Installation Instructions
Unpacking the Equipment
§
After unpacking the equipment,
please check it immediately for any
visible damage.
$
If you detect any damage, proceed
as directed in the chapter entitled
“Care and Maintenance,” under
“Safety Inspection.”
$
It is a good idea to save the box and all
parts of the packaging until you have
successfully installed your equipment.
Only the original packaging provides
the best protection for shipment.
$
Before packing your equipment, unplug
all connected cables to prevent damage.

Requirements for the Place of
Installation
The weighing platform is designed to
provide reliable results under normal
ambient conditions. When choosing
a location to set up your weighing
platform, observe the following so that
you will be able to work with added
speed and accuracy:
– Set up the weighing platform on
a stable, even surface
– Avoid placing the weighing platform in
close proximity to a heater or otherwise
exposing it to heat or direct sunlight.
– Protect the weighing platform from
drafts that come from open windows
or doors.
– Avoid exposing the weighing platform
to extreme vibrations during weighing.
– Protect the weighing platform from
aggressive chemical vapors.
– Do not expose the weighing platform
to extreme moisture over long periods.
Turn off the power when the weighing
system is not in use.
Conditioning the Weighing Platform
Moisture in the air can condense on
the surface of a cold weighing platform
whenever it is brought to a substantially
warmer place. If you transfer the weigh-
ing platform to a warmer area, make
sure to condition it for about 2 hours at
room temperature, leaving it unplugged
from AC power. Afterwards, if you keep
the weighing platform connected to AC
power, the constant positive difference
in temperature between the inside of
the weighing platform and the outside
will practically rule out the effects of
moisture condensation.
§
Prepare a suitable place of installation
for the weighing platform. The place
of installation should be dry, level
and even. The allowable operating
temperature range is 0°C to +40°C
(32°F to 104°F).
§
If the weighing platform is in a
hazardous area/location, it must
be grounded (i.e., an equipotential
bonding conductor must be connected).
This connection must be made by a
trained technician. All IS...-.X weighing
platforms are equipped with a terminal
for connecting the grounding con-
ductor. The grounding conductor is
connected to a threaded bolt or terminal
screw, or a bore hole is provided. If a
bore hole is provided, use a stainless
steel screw and nut to connect the
grounding conductor. Use of a tooth
lock washer is recommended to prevent
the screw from coming loose. The wire
used for the grounding conductor
should have a cross-sectional diameter
of at least 4 mm 2 , with a suitable ring
lug attached. Connect all equipment,
including peripheral devices, to the
equipotential bonding conductor.
When connecting the platform to
the indicator (for models IS16EDE-HX,
IS34EDE-HX, IS64-EDE-SX,
IS150IGG-HX, IS300IGG-HX), use only
cabling and extensions approved by
Minebea Intec, as these are made in
accordance with the restrictions on
permis sible cable lengths imposed by
both the capacitance and inductivity
values (see the “Schedule to EC Type-
Examination Certificate” in the operat-
ing instructions) and the requirements
for electromagnetic compatibility.Before
putting the weighing system into oper-
ation for the first time, make sure there
is no hazard of explosion present at the
place of installation.
If there is any indication that the equip-
ment does not function properly (e.g.,
display remains blank, or no display
backlighting) due to damage during
transport, disconnect the equipment
from power and notify your nearest
Minebea Intec Service Center. The
specifications for Ui, Li, Pi, Ta, tem-
perature class, Ci, and Li for IS...-.X
weighing platforms are listed in the EC
type-examination certificate. The EC
type-examination certificate also speci-
fies which accessories are permitted for
connection. These specifications must
be taken into account when connecting
accessory equipment to the platform.
The explosion-protected weighing plat-
form must be set up in accordance with
acknowledged technological standards.
These include the national laws and
regulations applicable at the place
of use. In particular, the conditions
described under Item 17 of the KEMA
EC type-examination certificate,
“Special Conditions for Safe Use,” must
be observed. Furthermore, national
regulations for accident prevention
and environmental protection must
be observed at all times.
Before the weighing system is operated
in a hazardous area/location, it must be
inspected either by a certified electrician
or under the guidance and supervision
of a certified electrician to make sure
that the weighing system complies with
the applicable regulations (in Germany,
Section 12 of the ElexV). Determine
whether the installation must be
registered with technical inspection
authorities (such as the trade board)
in your country. Observe all safety
instructions. Regular inspections
must also be performed on the system
during operation. The system should
be inspected at intervals scheduled to
allow for the prevention or early detec-
tion of defects that arise as a result of
normal wear and tear. The longest
permissible interval period is 3 years.
Make sure all relevant conditions are
met when installing the equipment and
during operation (for example, condi-
tions imposed by an employers’ liability
insurance association). When perform-
ing inspections, generally acknowledged
rules of engineering relevant to these
conditions must also be applied.
If the equipment housing is opened by
anyone other than persons authorized
by Minebea Intec, or if the equipment
is installed or operated incorrectly, this
will result in forfeiture of the approval
for use in the stated hazardous area(s)/
location(s) and of all claims under the
manufacturer’s warranty.
