INSTALLATION 

 

2.1

 

Safety Guidelines 

 

 

 

WARNING 

The following installation instructions are intended for qualified personnel only.  To avoid 

the risk of electrical shock and personal injury, do not perform additional tasks not stated 

in this procedure unless you are qualified to do so. 

 

 

Always adhere to the following safety guidelines: 
 

•

 

Only qualified personnel or 

licensed electricians

 should handle the installation.  Input voltages to 

the DTS SMX can be hazardous. 
 

•

 

Follow all applicable local and national electric codes. 

 

•

 

Verify input voltage and current are within thresholds for the specific DTS SMX model. (See Product 

Specification on page 4) 

 

•

 

Use only UL or ETL listed current transformers.  

ONLY USE CURRENT TRANSFORMERS THAT 

ARE SPECIFIED BY THE MODEL OF DTS SMX.  USE OF ANY OTHER CURRENT 

TRANSFORMER OTHER THAN THE ONE SPECIFIED BY THE DTS MODEL CAN RESULT IN 
PERMANENT DAMAGE TO THE DTS SMX.

 

 

•

 

Ensure that the in-line fuses located on the main board of the DTS SMX are fitted and securely 

fastened. 

 

•

 

Avoid any electrostatic discharge while dealing with any of the internal components of the DTS SMX 

by first touching a grounded structure prior to handling internal components. 

 

•

 

Before applying power make sure that all current transformer and voltage connections are securely 

connected to the main board of the DTS SMX. 

 

•

 

If the DTS SMX is installed incorrectly any built in safety features may no longer be functional. 

 

•

 

Before opening the DTS SMX ensure that all power running to the DTS SMX is removed. 

 

•

 

Under normal operation the DTS SMX should be secured with a 

user supplied lock

 to ensure there 

is no unauthorized access to the live connections in the enclosure.
