Identifying Effected RHF Consoles
To determine if your system is equipped with a RHF console containing a three-capacitor
spark gap assembly:
Turn off power to the power supply and wait 5 minutes before
opening the RHF console.
Open the RHF console and examine the capacitors secured to
the spark gap assembly.
Turn off the power, unplug the power cord and wait 5 minutes before opening RHF con-
sole. If the power supply is directly connected to a line disconnect switch, place switch
in the OFF position. In the U.S., use a "lock-out / tag-out" procedure until the service or
maintenance work is complete. In other countries, follow appropriate local or national
safety procedures.
