2.1 ELECTROSTATIC DISCHARGE (ESD)
RECOMMENDATIONS
• Before making wiring connections or
touching circuit boards or other internal
components, discharge any static elec-
tricity from your body by touching a grounded metal
object.
• When making wiring connections, make sure to
remain properly grounded by wearing an ESD wrist
strap or similar device.
2.2 CUSTOMER-SUPPLIED ELECTRICAL
EQUIPMENT
The user must supply the following:
• 18-12 AWG wire for electrical connections using
conduit or 100-240 VAC power supply

tic wire jacket is clamped into the terminal strip, con-
nections will not be made.
• Clip or cap any unused wires.
DANGER
Make sure that power to the instrument is discon-
nected before making any wiring connections.
