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.
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
2.3 Device-specific safety information
Make sure that the basic settings meet the requirements of the IT system.
Children and unauthorised persons 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
ISOMETER® is connected in each interconnected system. If IT systems are
interconnected 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
ISOMETER®s is required.
