1. Safety instructions, intended use
a.) The height adjustability of the undercarriage serves for the electrically operated adjustment of an individual
working height for the optionally sitting or standing user of the table by the hand switch,considering the following
notes.
b.) This product may only be used by children aged 8 years and older, as well as persons with physical, sensory,
or mental disabilities or lack of experience and knowledge, if they are supervised or instructed by a
responsible person and understand the resulting dangers. Children must not play with the device. Cleaning
and user maintenance may not be performed by children without supervision.
c.) The factory-provided power strip may be charged up to a maximum of 3500 watts as documented with the label
on the power strip mount.
d.) The maximum additional load of the height-adjustable table is 50kg.
e.) The operator must ensure that there are no persons or objects in the hazard area. There must be no objects
higher than 610 mm below the table.
f.) The electrically height- adjustable desk SONO is determined for the use in office space, only in dry environment.
Temperature range is +5°C to +40°C. Maximum duty cycle is ED 10% (S3, = 2 min. operation, 18 min. interruption)
Assembly according to the additional installation instructions!
g.) Precondition for the initiation of the table: Electrical installation, setup and initiation have to be done by qualified
personnel in accordance to the assembly instruction. If parts of the system are visibly or otherwise appreciably
damaged, the furniture must not be installed or put into operation. Please contact our service address
immediately.
h.) It is important to ensure that cables have not been crimped or damaged in any way.
Check regularly all cables in the area of the flank legs if they have been pinched between the lower end of the leg
and the ground.
Standing on soft floor coverings, the adjustable stands may gradually subside into the ground. At such pre-
conditions, please provide additional ground clearance in the beginning.
ATTENTION:
In case of non-observance: risk of property damage and damage to persons by electric shock.
Adjust the height of the adjustable stands as follows: Ø of the biggest cable in mm + 4mm = ground clearance.
On soft floorings significantly more additional reserve is necessary because of the risk of subsidence. Retain the stands
against unintentional readjustment by tightening/ fixing the nut against the base plate.
Cleaning work, moving of the table:
Turn off the power supply for cleaning work at the table. For wet cleaning of floor covers: The power supply of the table
is lead beneath the cladding of the table cheeks, invisible for outsiders. For cleaning workers the following orientation is
essential.
„In the range of the table cheeks and the power connection water and cleaning agent must not be used flooding or in
large amounts. Danger of death due to electric shock!“
ATTENTION:
Never move the table frame sideways!
Cables lead in a floor outlet or cables mounted onto the ground could be pinched or sheared off!
Danger of death due to electric shock!

Electrical and mechanical components:
a.) In case of damage of the electric cable, the device mustn’t be operated any more. The damaged cable must
be replaced by a new, special electric cable delivered by Wilhelm Renz GmbH + Co.KG. Install the new cable in
the reverse order. The strain relief must be reattached.
b.) Owing to any further work or modification on the cabling, the height adjustment or any other parts of the table
by others than the producer or his servicing, the CE declaration of conformity by Renz is lapsed.
c.) The power supply must be interrupted immediately if electrical components, drive or mechanics cause unu
sual noise or odors during operation, or behave unexpectedly or atypically.
d.) In order to interrupt the power supply a freely accessible separator must be intended by customer. For examp
le the deduction of a power plug, the operating of a switch or a fuse ensures that the power supply can be
interrupted completely and as fast as possible.
ATTENTION:
The utilized separator has to provide a contact section opening width according to the terms of overvoltage category
III for complete detachment. It has to be integrated into the static electric system according to the valid regulatory
statues.
e.) The distance of movable table elements to permanent components (for example walls, columns, projections,
windowsills, containers and sideboards (ancillaries) must be at least 500 mm, to prevent violent pressure.
f.) Objects and devices on the table must be protected against falling down, make sure that cables of equipment is
long enough for highest / lowest position of the table . Use cord grips for traction relief.
g.) Keep in mind that movable furniture like swivel chairs (armrest, back support) or construction elements like
casements might slew round into the area of movement of the table. Violent pressure or blocking of the height-
adjustment may result.
Blocking of the height-adjustment may cause overload, toppling over or destruction of components.
h.) Persons or heavy objects must not be placed on the tabletop. Otherwise the height adjustment may be
damaged or the table might tip over.
i.) The moving table might destroy objects (hazard of shivers) or cause violent pressure.
j.) Keep away beverages and other liquids from the electrification in the table top. Danger of death due to electric
shock or danger of malfunction by spilling liquids into the power box or power strip.

2. Lifetime of the lifting columns
In normal use and in accordance with the intended use, in accordance with the respective technical
standard, the service life of the lifting columns is designed for a maximum of 10 years.
If this period is exceeded, we strongly recommend replacement.
Under certain circumstances, the service life on which the standard is based can be affected by improper use
or reduce excessive load. Warranty and guarantee claims remain unaffected by this.
WEEE-Reg.-Nr.: DE 75824099
3. Unintended use :
Unintended use, improper treatment or handling may cause risk or hazard to people or objects.
ATTENTION:
By unintended use the manufacturers liability and the general type approval will lapse. Modifications from the
factory-made delivery status are not permitted and result into extinction of the liability of Wilhem Renz GmbH +
Co.KG.
a.) The desk must not be used in humid or corrosive areas or areas exposed to explosion hazards.
b.) The desk must not be used for hoisting or lowering people or objects. Do not block the mechanism.
c.) Never use the desk for ascension, never stand onto the desk.
d.) By barriers in the movement range that might block the height adjustment, people or objects could be tipped
over, torn down, pinched, bruised or damaged in any other way.
e.) Barriers might even block the height adjustment and overcharge mechanical and electrical components.
Overcharging of electrical components causes fire hazard.
f.) The hand control switch must not be mounted in another position.
g.) The operation of the desk is not allowed in case of:
- non-observance of safety instructions
- the absence of a free accessible separator, provided by customer (see 5/f.)

Function and operation, ergonomics
Ergonomics
a.) Always adapt the table height to your respective working position.
b.) For screen handling make sure that the top line on the screen is below your horizontal view axis.
An advantageous bearing results by a viewing direction 35° beneath the horizontal line. The screen surface
ideally shows an angle of 90° with the viewing axis.
c.) The working height (for sitting and standing work) should be the height of your elbow at loose-hanging upper
arms.
d.) For further detailed information we refer:
- Germany: Guideline for workplace design, published by the mutual indemnity association
(Berufsgenossenschaft)
- Outside of Germany: Country-specific guidelines / regulations.
