Reference this wiring diagram as necessary in Steps 2 3 and 4. From the incoming feed connection with an overall length of 1m of wiring including the SPD fuse connection will have a let through voltage of 1500V.
Wiring of the installation and cause damage by considering which device to install.
Spd device wiring diagram. If you want to find the other picture or article about Surge. See Figure 9 – Figure 13. INSTALLATION SHOWN WITH MIDNITE SOLAR E COMBINER BOX.
The conductors used to connect the SPD to the line or bus shall not be any longer than necessary and shall avoid unnecessary bends green wire The following represents a wiring diagram of SPDs in a typical system. A house or building is split into Lightning Protection Zones LPZ as a potential surge passes between one zone to another this is where the appropriate SPD should be fitted eg. The Surge Protection Device SPD is a component of the electrical installation protection system.
Surge protection devices SPD. EN 61643-11 IEC 61643-11 compliance 2. Splice the included Rectorseal RSH60-VMD 24V.
Turn off power to the circuit where surge protector is to be installed. SPD Series type 1 and type 2 units do not require over current protection devices fuses. The following represents a wiring diagram of SPDs in a typical system.
You must refer to this diagram while wiring the SPD. The type 3 surge devices are series wired with dirty as the input from the supply and clean from the SPD to the end equipment it is important to ensure the maximum load current rating of the SPD is not exceeded. When connecting this external TVSS to a typical compact electrical panel it is often not possible to access the bus between the main over-current device and the.
Route the SPD wires through the enclosure hole and mount the SPD enclosure. Appropriate size hole at this location. PV PLUS BUS Red wire BATTERY NEGATIVE black wire GROUND AC IN blackred wire AC OUT blackred wire.

Connect the SPDs neutral wire white to the systems neutral connection not required for 3-phase delta systems 240D 480D and 600D. During a thunderstorm pulsedinterference.
Between the outside LPZ0A to the inside of a building LPZ1 SPD. UL requires the TVSS to be connected on the load side of the main over-current device. The Type 2 SPD is the main protection system for all low voltage electrical installations.
Mount device to keep conductor length as short as possible. Type 2 SPD is characterized by an 820 µs current wave. Pluggable module easy for installation and maintenance.
Cut wires to length and connect to circuit per wiring diagram below avoiding sharp bends or looping. FPV PLUS BUS red wire BATTERY NEGATIVE black wire GROUND green wire AC IN blackred AC OUT blackred wire. Shunt Connected SPD Novaris SD SDD SDN Series Connected SPD Novaris SSP Series Connected Surge Filter Novaris SFH SFM SFD Figure 2 Typical SPD configurations.
SPD connected in parallel has a high impedance. Diagram in Section 23. Connect the SPDs ground wire green to the systems ground connection.
Application wiring diagram operating principle. Select the correct wiring diagram for the SPD you are install-ing. SPD CAN BE USED WITH ANY ELECTRIC PANEL THAT IS WITHIN THE SPD RATINGS.
They are installed in the flaps of various complete sets. Type 1 SPD is characterized by a 10350 µs current wave. Each phase and ensure the correct device is installed.
If it helps consider the installing of SPDs or over voltage devices as you would for fuses or MCBs as over current devices. This device is connected in parallel on the power supply circuit of the loads that it has to protect see Fig. Practical tips for installing surge protection devices in low voltage panel eep what are the requirements domestic dwellings professional electrician china device wiring diagram pdf weidmuller protector spd dc 110v 40ka manufacture arrester din rail class iii protective ovr modular products abb ac 220v lightning 230v single phase 20ka understanding three types of protectors and when to use.
Once the transient overvoltage appears in the system the impedance of the device decreases so surge current is driven through the SPD. Product feature and details 1. Installed in each electrical switchboard it prevents the spread of overvoltages in the electrical installations and protects the loads.
To protect electrical equipment in the house using special devices SPD. Surge Protection Device Wiring Diagram Pdf Surge Protection Device Working Principle Pdf SPD. Three-phase protection for TN-S system 4.
Connect the SPDs phase A B and C wires black to the systems corresponding. Figure 1 Surge protective devices SPDs installed on load side of RCD click to expand scheme In general TT systems require special attention because they normally have higher earth impedances which reduces earth fault currents and increases the disconnection times of Overcurrent Protective Devices OCPDs. The Surge Protection Device SPD is a component of the electrical installation protection system.
Ease of Installation 3. Also they can be observed with a breakdown of the transformer. Surge Protective Devices SPD are used to protect the electrical installation which consists of the consumer unit wiring and accessories from electrical power surges known as transient overvoltages.
It can also be used at all levels of the power supply network.
