Safety instructions
2. Safety instructions
2.1 General safety instructions
Part of the device documentation in addition to this manual is the enclosed "Safety in-
structions for Bender products".
2.2 Work activities on electrical installations.
If the device is used outside the Federal Republic of Germany, the applicable local stand-
ards and regulations must be complied with. The European standard EN 50110 can be
used as a guide.
2.3 Device-specific safety information
Only
qualified personnel
are permitted to carry out the work necessary
to install, commission and run a device or system.
Risk of electrocution due to electric shock!
Touching live parts of the system carries the risk of:
• An electric shock
• Damage to the electrical installation
• Destruction of the device
Before installing and connecting the device, make sure
that the
in-
stallation
has been
de-energised
. Observe the rules for working on elec-
trical installations.
Danger as a result of excessive locating current or excessive locating
voltage!
An excessive locating current of the internal locating current injector may
damage sensitive loads (e.g. control circuits) or trigger unwanted switch-
ing operations. Select a low locating current for these systems. In case of
doubt, please contact our service department.
DANGER
DANGER
Risk of electric shock!
When opening the device, you may come into contact with live parts.
Switch off the mains voltage before opening the device!
Make sure that the basic settings meet the requirements of the IT system.
Persons without the required expertise, in particular children, must not
have access to or contact with the ISOMETER®.
Make sure that the operating voltage is correct!
Prior to insulation and voltage tests, the ISOMETER® must be disconnected
from the IT system for the duration of the test. In order to check the correct
connection of the device, a functional test has to be carried out before start-
ing the system.
In the event of an alarm message of the ISOMETER®, the insulation fault
should be eliminated as quickly as possible.
If the ISOMETER® is installed inside a control cabinet, the insulation fault
message must be audible and/or visible to attract attention.
When using ISOMETER®s in IT systems, make sure that only one active ISO-
METER® is connected in each interconnected system. If IT systems are in-
terconnected via coupling switches, make sure that ISOMETER®s not
currently used are disconnected from the IT system and deactivated. IT
systems coupled via diodes or capacitances may also influence the insu-
lation monitoring process so that a central control of the different ISOME-
TER®s is required.
