nvent ERICO SES360 Series Instruction Sheet

INSTRUCTION SHEET
SES360 & SES480 Series
Surge Protection Device
WARNINGS
• Safety First - Hazardous Voltage & Shock Hazard
• Only qualified licensed electricians should install or service SPDs
• Hazardous voltages exist within SPDs
• SPDs should never be installed or serviced when energized
• Use appropriate safety precautions including Personal Protection Equipment
• Failure to follow these instructions can result in death, serious injury, and/or equipment damage
• This manual shall be read in its entirety prior to installing
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.
WARNING:
1. nVent products shall be installed and used only as indicated in nVent product instruction sheets and training materials. Instruction sheets are available at
www.nVent.com and from your nVent customer service representative.
2. nVent products must never be used for a purpose other than the purpose for which they were designed or in a manner that exceeds specified load ratings.
3. All instructions must be completely followed to ensure proper and safe installation and performance.
4. Improper installation, misuse, misapplication or other failure to completely follow nVent's instructions and warnings may cause product malfunction, property
damage, serious bodily injury and/or death, and void your warranty.
SAFETY INSTRUCTIONS:
All governing codes and regulations and those required by the job site must be observed.
Always use appropriate safety equipment such as eye protection, hard hat, and gloves as appropriate to the application.
