Installation
W A R N I N G
Potential Electrocution Hazard. Only qualified personnel should conduct the tasks described in this
section of the manual.
C A U T I O N
Possible danger to sensor or logger. Always disconnect power to the instrument when making any
electrical connections.
Install the RTC module
Only install RTC DIN rail versions on a DIN rail. Only install an IPC panel mount versions according
to the IPC manufacturer specifications that are supplied with the hardware.
Attach the module horizontally. Make sure that the passive aeration element operates correctly.
Make sure that there is a minimum of 30 mm (1.2 in.) of space around the module.
To use the RTC module indoors, install the module in a control cabinet. To use the RTC module
outdoors, install the module in an enclosure. Refer to
Specifications on page 3 for the enclosure
specifications.
An sc1000 controller is necessary to operate the RTC module. Refer to the sc1000 controller
documentation. It is necessary to use software version V2.30 (or higher) for the sc1000 controller.
Hardware is subject to change without notice. Refer to the sc1000 documentation and other
hardware documentation for input/output electrical wiring. Additional information of RTC controllers
and setting parameters is available on the manufacturer's website.
This instrument is rated for an altitude of 2000 m (6562 ft) maximum. Use of this instrument at an
altitude higher than 2000 m can slightly increase the potential for the electrical insulation to break
down, which can result in an electric shock hazard. The manufacturer recommends that users with
concerns contact technical support.
Supply power to the RTC module
D A N G E R
Electrocution hazard. Do not connect AC power directly to a DC powered instrument.
An external deactivation switch is necessary for all installations. Refer to Table 1 .
Table 1 Supply voltage of the RTC module
Specification Description
Voltage 24 V DC (-15%/+20%), maximal 25 W
Recommended fuse C2
With 110–240 V option 240 V, 50–60 Hz, approximately 25 VA
Connect to the process instruments
The measurement signals of the sc sensors are supplied to the RTC module through the RTC
communication card in the sc1000. For information about the power supply of the sc1000 controller
and the sc sensors, refer to the applicable documentation for the sc1000 controller and sc sensors.
