SAVE THESE INSTRUCTIONS
WARNING: Maximum equipment loading of table assembly in addition to specied top is as follows:
Maximum Top Weight: 83 lb (37.7 kg)
Maximum Equipment Load: 225 lb (102.2 kg)
Loading should be evenly distributed over table surfaces.
V = 120 VAC, 60 Hz / 4 A maximum
FLAMMABILITY: All worksurfaces used must meet UL 962 ammability requirements
Flame Spread Rating maximum 200
Smoke Developed Index maximum 450
WORKSURFACE MATERIAL: This frameset is designed to accommodate worksurfaces made from Industrial Particle Board with nominal thickness
of 1.125". If the worksurface is not appropriate or not mounted correctly to the table, it could cause the complete table to be unstable, it may collapse,
and for an adjustable table, the electrical components may fail.
Intended for indoor use only.
For commercial use only.
IMPORTANT SAFETY INSTRUCTIONS:
When using an electrical furnishing, basic precautions should always be followed, including the following:
Read all instructions before using this Sierra HX Work Center.
DANGER: To reduce the risk of electric shock, always unplug this Sierra HX Work Center from the electrical outlet before cleaning or servicing.

9. Do not exceed maximum load recommendations.
Polarized Plug Instructions (Only applicable to products having a polarized plug power cord):
Some products include a polarized plug—see Figure A (One A/C plug blade wider than the other)—to reduce the risk of
electrical shock. A polarized plug only ts a polarized power outlet one way. If the polarized plug does not t properly into the
electrical outlet turn the power plug over to see if it then ts properly and fully into the outlet. If the plug does still does not t
the outlet, contact a certied electrician to install the correct matching polarized electrical outlet.

means for grounding to be added to the product. The plug in a double insulated system is shown in Figure A. Double-insulated
products are indicated with markings of “double-insulated” or the “double box symbol” or both.
Grounding Instructions (For grounded electric products only):
Products with grounded power cords are for use on a nominal 120 V circuit and has a grounded plug as shown in Figure B
Make sure the product is connected to an electrical outlet having the same conguration as the plug shown in Figure C.
Caution: Never modify, remove, or use adaptors that eliminate the ground connections from the grounded power cord
A/C Power:
Products sold in North America and other regions are 120 V A/C as marked on the power supply/control box of the furnishing
and are to be used on a normal 120 V A/C circuit. Always follow the instructions above for power connection using grounded or
double insulated power cords as supplied.
• Only use power cord(s) supplied with your electric product
• Never modify, alter, use an adaptor, or change the electrical system of this product in any way.
