1 JuiceMeter
JuiceMeter is an energy meter that communicates with your JuiceBox to enable the Load
Optimization Pro feature.
After pairing the two devices, JuiceMeter allows your JuiceBox to adapt its power level based
on the consumption of other devices connected to the same power line. In this way, you can
recharge at the maximum available power while avoiding the risk of triggering the meter.
The JuiceMeter is available in single-phase and three-phase versions. Both products are
available in standard and IT GRID compatible versions depending on the type of installation.

1. Read the Safety Warnings manual inside the packaging.
2. Install the product in an electrical cabinet that is accessible only to qualified personnel.
3. Din rail mounting.
>The product must be installed in a vertical position on a 35mm DIN rail, with the screw
terminal facing downwards.
>Leave at least 30mm of space above and below the JuiceMeter, and at least 10mm of
space to the right and left of the product in relation to adjacent DIN modules, to ensure
proper heat dissipation.
>It is not recommended to install the product close to heat sources. If necessary, maintain
adequate distance between the JuiceMeter and such heat sources.

>Use PVC-insulated wires able to withstand temperatures of at least 80 °C. Such as
H05V2-K, AWM Style 1007, or equivalent.
>Ensure that all stranded wires are inserted into the screw terminal to ensure good
contact.

THREE-PHASE measurement method: with "split core" current transformers for measuring
current, to be connected with the black wires in common on terminal "Com" and the white
wires on the respective terminals "Ir", "Is" and "It" as shown in the wiring diagram.
The voltage is measured across terminals “R” and “N”, “S” and “N”, “T” and “N”. The latter pair
is also used for the single-phase power supply of the device.
Current transformers: to be installed on the three-phase cables, as shown in the wiring
diagram below. Pay attention to the "K → L" marking on the transformers.
Pay attention to the terminals for connecting the current transformers, which are referred
to the primary circuit. The current transformers must be wired and used inside the electrical
panel that must guarantee insulation for users.
