2.12 Safety Instructions Concerning Installation and Operation
of the Device
− Do not expose the scale, the ex-link converter, the power supply, or the
accessories supplied by Sartorius to extreme temperatures, aggressive chemical
vapors, moisture, shocks, vibrations, or strong electromagnetic fields. Observe the
conditions of operation described in the Specifications.
The connection cables between the devices as well as the casing on the wires
inside the device housing are made of PVC. Chemicals that corrode this material
must be kept away from these cables.
− Note the IP protection rating of the scale, the ex-link converter, and the power
supply. Do not allow liquid penetration. The protection class specifies the
suitability of equipment for various environmental conditions (moisture, foreign
bodies).
− The scale and ex-link converter may only be opened by Sartorius Service with the
power disconnected. Do not open the power supply.
− Avoid generating static electricity on the glass panel of the operating display and
plastic casing.
− The YEPS01-USB power supply for the ex-link converter may only be connected
to supply voltages of min. 90 V and max. 264 V at a frequency of 48–62 Hz.
− Observe connection data (see Chapter "15.1 General Data", page
− The equipment must only be used indoors. Connect the scale and the ex-link
converter YCO17-Z to the equipotential bonding conductor using a suitable low
resistance method. All electrical circuits are grounded and electrically connected
to the metal parts of the devices. The equipotential bonding conductor of the
devices must be connected properly, according to commonly accepted technical
standards.
− The installation must be checked for correct function and safety by trained
and qualified personnel at appropriate intervals (e.g., checking the cables for
damage).
− Operating personnel must be trained to recognize faulty operating states and to
be able to initiate the necessary safety measures (e.g., disconnecting the ex-link
converter from the power supply).
− Lay the cables where they pose no risk of causing someone to trip.
Never close a paint can using a hammer while it is still on the weighing pan.
When closing, place the paint can on a firm, stable surface.
Observe the additional safety precautions and hazard warnings in subsequent
chapters.
