Installation of the second protective earthing cable
The installation of a second earth cable may be required by the regula-
tions of the country of installation. In making the connection, the following
conditions must be fulfilled:
1. the ground cable must be secured to one of the dedicated connection
points and identified by the symbol
2. use a M6 cable lug .
3. the cable lug must be installed between two toothed washers
4. Secure the cable lug using the screw and the two washers tightening
to a torque of 11Nm.
Residual current protection device
Based on the requirements of the installation country and plant configu
-
ration could it be necessary to install a residual current protection device
to protect the AC line between the inverter and the grid connection point.
The residual current protection device must meet the following characte-
ristics:
PVS-50-TL
PVS-60-TL
Type
A / AC
Sensibility
500mA
600mA
In accordance with article 712.413.1.1.1.2 of Section 712 of IEC Standard 64-8/7, we hereby
declare that, because of their construction, FIMER inverters do not inject ground fault direct
currents.
In the case of systems which consist of several inverters connected to a single switch with
differential protection it is recommended that a device is installed which allows the adjustment
of the tripping value and the tripping time.
Load protection switch (AC disconnect switch)
To protect the AC connection line of the inverter, an overcurrent protec
-
tion device with the following features must be installed:
PVS-50-TL
PVS-60-TL
Type Automatic circuit breaker with differential thermal-magnetic protection
current /voltage rating
100 A / 400 V
100 A / 480 V
Magnetic protection characteristic
B/C
Number of poles
3/4
