SAVE THESE INSTRUCTIONS

WARNING: Maximum equipment loading of table assembly in addition to specied top is as follows:

■ Maximum top weight: 244 lb (110.9 kg)

■ Maximum 2 Stage (ST2E-XXXX-XXXX-XCF-XX-X) Equipment Load: 100 lb (45.4 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 Sentinel Work Center.

DANGER: To reduce the risk of electric shock, always unplug this Sentinel Work Center from the electrical outlet before cleaning or servicing.

WARNING: To reduce the risk of burns, re, electric shock, or injury to persons:

1. Unplug from outlet before putting on or taking off parts.

2. Close supervision is necessary when this furnishing is used by, or near children, invalids, or disabled persons.

3. Use this Sentinel Work Center only for its intended use as described in these instructions, do not use attachments not

recommended by the manufacturer.

4. Never operate this Sentinel Work Center if it has a damaged cord or plug, is not working properly, has been dropped or

damaged, or dropped into water. Return the furnishing to a service center for examination and repair.

5. Keep the cord away from heated surfaces.

6. Do not operate outdoors.

7. Do not operate where aerosol (spray) products are being used or where oxygen is being administered.

8. To disconnect, remove plug from outlet.

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 certied electrician to install the correct matching polarized electrical outlet.

Caution: Never modify the power cord plug in any way

Double-Insulated Products Instructions:

Some products are double-insulated. No means of grounding is required or provided on a double-insulated product; nor is a

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 conguration 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.

Warning: Doing so may cause risk of electrical shock or re

Illustration Disclaimer—Power Plug and Receptacle Images:

In some cases, the images in this instruction may not match the power cord supplied with your electrical furnishing based on your region.

Plug type, blade size, and shape may change.

TROUBLE SHOOTING

Note: If the table does not operate properly upon power-up, a cable connection may not be connected correctly.

Two things must be done to correct this problem.

Step 1.) First check all cable connections to the power supply. If cables are properly connected they will be locked in place. If you pull back

on each cable and one comes unplugged, re-insert the cable and push in rmly until it locks. Test by pulling back to be sure the cable is

properly connected.

Step 2.) Perform the “Restore Factory Settings” procedure. Follow the “Restore Factory Settings” instructions and reset the system.

Note: It’s important to follow the steps precisely as noted or the “Restore Factory Settings” may not restore properly allowing both of the legs of the

table to operate properly once the connection issue is corrected. Repeat the “Restore Factory Settings” procedure again if necessary

Once you’ve corrected the connection problem and performed the reset the table should operate as normal. Repeat starting with Trouble Shooting

Step 1 if the table still does not operate properly.

If you still have problems with your table, please contact Workrite Ergonomics at (800) 959-9674 “Press 2 for Technical Support” or contact us at

[email protected]

With this function, you can reset the Sentinel series switches to their original factory settings.

Caution: Restoring "Factory Settings" will remove height limits. Perform this step only if needed to restore the table
