6 LO and GUARD
Banana safety jacks for output low and banana jack Guard.
7 TRIGGER LINK
Eight-pin micro-DIN connector for sending and receiving trigger pulses among connected
instruments. Use a trigger link cable (Model 8501) for connections.
8 INTERLOCK
Interlock connector – Provides two screw terminals for connection to an interlock switch.
When the interlock switch is closed, the OUTPUT of the 622x is enabled, allowing it to be
turned on. When the interlock switch is opened, the OUTPUT is disabled (OUTPUT can-
not be turned on and will turn off if it was on).
9 Power module
Contains the AC line receptacle and power line fuse. The instrument can operate on line
voltages of 100V to 240VAC at line frequencies of 50 or 60Hz.
Heat sink and cooling vents
The Model 622x uses a heat sink and three cooling vents to dissipate heat. The
right side of the case is cut out to expose the black, finned heat sink. Cooling
vents are provided on both sides of the case and on the top cover.
The heat sink could get hot enough to cause burns. Even if the instrument is
turned off, you should assume that the heat sink is still hot as it takes considerable
time for it to cool off.
WARNING
When handling the Model 622x, NEVER touch the heat sink
located on the right side of the case. This heat sink could be
hot enough to cause burns.
CAUTION
NEVER place a container of liquid (e.g., water, coffee, etc.) on
the top cover. If it spills, the liquid will enter the case through
the vents and cause severe damage.
Excessive heat could damage the Model 622x and at the very least, degrade its
performance. The Model 622x must be operating in an environment where the
ambient temperature does not exceed 50°C.
