Installation
Explosion hazard due to improper installation !
Non-compliance may result in fatal or serious injuries.
Ensure the atmosphere is non-explosive.
Make sure that the device is not damaged.
If the device is connected to the mains:
o
Disconnect the device from the power supply.
o
Isolate supply and all Ex e circuits and wait 5 minutes before
opening the terminal boxes.
Danger of laser radiation at emitting diode (TD-A, TD-B) or at
the end of the fibre optic cable.
Eye injury
The laser diodes in the Exicom operating devices, media converters
and switches emit invisible laser radiation:
100Base-FX
- 1300 nm
FO-MM / 1000Base-SX
-
770 … 860 nm
FO-SM / 1000Base-LX
-
1270 … 1355 nm
According to EN 60825-1, the laser diode is assigned to the laser
class 1M.
Do not view the laser radiation directly (within a distance of
100 mm) with optical instruments (e.g. magnifiers, microscopes).
Explosion hazard due to electrostatic charg e!
Do not apply protective foil to touch display.
8.5.1
General information on electric connection
Connect cables carefully.
Do not screw down on the cable insulation.
Do not switch cables.
Observe code of practice when connecting cables.
Firmly screw down wires.
Pay attention to the voltage specified on the device:
o
Connect DC devices to 24 VDC only.
o
Connect AC devices to 100 to 240 VAC only.
Pay attention to specified torques for screws to avoid damage to threads.
Suitable measures against electrical surge during lightning strike may be necessary.
8.5.2
Connecting device to power supply
1. Open the cover of the Ex e terminal box (see chapter
2. Connect cable to terminal X1 POWER (see chapter
19.1 Connection overview terminal
). Ensure correct polarity and power supply (AC or DC).
