1. DESCRIPTION, INSTALLATION
1.1 Description
Type 2 SPDs for photovoltaic (PV) installations with voltages which may
reach a maximum voltage (Uocmax) of 1200 VDC (irrespective of the
local environmental, temperature, sunlight conditions, etc).
Specifically designed to protect the DC part of PV installations (PV
panels and inverters)
- based on the use of non-polarised panels (panels which do not require
their active conductors to be earthed)*
- without an energy storage system (e.g. batteries, etc)
Equipped with replacement plug-in modules with LED indicators (red
LED: modules need to be replaced).
* equipped with status feedback
1.2 Installation
SPDs must not be installed in locations where there is a risk of fire or
explosion without special precautions. They must be disconnected
before checking the installation insulation resistance.
Connections as per section 4.5 and 4.6: SPD connected to the mains
supply and to the protective conductor (PE) using as short a connection
as possible (< 50 cm).
Electromagnetic compatibility rules: avoid loops, fix the cables firmly
against the exposed metal conductive parts.
Compulsory connection of the earth terminal on the SPD to the
protective conductor (PE) in the distribution board.
Equipotentiality rules: interconnection of the exposed conductive parts
of the equipment and the protective conductor (PE) in the distribution
board, which is itself connected to the earth terminal of the SPD (see 4.6).
