1.1  Intended use

The Line Isolation Monitor (LIM) calculates the total hazard 
current in a single phase or three phase isolated power 
system. This is the maximum current that could flow through 
a person who made contact between an isolated conductor 

and ground.
Two seperate ground connections are provided for added safety 
when wiring the LIM into an isolated power system. Each ground 
should be wired individually to the reference grounding bus. A break 
in either connection will cause the LIM to alarm (flashing red LED).
Any other use, or any use beyond the foregoing, is deemed to be 
improper. The BENDER companies shall not be liable for any loss 
and damaging arising therefrom.
Correct use also includes
•    compliance with all instructions from the operating manual
•    adherence to any inspection intervals.
As a basic principle, our “General conditions of Sale and Delivery“ 
shall apply. These are available to the operator not later than the 
time when the contract is concluded.
1.2   Warranty and liability
Warranty and liability claims in the event of injury to persons or 
damage to property are excluded if they can be attributed to one or 
more of the following causes:
•    Improper use of the LIM.
•    Improper assembly/fitting, commissioning, operation and 
     maintenance of the LIM.
•    Failure to take note of the operating instructions concerning 

transportation, commissioning, operation and maintenance of 
the LIM.

•    Unauthorized structural modifications to the LIM.
•    Failure to take note of the technical data.
