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

English
4.2 Internet access
IMPORTANT!
The Charge Amps Amp Guard must be connected to the
internet to transmit data to the load balancing function which
communicates with the charging station(s).
The customer must therefore provide an internet connection via a
network cable (LAN) or Wi-Fi (802.11b/g/n 2.4 GHz).
• LAN connection, if available, is preferred for a more secure
connection to the internet. The network cable must be at least
Cat6.
• Normally, no firewall changes are necessary.
• Wi-Fi signal strength needs to be -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.

English
5 Installation
Install the Charge Amps Amp Guard directly downstream of the
building’s main circuit breaker panel to monitor all power usage.
For single-phase installations, L2 and L3 shall not be used.
5.1 Mount Charge Amps Amp Guard
1. Pull the DIN-rail lock downwards and twist the Charge Amps
Amp Guard onto the DIN-rail.
2. Secure in place by pushing the DIN-rail lock back in place.
Please note that an additional slot will be needed for the power
supply.

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 mounting direction is marked on the current sensor.
The arrow must point in the current direction.
IMPORTANT!
The current sensors must be connected to the correct phase and
properly positioned around the main power cables according to
the direction indicators on the clamps.
2. Connect the sensor cartridge to the top of the Charge Amps
Amp Guard.

5.3 Connect voltage measurement
For installations with power-generating equipment
Solar panels, wind power, or plans to introduce such equipment
require the voltage measurement to be connected.
For installations without power-generating equipment
Connection of the voltage measurement is optional.
Do not remove the terminal block in the bottom of the Charge
Amps Amp Guard as it may be needed if voltage measurement is
connected in the future.
IT grid networks
IT grid is used in parts of Norway, Belgium and Albania.
In IT grid installations, L2 must be connected to both L2 and N.
The network type must also be configured, see chapter Electrical
Settings.
IMPORTANT!
Each phase must be connected to the correct terminal connector
for voltage measurement to function correctly. L1, L2 and L3 must
be protected by circuit breakers in the normal way.
1. Turn the power off at the main circuit breaker panel.
2. Connect phases and neutral to the supplied terminal block.

16
English
3. Connect the terminal block to the bottom of the Charge Amps
Amp Guard.
5.4 Mount and connect the power
supply
The power supply provides 12V to the Charge Amps Amp Guard.
The power supply is pre-configured to 12V. If needed, voltage can
be adjusted using the adjustment screw on the front of the power
supply.
1. Connect the power supply to the mains (L, N) according to the
labels on the power supply, i.e. N to AC(N) (left side) and L1 to
AC(L) (right side).
2. Insert the supplied 12V power cable into the power supply
according to the label on the power supply, i.e. marked cable to
+Vo (left side) and black cable to -Vo (right side).
3. Mount the power supply onto the DIN-rail.
4. Connect the 12V power cable to the sensor cartridge.

English
5. Turn the power on at the main circuit breaker panel.
5.5 Connect the Wi-Fi antenna
1. Mount the supplied Wi-Fi antenna to the Charge Amps Amp
Guard.
2. NB: Depending on the type of cabinet, an external Wi-Fi
antenna may be needed. The external antenna must be of non-
grounded type.
5.6 Connect the LAN cable
If applicable, connect the network cable to the LAN port.
The cable must be Cat6.
WARNING! Note the marking on the power supply.

6 Configuration
Once the electrical installation has been completed, Charge Amps
Amp Guard needs to be properly configured.
6.1 Connect to the Charge Amps Amp
Guard Wi-Fi hotspot
IMPORTANT!
Only 2.4GHz Wi-Fi is supported.
The Wi-Fi hotspot is only active for 10 minutes after power up.
To restart Charge Amps Amp Guard, see chapter Reset.
1. Connect to the Charge Amps Amp Guard Wi-Fi hotspot using
a smartphone, tablet or a computer. To avoid conflicting Wi-
Fi, set to airplane mode, turn on Wi-Fi, then connect to the
hotspot.
2. The network name, i.e. the SSID, is AG_******* (* = The last 7
digits/letter of the Charge Amps Amp Guard’s serial number).
The serial number can be found on the front label of the
Charge Amps Amp Guard (the one with a QR-code) and on the
front page of the Quick Guide.
Enter the Charge Amps Amp Guard PIN as the Wi-Fi password
to sign in to the Wi-Fi hotspot.
The PIN is an 8-digit code that can be found on the Charge
Amps Amp Guard front label and on the front page of the
Quick Guide.
