Creating Equipotential Bonding - Kaco blueplanet 87.0 TL3 M1 WM OD IIF0 Manual

7 | Installation
Install RS485 surge protection
↻ It has been ensured that there is no AC/DC voltage present.
↻ Device open [ [See section 7.2} Page 22]].
. NOTE: Clamp RS485 base element for surge protection at the in-
tended position in accordance with the drawing onto the top hat rail
from bottom to top.
1. The following colour coding must be observed for the internal/external RS485
cable:
Data A => white (WH); Data B => blue (BU); GND => violet (VT)
2. The internal RS485 cable is to be connected to the overvoltage socket on the
socket. [See installation instructions in the [See section 4.4} Page 15] package]
. NOTE: For inlet/outlet on the RS485 externally, the surge protection
socket outlet is to be assigned twice.
3. Insert RS485 cable through the interface cable fitting and into the connection
area.
4. Strip the RS485 cable [approx. 20 mm] and remove the insulation from the indi-
vidual wires [8 mm].
5. Fit wire end sleeves onto the wires and connect them to the RS485 base ele-
ment in accordance with the wiring diagram [ S_M3 /
6. Connect the output cable with RS485 plug (included with the overvoltage kit) to
the RS485 base element and insert the RS485 plug into the RS485 socket on the
communication board.
7. Fix the output cable to the cable guide.
8. Insert RS485 overvoltage protection module into the base socket.
9. Ensure that the protective elements are properly secured.
ð Proceed with the installation of the protective elements.
Installing the Ethernet surge protection
↻ It has been ensured that there is no AC/DC voltage present.
1. Clip the Ethernet overvoltage protection module into the top-hat rail top end
first.
2. Connect the short Ethernet cable with an Ethernet port on the communication
board. [See installation instructions in the [See section 4.4} Page 15] package]
3. Route the Ethernet cable through the cable fitting provided and insert it into the
overvoltage protection module.
4. Fix Ethernet cable on cable guide and tighten cable fitting [ W_29/
In-Ibs ].[ W_29/ 2.5 Nm].
ð Proceed with the installation of the device.
