1.0 Introduction The SolaHD STV200/400K Series surge protective devices (SPDs) offer continuous protection from electrical noise and high-impulse, potentially damaging transients commonly found at the service entrance or distribution panel. The modular, robust design provides installation flexibility, while allowing placement in the most severe exposure locations. Proper installation is required for maximum system performance.
3.0 Preinstallation 3.1 Unpacking & Preliminary Inspection 1. Inspect the shipping crate(s) for damage or signs of mishandling before unpacking the unit. 2. Remove any securing bands and cardboard packing and inspect the unit for any obvious shipping damage. 3. If any shipping damage is observed, immediately file a claim with the shipping agency and forward a copy to your SolaHD Representative. 3.2 Storage The unit should be stored in a clean, dry environment.
3.4 Electrical Connections ! Danger! Verify that all power circuits are de-energized and locked out before making electrical connections. All electrical connections must be installed by a licensed electrician and all wiring must comply with the National Electrical Code (NEC) and applicable local codes. 3.
3.6 Parallel Connection To reduce the wiring impedance to surge currents, it is recommended that the phase, neutral (if required), and ground conductors are twisted together and routed in the same raceway (conduit). Avoid any sharp bends in the conductors. Tip: To maximize system performance, locate the unit as close as possible to the protected circuit and keep interconnecting wiring less than 5 feet.
Neutral Phases Ground To Protected Loads Neutral Rotary Disconnect Phase(s) SolaHD Surge Protective Device Transient Ground Protected Panel Wire should be less than 5 feet and as straight as possible Safety Ground Figure 2: Typical parallel connection with internal rotary disconnect Voltage Protection Ratings (VPRs): To obtain the Voltage Protection Ratings (VPRs) as obtained by Underwriters Laboratories, Incorporated, in accordance with ANSI/UL 1449 Third Edition, the Standard for Safety, Surge
A) Installation. Type 1 SPDs (surge arresters) shall be installed as follows: 1) Type 1 SPDs (surge arresters) shall be permitted to be connected to the supply side of the service disconnect as permitted in 230.82(4) or 2) Type 1 SPDs (surge arresters) shall be permitted to be connected as specified in 285.24. B) At the Service.
3.9 SPD Monitoring External Status Indicators: These indicators provide a summary of the status of the SPD module. For normal conditions, the green “OK” LED is illuminated and the red “Service” LED is off. If the SPD module requires replacement, the green “OK” LED is turned off and the red “Service” LED is illuminated. Summary Alarm Contact: Summary alarm Form C relay contacts are provided for remote indication of a failed SPD module. Contacts are rated 5 A at 250 V ac maximum with a power factor of 1.0.
1) Taps Not Over 3 m (10 ft.) Long. If the length of the tap conductors does not exceed 3 m (10 ft.) and the tap conductors comply with all of the following: 1) The ampacity of the tap conductors (25 A in our case) is a. Not less than the combined calculated loads on the circuits supplied by the tap conductors, and b. Not less than the rating of the device supplied by the tap conductors or not less than the rating of the overcurrent protective device at the termination of the tap conductors.
4.0 Installation 1. Ensure that all power is removed before beginning installation. A qualified, licensed electrician shall install all electrical connections. 2. The STV200/400K is provided in a UL Listed Type/NEMA 12 enclosure which is suitable for indoor installations. Optional UL Listed Type/NEMA 3R, 4 or 4X enclosures are suitable for indoor or outdoor applications. 3. Determine the mounting location.

7.0 Maintenance & Service ! danger! Only qualified personnel should perform maintenance on this system. Hazardous voltages are present inside the unit during normal operation. Electrical safety precautions must be followed when servicing this unit. To prevent risk of electrical shock, turn off and lock out all power sources to the unit before servicing. 7.
8.0 Troubleshooting If status failure indication occurs or Form C relay has changed states, a licensed electrician shall first determine if the system’s voltage and proper phasing exists. If it remains in an alarm condition once the electrician is satisfied that the electrical system and its connections are normal, the unit should be repaired.
