TPS4 13 Installation Instructions
Bonding and Grounding Hazard
Verify that the neutral conductor in the service entrance equipment is bonded to ground in accordance with
the National Electric Code (NEC®) and all applicable codes. During installation into an electrical system the
SPD must not be energized until the electrical system is completely installed, inspected and tested. All
conductors must be connected and functional including the neutral (if required). The voltage rating of the
SPD and system must be verified before energizing the SPD. Failure to follow these guidelines can lead to
abnormally high voltages at the SPD. This may cause the SPD to fail. The warranty is voided if the SPD is
incorrectly installed and/or if the neutral conductor in the service entrance equipment or downstream of
separately derived systems is not bonded to ground in accordance with the NEC®..
Do Not Hi-Pot Test SPDs
Any factory or on-site testing of power distribution equipment that exceeds normal operating voltage such
as high-potential insulation testing, or any other tests where the suppression components will be subjected
to higher voltage than their rated Maximum Continuous Operating Voltage (MCOV) must be conducted with
the SPD disconnected from the power source. For 4-wire systems, the neutral connection at the SPD must
also be disconnected prior to performing high-potential testing. Failure to disconnect SPD and associated
components during elevated voltage testing will damage the SPD and will void the warranty..
SPDs on Ungrounded Systems
Caution – Ungrounded systems are inherently unstable and can produce excessively high line-to-ground
voltages during certain fault conditions. During these fault conditions, any electrical equipment including
an SPD may be subjected to voltages which exceed their designed ratings. An SPD designed specifically for
Ungrounded systems should be used..
Unpacking and Preliminary Inspection
Inspect the entire shipping container for damage or signs of mishandling. Remove the packing materials and
further inspect the unit for any obvious shipping damages. If any damage was found and is a result of
shipping or handling, immediately file a claim with the shipping company and forward a copy to
Raycap. SalesSupport@Raycap.com
Storage Environment
This SPD should be stored in a clean, dry environment. Storage temperature range is -35°C (-31°F) to +75°C
(+167°F). Avoid exposure to high condensation.
