Installation and connection
5. Installation and connection
5.1 Installation
Install the device using four M5 screws, also refer to the dimension diagram on
where the drilling holes are illustrated. Install the device so that it is in a vertical position
with the system coupling (L+, L–) positioned at the top when it is being operated. All di-
mensions in mm.
5.2 Connection
5.2.1 Connection requirements
Only
qualified personnel
are permitted to carry out the work necessary
to install, commission and run a device or system.
DANGER
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.
WARNING
Warning of insulation monitoring devices that do not work correct-
ly!
Connect the terminals KE and E individually to the protective earth con-
ductor PE.
CAUTION
Risk of injury from sharp-edged terminals!
Risk of lacerations. Touch the enclosure and the terminals with due care.
CAUTION
Risk of property damage due to unprofessional installation!
If more than one insulation monitoring device is connected to a conduc-
tively connected system, the system can be damaged. If several devices
are connected, the device does not work and does not signal insulation
faults. Make sure that only one insulation monitoring device is connected
in each conductively connected system.
Ensure disconnection from the IT system!
When insulation or voltage tests are to be carried out, the device must be
isolated from the system for the test period. Otherwise the device may be
damaged.
Check proper connection!
Prior to commissioning of the installation, check that the device has been
properly connected and check the device functions. Perform a functional
test using an earth fault via a suitable resistance.
All terminals are pluggable push-wire terminals. Solid connecting wires
can be directly plugged in. For connection of flexible cables, the push-wire
terminals must be pushed open by pressing the corresponding orange in-
terlocking mechanism with a flat-head screwdriver.
