1. Safety Information

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.

1.5 Hazards when handling the Line Isolation Monitor

LIM2000-1, LIM2000-1CB and LIM2000-3CB
The LIM is constructed according to state of the art and the

recognised safety engineering rules. Nevertheless, when it is

6

being used, hazards may occur to the life and limb of the user or of
third parties, or there may be adverse effects on the LIM or on other

valuable property. The LIM must only be used

• for the purpose for which it is intended

• when it is in perfect technical condition as far as safety is

concerned
Any faults which may impair safety must be eliminated immediately.

Impermissible modifications and the use of spare parts and
additional devices which are not sold or recommended by the
manufacturer of the LIM may cause fire, electric shocks and

injuries.
Unauthorized persons must not have access to or contact

with the LIM.

against dust and moisture, and spraying or dripping water, and
where the indicated storage temperatures are maintained.

Please check for correct system and supply voltage !
When insulation and voltage tests are to be carried out, the device

must be isolated from the system for the test period.
In order to check the proper connection of the LIM, it is

recommended to carry out a functional test, before starting the LIM.
Please check whether the basic setting of the devices complies with

the system requirements.
Children or the public must not have access to the LIM.
