Table 5 802L Rear panel Functions
The function of each item in Table 5 is described in the following sections.
5.15.1. HV Output Connector (Ref 1)
Connector socket for mating HV cable supplied with unit. The connector should be
kept clean and free from debris at all times. If supply is operated at 20kV or 200Hz rep
rate or above the cable should be greased to ensure corona free operation. The cable
connector should only be hand tightened, never use a wrench or apply excessive
force.
5.15.2. Cooling Fan (Ref 2)
Allow at least 4 inches of clearance and do not obstruct clear air flow around the fan.
Cooling air exits through the rear of the unit, and enters through the side panels and
around the HV tank.
5.15.3. Slave Connector (Ref 3)
A 25 pin D-sub female connector that allows connection to a slave supply for
increased power operation.
5.15.4. Remote Connector (Ref 4)
A 25 pin D-sub male connector that allows remote operation and monitoring of all
power supply functions when the unit is operated in REMOTE mode.
5.15.5. Safety Ground (Ref 5)
10-32UNC threaded safety ground stud installed in HV tank. Should be used for
additional safety ground cable between supply and load circuit.
5.15.6. Safety Ground (Ref 6)
M5 threaded safety ground stud installed in HV tank. Should be used for additional
safety ground cable between supply and load circuit.
5.15.7. INHIBIT BNC (Ref 7)
The inhibit BNC input is a standard BNC socket that allows an external connection to
a pulse generator or control system and gives the user control of the power supply
output current. A logic 1 (5-15V) input will inhibit the supply (shuts off the output
current) and a logic 0 (ground or open) allows the supply to operate.
5.15.8. Interlock Terminal strip (Ref 8)
Provides an external dry contact connection for the customer to allow interlock
functions to be controlled. The interlock terminals should be connected to any safety
interlock circuitry in the power supply installation. When the interlock is open the AC
line contactor disconnects the AC line from the power circuitry. The power supply is
shipped with a factory installed shorting link across the interlock terminals.
NOTE
The Interlock terminals are chassis referenced 24VAC
circuits and must never be connected to ground.
