• Be sure to connect pin number 5
(GND) of COM1 and COM2 (RS-232C)
to the host unit's Signal Ground
terminal.
• Be sure to confirm what settings will be
used by the other device and set the
slide switches accordingly. Failure to
do so can result in a unit malfunction or
damage.
• Whenever changing the PS-B
switches, be sure to first turn the PS-
B's power supply OFF. Failure to do so
can cause a PS-B malfunction.
• Connect the FG terminal line to the
shell.
• FG and SG terminals are internally
connected in the PS-B. When
connecting to another device, be sure
not to create an SG shorting loop in
your system.
Installations
1. Installation Requirements
• For easier maintenance, operation, and
improved ventilation, be sure to install the
PS-B at least 50mm [1.97in.] away from
adjacent structures and other equipment.
120mm [4.72in.] space (minimum) is
necessary at the front for cable curve.
• Be sure that the surrounding air
temperature and the ambient humidity are
within their designated ranges.
(Surrounding air temperature: 0 to 50
°C,
Ambient humidity: 10 to 90%RH, Wet
bulb temperature: 39
°C or less)
Check the surrounding air temperature 30
mm [1.18 in.] away from the main unit.
Ex.: Horizontal mounting
.
• Be sure that heat from surrounding
equipment does not cause the PS-B to
exceed its standard operating temperature.
2. PS-B Installation
• Determine the thickness of the board in
consideration of its strength. The
