For measuring purposes only the original PCB
extenders P4LM, P3LL and I9BK, designed to work
with ETL600 equipment, must be used.
The modules in this equipment contain devices,
which can be damaged by electrostatic discharges.
Appropriate measures must be taken before
unpacking modules or withdrawing them from
equipment racks. Essential precautions to prevent
ESD damage when handling or working on modules
are grounding straps for technical personnel and the
provision of anti-static workbenches. Modules may
only be shipped either in their original packing or
installed in equipment racks.
Make sure that the power supply B5LC is
programmed to the correct voltage of 230 VAC or
115 VAC as described in 1KHL015788 before
connecting the equipment to the power source.
Hazardous voltages and/or hazardous energy level
on the module and the cable.
Do not touch the module and the cable leads.
Connecting a load between terminals NO (normally
open) and NC (normally closed) is not allowed.
Use only one contact set NO or NC.
Power supplies connected to alarm relay contacts
must be short circuit and over current protected.
Hazardous voltages and/or hazardous energy level
on the module and the cable.
Do not touch the module and the cable leads.
Connecting a load between terminals NO (normally
open) and NC (normally closed) is not allowed.
Use only one contact set NO or NC.
