INSTALLATION
Important:
To avoid damage to the SCU and to the sensor cable, disconnect the
power cable before adding or removing cables or printed circuit boards.
Connections may only be made while the unit is
switched off
.
4.1
SENSOR CABLE
Humidity:
The sensor cable must always be protected from humidity, i.e. the
cable ends must be sealed while storing or mounting the cable.
Bending:
The minimum bending radius of the sensor cable is 25 cm. This limit
must be adhered to at all times.
I
nstallation temperature:
Installation of the sensor cable
may not
take place at
temperatures below +10 °C (45 °F).
Protection caps:
Sensor cables are delivered with ESD-protection or protection
caps (
5 SENSOR CABLE CONNECTIONS), depending on the connection type.
This protection may not be removed until the connection of the sensor cable takes
place.
ESD-protection:
ESD-protection-cap
Heatshrink
Sensor cable
Prefabricated sensor cables must be installed, so that the red ESD-protection-cap is situated at the
SCU 800 or the connection box. The ESD-protection-cap also protects the crimp- and shield-connectors.
Sensor cable delivered on cable spools always has the ESD-protection on the innermost sensor cable
winding.
A short-circuit connector is mounted under the ESD-protection-cap.
Fixings:
Various fixings, e.g. self-locking clamps, cable ties, pipe brackets, etc., may be used to install the sensor
cable, so that project requirements are met. Overview 60V082 shows various possibilities, that can be
supplied by LISTEC.
Distance between fixings
recommended: 0,75 m
maximum:
1,0 m
First fixing after connection box:
ca. 30 cm
Fixing next to end caps:
ca. 10 cm
Note:
Local authorities may have special regulations regarding the mounting of
equipment on ceilings.
