5. Mounting and connection

5.1 Mounting

Mount the device using four M5 screws, refer also to the dimension diagram where the
drilling holes are illustrated (see "Dimensions" on page
display can be read during operation and the mains connection is (L1/+, L2/–) positioned
at the top.
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 may be damaged. If several devices
CAUTION are connected, the device does not work and does not signal insulation
faults. Make sure that only one insulation monitoring device is connected.
Heat on the enclosure surface!
The surface temperature of 60 °C can be exceeded under certain operating
conditions.
Keep the cooling slots uncovered by keeping a distance of at least 15 cm
above and at least 10 cm below the device to adjacent objects in order to
ensure constant air circulation.
Risk of injury from sharp-edged terminals!
Risk of lacerations. Touch the enclosure and the terminals with due care.

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.
Risk of electrocution due to electric shock!
Touching live parts of the system carries the risk of:
• An electric shock
DANGER
• 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.

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.
Pluggable push-wire terminals
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.
5.2.2 Step-by-step connection of the ISOMETER®
Connect the device according to the wiring diagram.
Proceed as follows:
1. Connect terminals E and KE to earth (PE)
2. Connect terminals A and B to the BMS bus
3. Connect terminal S to the bus conductor shield
(only at one end of the conductor)
4. Connect terminal L1/+ to L1 of the system to be monitored
5. Connect terminal L2/– to L2 of the system to be monitored
The coupling terminals L1/+ and L2/- are locked. To unplug the terminals,
the orange sliders must be slid towards the front (towards the device) to
unlock the terminal. Now the terminal can be unplugged.
6. Connect terminal A1/A2 to the supply voltage U
7. Connect alarm outputs 11/12/14, 21/22/24 and 31/32/34.
