L2, L3
   2nd LS4: L3, L1, L2
   3rd LS4: L2, L3, L1
   And so on….
   Note: When DLM is pre-configurated from factory, follow the marked phase order label at incoming terminals. All pre-configured LS4 contains the information about this inside the cabinet
   The gasket at the bottom of the LS4 need to tighten properly around the mains cable in order to avoid dirt, dust, bugs etc to enter the LS4. See picture 4.
   Note! The touch protection cover need to fix with attached screws to ensure proper earth bonding to the touch protection cover.

2. In cases with LS4 stations connected in a grid, install TP cable CAT6 with RJ45 connectors between each LS4 station and the provided ethernet router/switch (located ie. in the LS4 master. Se example of ethernet wiring diagram picture 5, 6.
   In cases with LS4 stations connected in a grid, installation of the LS4 stations need to follow the installation order in the attached Master/slave file. See table 1.

3. In cases with external energy meter (for DLM function), connect the energy meter communication terminals A- and B+ to LS4 Master station terminals 200 A-) and 201
   (B+). The energy-meters modbus adress must be set to

   2. The modbus RS-485 communication settings is: Baud 9600, 8bit, 1 stop bit,

   no parity

4. Turn on the electric power.

5. Test the LS4 station on both sides with a EVSE-tester or an EV. In cases where authorization (by RFID tag or similar) is needed to start charging please contact the backend administrator.

6. Fill in the warranty form completely.

NORMAL USE

Connect the charging cable to the EV.
If authorization is activated, please hold a valid RFID-tag against the RFID reader on the side of the LS4 you want to use or use the operator app to authorize charging.
Charging will start instant if the EV is ready for charging. See your EV charging manual.
When finishing charging, follow the EV’s instructions.
After charging: Release the charging cable from your EV and place the charging cable at designated place.

SERVICE INFORMATION

Care and maintenance GARO charging station LS4:
The warranty will only remain valid if service is performed. Service is performed once a year and must be documented. General authorization EL is required to perform service, i.e. only a qualified electrical contractor should perform the service. The service is performed by inspecting the charging station’s exterior and interior parts, manipulating components and conducting a functional inspection.
If the charging station is connected to a web portal or otherwise controlled from an external system via a service  provider, the service personnel must contact the service provider before a scheduled service. This is to be able to carry out all steps in the service, but also to avoid automatic error reports being sent from the charging station when service starts that may lead to other service personnel being called out at great expense. Normally the instructions for the charging station indicate whether it is connected to a superior service.
If you have questions about service or a need for service, please contact your GARO retailer.
