Prior to energization of the SPD, it is critical that the 
following items have been addressed. Do not attempt  
to energize the SPD or continue with the installation  
if all these conditions have not been met, or are unknown.

1.  System configuration and voltage

CAUTION

Prior to installation, ensure the system configuration  
and voltage is equivalent to the SPD unit being installed.

Avant l’installation, assurez-vous que la configuration et 
la tension du système sont équivalentes à celles du SPD 
en cours d’installation. 

The SPD model number can be found on the UL label 
affixed to the SPD enclosure. The SPD selection can be 
verified by comparing the model number to the correct 
electrical system described in the “VOLTAGE RATINGS  
AND POWER SOURCE CONFIGURATIONS” chart.

2.  System grounding and bonding 

Verify that an NEC (National Electrical Code) compliant  
X0 bond has been made at the upstream transformer  
or other separately derived system that feeds the SPD. 
Per NEC Article 250.30, this bond must be in place on  
all 3-Phase WYE, 3-Phase Hi-Leg Delta and Single-Phase 
Split-Systems. Refer to diagram "EXAMPLE OF AN NEC 
COMPLIANT GROUNDING ARRANGEMENT FOR A 
SEPERATELY DERIVED SYSTEM" for an example  
of an installation that complies with these NEC 
recommendations.  
 
Verify that there have not been multiple instances  
of neutral-to-ground bonds on the electrical system.  
These bonds, while either intentional or accidental, 
result in ground currents that can create differential 
voltage potentials between neutral and ground.  
Redundant neutral-to-ground connections can result  
in damage to the SPD and are in violation of the NEC. 

Pre-installation requirements

3.  SPD installation on ungrounded power systems  

Ungrounded power 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 that exceed their designed 
ratings. This information is being provided to the user so 
that an informed decision can be made before installing  
any electrical equipment on an ungrounded power system.

4.  SPD location / primary overcurrent protection 

Per the National Electrical Code (NEC Article 285), Type 2 
SPDs are allowed to be placed on the load side of the main 
service breaker/fuse.
