Safety Information
Warnings
This equipment should not be used by anyone (including children) with reduced physical,
sensory or mental capacity, or anyone lacking in experience or knowledge, unless they are
provided with supervision or prior instruction in how to use the equipment by the person
responsible for their safety.
The GLB Wallbox range of charging stations is designed exclusively for charging electric
vehicles.
The GLB Wallbox must be grounded through a permanent wiring system.

EN
4
Do not install or use the GLB Wallbox near flammable, explosive, harsh, or combustible
materials, chemicals, or vapors.
Turn off input power at the circuit breaker before installing, configuring or cleaning of the GLB
Wallbox.
Use the GLB Wallbox only within the specified operating parameters.
Never spray water or any other liquid directly at the GLB Wallbox. Never spray any liquid
onto the charge handle or submerge the charge handle in liquid. Store the charge handle in
the dock to prevent unnecessary exposure to contamination or moisture.
Do not use this equipment if it appears to be damaged or if the charging cable appears to be
damaged.
Do not modify the equipment installation or any part of the product.
Do not touch the GLB Wallbox’s terminals with fingers or any other objects.
Do not insert foreign objects into any part of the GLB Wallbox
Cautions
Do not use private power generators as a power source for charging.
Incorrect installation and testing of the GLB Wallbox could potentially damage either the
vehicle’s Battery and/or the GLB Wallbox itself.
Do not operate the GLB Wallbox in temperatures outside its operating range – see technical
data.
Notes
All installation must be carried out by an authorized installer and comply with local installation
regulations.
Ensure that the GLB Wallbox’s charging cable is positioned so it will not be stepped on, driven
over, tripped on, or subjected to damage or stress.

EN
5
Unroll the charging cable to prevent it from overheating.
Do not use cleaning solvents to clean any of the GLB Wallbox’s components. The outside
of the GLB Wallbox, the charging cable, and the end of the charging cable should be
periodically wiped with a clean, dry cloth to remove accumulation of dirt and dust.
Be careful not to damage the circuit boards or components during installation.
Refer to local standards and regulations not to exceed charging current limitations.
Adapters for charging connectors are not allowed to be used.
Cord extension sets for charging cable are not allowed to be used.
To even out the load, it is important to rotate the phases when connecting several of GLB
wallboxes to the same supply. Note that 1-phase charging is common in electric vehicles and
L1 the GLB is used for this purpose.
Ventilation signal from EV is not supported.
Cord extension sets for charging cable is not allowed to be used.

Electrical vehicles (EV) software and the GLB Wallbox firmware are continuously updated.
To make sure that the GLB wallboxis working properly, it is necessary to update the firmware
and it requires a communication card.
Communication cards are available as an accessory.
GLB Wallboxes installed in a cluster only need the
master to have the communication card installed.

Installation Instructions
1) Chargers without RCCB or RCBO included in the enclosure must have Residual Current
protection and must be protected with a max 32A fuse in the supply distribution box.
2) Chargers without RCCB Type B fitted or DC fault protection in the enclosure must in
accordance to IEC 60364-7-722 be protected with a Residual Current Device (RCD) Type B.
3) 3-phase chargers equipped with a Residual Current Circuit Breaker (RCCB) must be protected
with a max 32A fuse in the supply distribution box.
4) 1-phase chargers fitted with a Residual Current Breaker with Overcurrent Protection (RCBO)
can be connected in parallel. This group of chargers must be protected by a backup fuse in
the distribution box. The backup fuse shall not exceed 125A.
• Calculate to determine the maximum operating current. Use conductors that are sized in
accordance with local wiring regulations. The selected cable must be able to sustain periods of
constant load of up to 32A. Manufacturers recommendation is to use minimum 6mm² conductors.
• Calculate the distance to ensure minimal voltage drop.

Installation Instructions
1. Read Safety information. The installation must be carried out by an authorized installer.
2. Select the appropriate group fuse (1x16A - 3x32A) and cable area for the electrical
installation. Some countries require earth fault breakers to be installed. Follow local country
regulations and select the appropriate earth fault equipment for the electrical installation.
NOTE! Due to high currents for a long time in the cable, there is a high risk of voltage drop if
the cable is under-dimensioned which can damage the electronics in an EV.
3. Fill in the fuse and cable information in the Warranty form located in the installation manual
that is included in the box.
4. Mount the GLB Wallbox according to the installation sketches. There is a drill template at the
back side of the box.

Depending on the size of the fuse, overload
may occur, primarily at the property’s meter
fuse. The wallbox’s charging current can be
reduced using the switches on the mainboard
(refer to Mainboard simplified connection
diagram (figure 9).
The power supply must be turned off before
setting of the DIP switches

Remote Control function
The wallbox is equipped with a potential-free contact input, where charging can be activated and
deactivated. The charger’s remote control capability allows charging to be controlled externally
through, for example, a relay outlet such as a timer or other superordinate control unit.
Charging can be verified in two ways:
• Activate charging by opening the circuit between the Remote Control connection blocks. This
option is the factory setting.
• Activate charging by closing the circuit between the Remote Control connection blocks.

Installation Instructions
DLM reduces charging current when demand of current elsewhere increases. Simple to say, the GLB
Wallbox balance the charging current that you will get as much power as possible to the EV that is
available in the system without any risk to overload the mains fuses.
The following energy meters are approved:
• GNM1D-RS485
• GNM3D-RS485
• GNM3T-RS485 (current transformer 3-phase. Max current is based installed current transformer)
• CG EM 112
• CG EM 270
• CG EM 271
For use in systems with local electricity produktion (solar-, wind etc)
• GNM3D-LP RS485
• GNM3T-LP RS485N (current transformer 3-phase. Max current is based installed current
transformer)
Note the energy meter’s Modbus address must be set to 2, 100 or 101.
Adress 2: Recommended for a stand alone GLB Wallbox. Setting for SW1 CC2 is valid and charging
process are paused if available current drops below 6A.
Adress 100 or 101: Only recommended when multiple GLB Wallbox are connected in a grid.
Minimum charging current is 6A and charging process is not terminated by the DLM function. This
mode require an installed wifi module.
The energy meter continually measures the total energy consumption for each phase. The data is
transmitted to the GLB Wallbox, that then is reducing the charging current when necessary in order to
prevent the mains fuses from tripping.
In one-phase systems, the energy meter needs to be installed to same phase as the GLB Wallbox.

• Config energy meter in distrubution box to Modbus address no.2 (9600 baud, no parity, one stop
bit)
• Config SW1 (DIP 1-3) for max current (refer Setting the amperage for main fuses)
During installation of DLM, the amperage setting of the SW1 (DIP1-3) must be adjusted to correspond
with the size and strength of the main fuses.
The SW2 (DIP 1-3) which controls the charger’s maximum permitted charging current should be set to
the recommended current values outlined below, when DLM for individual chargers is activated.
