  1. (Optional) Electrical Noise Filter: each unit shall include a high performance EMI/RFI noise rejection filter. Noise attenuation for electric noise shall be as follows using the MIL-STD-220A insertion loss test method.
  1. 41db at 106kHz
  1. Each unit shall provide the following features:
  2. Per phase indicator LED lights, Form “C” dry contacts, surge counter, audible alarm with mute.
  3. Field testable while installed
  4. Enclosure

Enclosure shall be rated UL 50 Type 4 (NEMA 4)powder coated steel.

Part 3—Execution/Installation

3.1Each unit shall be installed per manufacturer’s recommended installation and wiring practices, as shown on the drawing supplied.

3.2Install the SPDs with conductors between suppressor and points of attachment as short and straight as possible. If installed lead length must exceed 10 feet, the SPD manufacturer shall make available a low impedance connection cable for improved installed performance.
