Static Discharge Precautions
39
The electronic circuits in the Secure II are completely protected from static electricity damage only while the
bed is assembled. It is extremely important that all service personnel always use adequate static protection
when servicing the electronic systems of the Secure II. Whenever you are touching wires, you should be
using static protection.
Static Protection Equipment
The necessary equipment for proper static protection is:
1 static wrist strap; 3M part number 2214 or equivalent,
1 grounding plug; 3M part number 61038 or equivalent,
1 test lead with a banana plug on one end and an alligator clip on the other; Smith part number
N132B699 or equivalent.
CAUTION
All electronic service parts will be shipped in static shielding bags. Do not open the bags until you have com-
pleted steps 2 and 3 of the following procedure. Do not place unprotected circuit boards on the floor. All circuit
boards to be returned to Stryker Medical should be shipped in the static shielding bags the new boards were
shipped in.
Static Protection Procedure
1. Unplug the power cord from the wall receptacle.
2. Insert the grounding plug into a properly grounded hospital grade wall receptacle. Plug the banana plug
of the test lead into the receptacle on the grounding plug. Connect the alligator clip on the other end of
the test lead to a ground point on the bed.
3. Place the static control wrist strap on your wrist. Connect the alligator clip at the other end of the wrist strap
cord to a ground point on the bed.
