4 Before installation
4.1 Recommended tools
• Smart phone, tablet or computer on Wi-Fi network
• Flat head screwdriver, max width 3 mm
• Multimeter, wire stripper
• Phase sequence tester
4.2 Internet access
N.B: For a more secure network connection, network
connection via LAN is preferred.
In order to transmit data to the load balancing function which
communicates with the charging station(s), Charge Amps Amp
Guard must be connected to the internet. A connection via either
Wi-Fi or LAN is possible for Charge Amps Amp Guard.
4.2.1 Wi-Fi connection
A Wi-Fi network connection with the following specifications is
possible for Charge Amps Amp Guard:
• Type: 802.11b/g/n
• Range: 2.4 GHz
• Wi-Fi signal strength: -80dBm or better (-30dBm equals very
good signal, -90dBm equals very poor signal).
• The network needs to have DHCP enabled to ensure an IP
address is automatically assigned to the Charge Amps Amp
Guard.

12
English
4.2.2 LAN connection
LAN network connection with the following specifications is
possible for Charge Amps Amp Guard:
• A network cable, at least Cat6.
• Normally, no firewall changes are necessary.
• The network needs to have DHCP enabled to ensure an IP
address is automatically assigned to the Charge Amps Amp
Guard.

English
5 Installation
To monitor all power usage, install Charge Amps Amp Guard
directly downstream the building’s main circuit breaker panel.
N.B: For single phase installations, L2 and L3 shall not be
used.
5.1 Mount Charge Amps Amp Guard
Before starting the mounting of Charge Amps Amp Guard,
remember that an additional slot will be needed on the DIN-rail for
mounting of the power supply.
1. Place the Charge Amps Amp Guard onto the DIN-rail.

14
English
5.2 Connect the current sensors
Charge Amps Amp Guard comes with three current sensors, one
for each phase.
1. Clamp the current sensor around the incoming phase. The
current sensors must be:
• Connected to the correct phase.
• Properly positioned around the main power cables.
• Mounted in the direction of current flow, as indicated by the
arrow on the current sensor which is illustrated in the picture
below.

15
English
2. Connect the sensor cartridge to the top of the Charge Amps
Amp Guard.
N.B: To secure proper contact, hold a hand under the Charge
Amps Amp Guard when connecting the sensor cartridge.

16
English
5.3 Connect the terminal block for
voltage measurement
If power generating equipment, such as solar panels or wind
turbines etc, is installed, connection of the terminal block for
voltage measurement is required on all phases.
If no power generating equipment is installed, connection of the
terminal block for voltage measurement is recommended on
one phase to ensure optimal performance of Charge Amps Amp
Guard.
IMPORTANT! Each phase (L1, L2, L3) must always be protected
by a circuit breaker and connected to the correct terminal
connector for the voltage measurement to function correctly.
1. Turn the power off at the main circuit breaker panel.
2. Connect the terminal block to the bottom of the Charge Amps
Amp Guard.
3. Connect phases and neutral to the supplied terminal block
according to the wiring diagram that best suits your installation
scenario:

17
English
• Wiring diagram installation with power-generating equipment:
connect all phases to the terminal block for voltage
measurement.
• Wiring diagram installation without power-generating
equipment: connect one of the phases to the terminal block for
voltage measurement.

18
English
• Wiring diagram - IT network* with power generating equipment:
connect all phases to the terminal block for voltage
measurement.
• Wiring diagram - IT network* without power generating
equipment: connect L1 and L2 to the terminal block for voltage
measurement.
*The IT-network type must be configured in the local management interface, see
chapter “6.3.2 Electrical settings”.

19
English
5.4 Mount and connect the power
supply
The power supply is pre-configured to supply 12 V to Charge
Amps Amp Guard. If needed, the voltage level can be adjusted by
using the adjustment screw on the front of the power supply.
1. Connect the power supply to the mains and insert the supplied
12V power cable to the power supply according to the picture
below.
IMPORTANT! Note the marking on the power supply! The cable
marked with the white lines shall go into +Vo!

2. Mount the power supply onto the DIN-rail.
3. Connect the 12V power cable to the sensor cartridge.
IMPORTANT! Be careful not to overpress the 12V power cable
when connecting it to the sensor cartridge!
4. Turn the power on at the main circuit breaker panel.
