BEFORE INST LL TION WARNING: HAZARDOUS VOLTAGES PRESENT Improper installation or misapplication may result in serious personnel injury and/or damage to electrical system. Read the complete installation instructions before proceeding with installation. Remove all power to the electrical panel before installing or servicing the surge protective device (SPD).
WARNING: Check to ensure that a proper bond is installed between neutral and ground at the transformer upstream from all 3-phase WYE, 3-phase high leg DELTA or split-phase ServiceTrack ST SPD (See NEC Article 250). If the transformer is not accessible, check the main service disconnect/panel for the N-G bond. Lack of a proper bond will damage ServiceTrack ST and void the warranty.
One or two twists or braids of all conductors per foot and securely tie-wrap when conductor lengths must exceed 12”. 5. Conductor Sizing Total Protection Solutions recommends installing ServiceTrack ST by using the following conductor size for phase, ground and neutral connections. Braiding or twisting conductors together using tie-wraps or electrical tape increases the protection performance of the device.

6. Conduit Openings The 80kA unit comes with a 3/4” conduit hub. This hub requires a 1- 1/8” diameter hole for proper installation. Note the hub supplied with the unit, when properly installed, ensures the enclosure maintains its NEMA 4 rating. The 120kA to 400kA units come with a 1”conduit hub.
Install SPD directly adjacent to the point of termination to insure conductor length is as short as possible for optimum performance and protection. 2. Connecting Form C Dry Contacts All ServiceTrack ST units come standard with one set of Form “C” dry relay contacts for the surge protective device status. These contacts are for connection to a user-provided remote alarm and monitoring circuit.
3. Neutral to Ground Filter Jumper All ServiceTrack ST models with enhanced transient filter, “-F” suffix, (which have a neutral connection) come with a green jumper wire, which loops out of the epoxy and connects the filter from neutral to ground. In certain medical applications or circuits which employ or contain Ground Fault Circuit Interrupting protection, this Neutral to Ground filter connection should be removed to avoid any nuisance tripping the breaker.
