This manual provides guidelines for the proper installation of the CurrentGuard 

Compact (CGC) devices . Proper product selection and compliance with these 

guidelines will help your new suppression system provide years of reliable 

service . If installers are unsure about the facility electrical configuration or have 

other installation-related questions, it is recommended they consult with a master 

electrician or other qualified electrical professional .

When shortcuts are taken or installation procedures are not followed, the 

CurrentGuard system may be damaged or may not provide adequate protection .  

It is extremely important to follow these installation procedures carefully .

warranty is voided if the unit is damaged as a result 

of improper installation or the installer’s failure to verify the following 

conditions prior to installation.

 

W A R N I N G ! 

HAZARDOUS VOLTAGES PRESENT:   Improper installation or 

misapplication may result in serious personal injury/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).

IMPORTANT SAFETY INSTRUCTIONS:   All work must be performed 

by licensed and qualified personnel. The electrical system must be 

properly grounded in accordance with the U.S. National Electrical Code, 

state and local codes or other applicable codes for this SPD to function 

properly. Do not connect CurrentGuard device to the line side of the 

main service breaker or disconnecting means. This device is suitable 

for installation where the available short circuit current is 200,000 rms 

symmetrical amperes up to 600VAC or less.

 

W A R N I N G !    

Check to ensure that a proper bond is installed between neutral and 

ground at the transformer upstream from the CurrentGuard device (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 CurrentGuard and void the warranty.
