Neither removing nor inserting of modules is
permitted during power-up of the equipment.
Preceding to plug in and out of modules the power
supply of the equipment has to be switched OFF.
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
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.
The following assemblies must be removed from the
cabinet and packed separately during transportation:
Power supply unit 115/230VAC B5LC.
The plug-in units must be carefully but firmly
screwed into the racks to prevent them from falling
out. Separately packed modules and other loose
parts must be properly secured and suitably packed
to avoid damage.
The equipment must be mounted in a cabinet.
Cabinets, which are not secured to the floor, tip
forwards when the hinged frame is opened. Do not
open the hinged frame without precautions.
