Strider M72 

ME-PM-M72

It is good practice to install sensitive electronic instruments that are performing critical functions in EMC enclosures that protect against electrical 
interference causing a disturbance in function. Warning  

• 

During normal operation, voltages hazardous to life may be present at some of the terminals of this unit. Installation and servicing should be 
performed only by qualified, properly trained personnel abiding by local regulations. Ensure all supplies are de-energized before attempting 
connection or other procedures.

• 

Terminals should not be user accessible after installation and external installation provisions must be sufficient to prevent hazards under fault 
conditions.

• 

This unit is not intended to function as part of a system providing the sole means of fault protection - good engineering practice dictates that 
any critical function be protected by at least two independent and diverse means.

• 

The unit does not have internal fuses therefore external fuses must be used for protection and safety under fault conditions.

• 

Never open-circuit the secondary winding of an energized current transformer.

• 

If this equipment is used in a manner not specified by the manufacturer, protection provided by the equipment may be impaired.

Auxiliary circuits (communication & relay outputs) are separated from metering inputs and 110-400V auxiliary circuits by at least basic insulation. 
Such auxiliary circuit terminals are only suitable for connection to equipment which has no user accessible live parts. The insulation for such auxil-
iary circuits must be rated for the highest voltage connected to the instrument and suitable for single fault condition. The connection at the remote 
end of such auxiliary circuits should not be accessible in normal use. Depending on application, equipment connected to auxiliary circuits may vary 
widely.
