4.13.3 TO INSTALL THE LOAD INTERFACE IN AN
ELECTRICAL CABINET
This is a general instruction of the load interface
installation. The load interface is intended to act as an
interface to the power and current meters as input to the
DLM system of GARO Entity charging stations. The
procedure differs between different installations and
can also differ due to national regulations. The load
interface unit is designed for DIN rail mounting. Two
different load interface units are available at GARO:
GARO Entity Balance basic and GARO Entity Balance
advanced.
NOTE
This chapter shows the installation of the GARO Entity
Balance BASIC model. The process for the GARO Entity
Balance ADVANCED is similar. If the group contains
local production (like PV/solar panels) with a net output
power that can get close to the max. current, then a
separate energy meter for bidirectional power is
required. Only current transformers (CT) are not
capable to detect power direction.
1. Turn the power/voltage off by an appropriate
insulating main switch.
2. Make sure that the power/voltage is off.
3. Install an insulating and protection device (RCBO or
MCB) on a DIN rail (A). The load interface normally
requires an individual insulating and protection
device for 230 V. For this purpose it is
recommended to use a 2–pole 2–10 A RCBO.
