Command THC Control PC Board Calibration
REQUIREMENTS
ELECTRIC SHOCK CAN KILL
• Turn off the power and remove the input power plug from its receptacle before
removing any access cover. If the power supply is directly connected to a line
disconnect box, switch the line disconnect to OFF (O). In the U.S., use a "lock-out
/ tag-out" procedure until the service or maintenance work is complete. In other
countries, follow appropriate national or local safety procedures.
• Do not touch live electrical parts! If power is required for servicing, use extreme
caution when working near live electrical circuits. Dangerous voltages exist inside
the THC control module that can cause serious injury or death.
STATIC ELECTRICITY CAN DAMAGE CIRCUIT BOARDS
• Put on a grounded wrist strap BEFORE handling PC boards.
