– Connect all equipment and accessories
to the equipotential bonding conduc-
tor; see also "Documents for Hazardous
Areas." Each grounding terminal is
marked by a "ground" symbol
Disconnecting equipotential bonding
conductors is not permitted. Make sure
the connection cannot come loose.
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
2
4 mm
and have a suitable ring lug
attached. If the weighing platform is
moved on rollers in a hazardous area,
the speed of movement must be
limited to <1 m/s or the scale must
be grounded.
– Responsibility for ensuring correct and
effective grounding of the equipment
lies with the system operator.
– When using the model EC1XS.-......-L
scale in a hazardous area, make sure
there is no current or voltage in the
equipment before connecting or dis-
connecting current-carrying cables to
or from the scale or system. Disconnect
the system from AC power before
connecting or disconnecting cables.
The specifications (see EC type-exami-
nation certificate) must be taken into
account when connecting accessory
equipment to the platform. See also
.
"Documents for Hazardous Areas."
– Any sockets or ports on the display
and control unit to which no cable is
connected must be protected within
hazardous areas by affixing a cap with
the required IP protection rating.
– Before the EC1XS.-......-L scale is
operated in a hazardous area, it must
be inspected either by a certified
electrician or under the guidance and
supervision of a certified electrician
to make sure that the system complies
with the applicable regulations. Deter-
mine whether the installation must be
registered with the technical inspection
authorities (such as the trade board)
in your country. Regular inspections
must be performed on the system dur-
ing operation. The system should
be inspected at intervals scheduled
to allow for the prevention or early
detection of defects that arise as
a result of normal wear and tear. The
longest permissible interval period is
3 years. Other conditions and standards
that regulate the safety of installation
and operation of the equipment and are
applicable in your country must be met
as well. When performing inspections,
generally acknowledged rules of engi-
neering relevant to these conditions
must be applied.
For the User
– Always make sure the equipment is
disconnected from AC power before
performing any installation, cleaning,
maintenance or repair work on the
scale or weighing system.
– If you see any indication that the
system cannot be operated safely
(for example, due to damage), turn
it off and lock it in a secure place
or otherwise prevent use of the equip-
ment for the time being.
– Chemicals (such as gases or dusts)
that can corrode and damage the inside
or outside of the device must be kept
away from the equipment. Handle
the equipment and accessories in
accordance with the protection (IP)
rating (EN 60529).
– The casing on all connecting cables,
as well as the casing on wires inside the
equipment housing, is made of PVC.
The casing on the power cable is made
of rubber.
– Do not expose the scale to aggressive
chemical vapors or to extreme tempera-
tures, moisture, shocks, or vibration.
The allowable ambient temperature
range during operation is –10°C to
+40°C (14°F to +104°F). Make sure
the place of installation is adequately
ventilated to prevent build-up of
excessive heat.
– If you use cables purchased from
another manufacturer, check the pin
assignments in the cable against those
specified by Minebea Intec before
connecting the cable to Minebea Intec
equipment, and
disconnect any wires that are assigned
differently. The operator shall be solely
responsible for any damage or injuries
that occur when using cables not
supplied by Minebea Intec.
Use only genuine Minebea Intec spare parts.
