RUI Section
RUI Overview The 4007ES RUI channel supports the
following devices:
• 4100-7401, 7402 Graphic Modules
• 4602-6001, -7001, 7101, 9150 RCU/SCU
Modules
Wire from the power supply's RUI channel on
terminal block TB1 to each RUI device. The
wiring may be Class A or Class B.

Figure 5-8 depicts Class A and Class B wiring.
Figure 5-8. RUI Wiring to the Host Panel
Supports: up to 10 RUI devices.
Electrical Specifications:
Channel Voltage 29.5 V nominal.
Earth Detection Threshold
10K ohms minimum from either positive or
negative terminals.
Capacitance
The maximum allowed line-to-line capacitance
(“+” to “-” terminals) is 0.58uF. For applications
with shielded wire, be sure that the total
capacitance from line-to-line plus the shield to
either line is not more than 0.58uF.
Wiring
Maximum wiring distance:
(18 AWG, 16 AWG, 14 AWG, 12 AWG)
2,500 feet (762 m) to device from PSU card.
Maximum “T” tapping length
10,000 feet (3,048 m).
Notes:
Maintain correct polarity on terminal connections. Do not loop wires under terminals.
If Class A is not used, configure jumpers P1 accordingly.
Shield wire is not required. Twisted wire is recommended for improved noise immunity.
