1.0 Installation The SolaHD STV100K Series Surge Protective Device is a high-quality, highenergy surge current diversion system designed to protect sensitive equipment from damaging transient voltage surges resulting from load switching, lightning strikes, and other sources. The installer should perform the following steps to ensure a quality installation. Please read all instructions before starting the installation of this product. These instructions do not replace national or local electrical codes.
1.4 Mechanical Dimensions Figure 1: Mechanical Dimensions (in.) Unit shown is a three-phase wye 1.5 Voltage Protection Ratings (VPRs) To maintain the voltage protection ratings marked on these products, as obtained by Underwriters Laboratories, Inc. in accordance with ANSI/UL 1449, 3rd edition, the Standard for Safety, Surge Protective Devices (SPDs), #12 AWG wire must be utilized to connect the STV100K Series to your facility’s power grid.
1.8 Wiring Connections Before making connections to the unit, verify that the unit model number and nameplate voltage rating are appropriate for connection to the intended power source. See Table 1 for voltage rating applications with typical power source configurations. 1. Connect the black phase wires to the corresponding phase on the service panel. For delta high leg units, ensure the high leg is connected to Phase B of the SPD. 2.
