Warning: To reduce the risk of injury to the eyes, do not look directly into the
targeting laser and do not point the targeting laser into anyone's eyes.
The instrument is equipped with a class II laser that emits radiation.
Safety regulations:
 Never look directly into the laser beam. The beam and spot can be watched safely from side.
 Make sure that the beam will not be reflected into eyes of people by mirrors or shiny surfaces.

Electrical connection
Follow common safety regulations for mains voltage (230 or 115 V AC) connecting additional devices operat-
ing with this mains voltage (e.g. transformers). Touching mains voltage can be fatal. An incorrect connection
and mounting can cause serious health or material damages.
Only qualified specialists are allowed to connect such devices to the mains voltage.
4 Electrical Installation
The IS 12-TSP or IGA 12-TSP are powered by a voltage of either 24 V (optional 15 to 40 V DC or 12 to 30 V
AC, 48 to 62 Hz. As the instrument is operating with heated and thermostatically controlled sensors, it needs
a warm-up of up to 30 minutes to achieve the maximum accuracy. But directly after connecting to the power
supply the instrument already has a very good accuracy due to the standard temperature compensation. To
switch off the instrument, unplug the connector or interrupt the power supply.
To meet the electromagnetic requirements, a shielded connecting cable must be used. The shield of the
connecting cable has to be connected only on the pyrometer side to avoid ground loops.
LumaSense offers connecting cables, they are not part of standard
scope of delivery. The main connecting cable has wires for power
supply, interface, analog output, external laser switch and external
clear of maximum value storage via contact (see 15, Reference
numbers) and 12 pin angle connector. The cable includes a short
RS232 adapter cable with a 9 pin SUB-D connector for direct PC
communication. This adapter is not used in combination with RS485
interface.
For use of the limit contacts the separate additional cable has to be
used.
