Installation check list and disconnecting the power supply
Installation checks
Note: Before installation, make sure of the following:
• Location for the electric vehicle charging station is already agreed upon with the property owner or supervisor
• The power supply cabling is rated according to the planned installation and local regulations
• Needed parts and accessories of the product are available
• Appropriate tools and accessories needed for the installation are available
• Power supply is disconnected
•For current leakage protection, a Type-A, # 30mA RCD (Residual Current Device) is required for vehicle charging
supply. If not already available, it must be installed.
•For short circuit protection, a separate circuit breaker must be installed. Circuit breaker breaking current should
be selected according to local regulations and configured maximum charging current at charging station (DIP
switch configuration).
Needed tools
• Comprehensive hand tool set including insulated screwdrivers
• Informative warning tags during the separation of the power supply, and preventive lock or other preventive measure for
circuit breakers
• Power tools: An electrical power drill with drill bits
• Electrical testing tools: Standard compliant multimeter (with accessories), standard compliant earth resistance meter (with
accessories)
• Charging station installation template (included in the product sales package)
Disconnecting power supply
To avoid both personal and equipment hazards, follow these installation steps:
1. Turn the circuit breaker to the "OFF" position to disconnect the power supply.
a) Lock the circuit breaker in the "OFF" position. Use a dedicated lock accessory or use other preventive means for
reconnection prevention.
b) Place a prohibition sign stating "Do not connect" to the locked switch.
2. Make sure there is no power supply at the power supply cabling. Measure with a multimeter.

Installation
Wall mounting and electrical connections
DANGER: Make sure the power supply for the charging station is disconnected before starting the installation.
Note: Before the installation, the location for the charging station must have been agreed upon with the
property owner or manager. The appropriate power supply cabling must also be available.
Note: Make sure that the wall material is capable of handling the weight of the charging station. In special
materials,use the appropriate fastening measures.
1. Select the correct installation height for the charging station. Use the installation template included in the package to mark
the screw locations.
2. Make sure that the marked spots line up horizontally and drill the holes according to the hole markings.
3. Remove the charging station cover.
4. Install the charging station. Follow option A), or option B), depending on the cable inlet.
8

Installing the charging station - Wiring Option A
When the cabling is installed through the bottom cable inlet
DANGER: Make sure the power supply for the charging station is disconnected before installation. Do not turn
power on until electrical wiring is finished.
1. Before installation of the charging station, it is recommended that the power supply cabling is prepared first.
Note: Leave the PE wire 20 mm longer than the other wires. This will make sure that it is the last remaining
connection if the cable is pulled by excessive force.
Recommended stripping length for wiring option A: 3-phase power supply
Recommended stripping length for wiring option A: 1-phase power supply
Recommended stripping length for wiring option A: 1-phase power supply for IT power grid
2. A rubber grommet is used to prevent dust and moisture entering the charging station. To prepare the grommet, make a
small cross shaped cut where the power cable enters the grommet.
9

3. Place the charging station against the wall according to the screw location markings. Mount the charging station on the wall
before routing the cable.
4. Pull the power supply cable through the cable inlet. Make sure the non-stripped part of the cable reaches past the strain
relief. There must be enough cable for restrain fixing and the electrical connections.
5. Route the cabling so that you are able to place the cable to the strain relief.
6. Attach the strain relief.
Note: The strain relief can be used in two ways depending on the cable diameter.
7. Separate the power supply wires and mark them if necessary.
8. Make sure the wires cannot come into contact with each other.
10

Installing the charging station - Wiring Option B
When the cabling is installed through the backside cable inlet
DANGER: Make sure the power supply for the charging station is disconnected before installation. Do not turn
power on until electrical wiring is finished.
1. Before installation of the charging station, it is recommended that the power supply cabling is prepared first.
Note: Leave the PE wire 20 mm longer than the other wires. This will make sure that it is the last remaining
connection if the cable is pulled by excessive force.
Recommended stripping length for wiring option B: 3-phase power supply
Recommended stripping length for wiring option B: 1-phase power supply
Recommended stripping length for wiring option B: 1-phase power supply for IT power grid
2. A rubber grommet is used to prevent dust and moisture entering the charging station. To prepare the grommet, make a
small cross shaped cut where the power cable enters the grommet.
11

3. Pull the power supply cable through the right-hand side power inlet before fixing the charging station to the wall. Make sure
the non-stripped part of the cable reaches past the strain relief. There must be enough cable for restrain fixing and the
electrical connections. Do not tighten the fixings yet.
4. Make sure the device is in a correct position according to the screw location markings. Mount the charging station on the
wall before routing the cable.
5. Route the cabling so that you are able to connect the cable to the strain relief.
6. Attach the strain relief.
Note: The strain relief can be used in two ways depending on the cable diameter.

Wiring for load balancing
The client charger units are connected to the host charger using the right-hand side cable inlet. A rubber grommet is used to
prevent dust and moisture entering the charging station. Before inserting the cables, make a small cut in the grommet for each
cable entering the cable inlet. Recommended cable type for RS-485: ELAQBY/ELAKY 2X2X0,6 or similar.

External input connection
Charlie-C has an input connector for a potential free control signal from a 3rd party unit. When signal occurs
in the input, Charlie-C will limit the maximum charging current to 8A. When the signal returns to the normal
state, the maximum charging current returns to the predefined value.
1. Connect the potential free output of the control unit to connector pins CC+ and CC- .
2. Set the DIP switch of the 3rd party control units to Normally Open or Normally Closed, according to the following table.
