Page 5: Introduction
Introduction Give your pyranometers the protection they deserve! SPD01 is a surge protection device for digital pyranometers communicating over RS-485. The SPD01 reduces the risk of costly instrument damage and data loss, by serving as an additional layer of external protection against high-impulse currents and voltages - surges- for connected devices. - Page 6 Immunity to high impulse voltages and currents - surges SPD01 is a surge protection device for pyranometers. It is designed for use with the Hukseflux-brand “industrial pyranometer” series of instruments. The device combines and coordinates the protection of the power supply and the RS-485 serial communication lines.
- Page 7 • SPD01, sacrificial device SPD01 is built to last. It will survive multiple surges. It is a sacrificial device. In case SPD01 the most likely failure mode is: - that communication with the protected pyranometers through the SPD01 is no longer...
- Page 8 2 (LPZ2) as defined in IEC 62305-4:2010 section 4.3. At each zone boundary an SPD of the correct type should be installed. This is indicated in Figure 0.2. For example, the Hukseflux SPD01 is a type 2 SPD which is used on the zone boundary from LPZ0b to LPZ2.

Pyranometer insulation disk 2.5.1 SMF01 SMF01 is a practical metal bracket that helps mounting a surge protection device SPD01 on a vertical mast. It comes with mounting screws and two tube clamps (40-60 mm). • tube mounting bracket, with mounting screws •... - Page 14 Figure 2.5.1.2 The SMF01, set of parts. 2.5.2 PID01, electrical isolation Hukseflux industrial pyranometers may be safely installed directly onto a PV array. The electrical potential of the array support structure may be affected by, for example fault currents and lightning strikes. Therefore special care should be taken to potential differences that may be present in different parts of the PV plant installation.

3 Installation of SPD01 3.1 Wiring Diagram SPD01 can be used to protect up to three digital pyranometers and provides a terminal to extend the databus. Five cable glands provide access to the internal screw terminals. The two unprotected screw terminals (and cable glands) are used to connect long (>... -
Page 16: Gland Connections
3.2 Gland connections SPD01 is made out of a plastic enclosure with metal cable glands. The metal cable glands are part of the electrical structure of the SPD01 and form an electrical connection between the cable shield and earth ground. The cable shield should be connected to the cable gland housing. - Page 17 Connect the earthing terminal to earth ground to guarantee personal safety When Hukseflux industrial pyranometers and SPD01 are directly connected to a SCADA system the earthing terminal of the pyranometer and SPD01 should be connected to earth as well as the SCADA system enclosure earth ground to realise equipotential bonding.

Page 18: Installation Of Optional Mounts
The optional mounting fixture, for simplified mounting of SPD01 on a pole or tube, is easy to use. It can be fitted to SPD01 using the mount’s M4 bolts and a 4 mm hex key. The SMF01 with SPD01 can be clamped on a (40 to 60 mm diameter) tube or pole with the included tube clamps using a flat head screwdriver or a 7 mm hex nut driver. -

Alternatively, another SPD with appropriate specifications can be used to protect the • instrument. The length of each cable connecting an instrument to SPD01 should be kept as short • as possible and should never exceed 3 meters (10 ft). - Page 20 Figure 3.5.1.1 Example of single instrument installation. Cabling from SPD01 to the SCADA system can be extended to an arbitrary length not exceeding the maximum length allowed for RS-485 systems, see Figure 3.5.1.2. In practice 100 meters (328 ft) is an economical, safe, and reliable maximum to work with.
- Page 21 The cable shield between SPD01 and the SCADA system may or may not be connected, depending on the grounding strategy and the general installation design.
