English
4.2 Internet access
IMPORTANT!
Charge Amps Amp Guard must be connected to the internet to
supply data to the Load Balancer Function which communicates
with the charging station(s).
The customer must thus 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 shall be at least
CAT6-classified.
• Normally, no firewall changes are needed.
• Wi-Fi signal strength need to be -80dBm or better (-30dBm
equals very good signal, -90dBm equals very poor signal).
• The network needs to have DHCP activated to ensure an IP
address is automatically assigned to the Charge Amps Amp
Guard.
5 Installation
Install the Charge Amps Amp Guard directly after the main
switch of the building to monitor all power usage. For one-phase
installations, L2 and L3 shall not be used.
5.1 Mount Charge Amps Amp Guard
1. Pull the DIN-rail lock downwards and rotate the Charge Amps
Amp Guard onto the DIN-rail.
2. Secure in place by pushing the DIN-rail lock back in place.

13
English
Please note that an additional slot will be needed for the Power
Supply.
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 direction of mounting is marked on the current sensor.
The arrow must point in the current direction.
IMPORTANT!
It is extremely important that the current sensors are connected
to the right phase and are positioned correctly around the main
power cables according to the direction indicators on the clamps.

English
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 connection of the voltage measurement.
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, it will be needed in case voltage measurement
is connected in the future.
IT type networks
Supply networks of IT type is used in parts of Norway, Belgium
and Albania.
In IT network installations, L2 must be connected to both L2
and N. The network type must also be configured, see chapter
Electrical Settings.

IMPORTANT!
• The connection point for the cables should be restricted to an
I²t (let through energy) of a maximum of 10 000 A²s.
• Each phase must be connected to the correct terminal
connector for voltage measurement to function correctly.
1. Turn the power off at the main switch.
2. Connect phases and neutral to the included terminal block.
3. Connect the terminal block to the bottom of the Charge Amps
Amp Guard.
5.4 Mount and connect the Power

English
at the Power Supply, i.e. N to AC(N) (left side) and L1 to AC(L)
(right side).
2. Mount the included 12V power cable to the Power Supply
according to the label at 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.
5. Turn the power on at the main switch.
5.5 Connect the Wi-Fi antenna
1. Mount the included Wi-Fi antenna to the Charge Amps Amp
Guard.
