14. Supervisory Link Connector to Termination Board No. 2, 4 Pins (J12): See item 12
on page 3-4.
15. Supervisory Link Supply Indicator, Green (DS12): This LED indicator is lit when the
supervisory link power supply is On.
16. Supervisory Link Connector to Termination Board No. 3, 4 Pins (J13): See item 12
on page 3-4.
17. Supervisory Link Connector to Termination Board No. 4, 4 Pins (J14): See item 12
on page 3-4.
18. ac Supply Fuses (F11): There is one fuse holder for standard 5 x 20 mm fuses (the
rating can be found in Section 13.5 on page 13-7).
19. ac Supply Connector, 3 Pins (J2): The ac line is factory-wired from the ac terminal
block to this connector.
20. Heater Connector, 6 Pins (J3): The enclosure heater is factory-wired to the connector
J3. It consists of two 50-W resistors located under the support bracket of the
electronic circuit board.
21. Voltage Selector Switch (SW1): For wiring details, see Table D-9 on page D-7. This
selector is used to choose between the following:
• 115 V, corresponding to a 90–132 Vac range from 47 to 63 Hz
• 230 V, corresponding to a 180–264 Vac range from 47 to 63 Hz
22. Configuration Communication Status Indicator, Yellow (DS7): This LED, only used
for programmation purposes at the factory, indicates there is a configuration of the
unit through one of the serial ports. It flickers as data bits pass through the H201Ci-C,
whatever the direction and the port (RS-232, RS-485 LAN, USB or optional modem).
23. Communication Status Indicator, Yellow (DS6): This LED indicates that serial
communication activity is present. It flickers as data bits pass through the H201Ci-C,
whatever the direction and the port (RS-232, RS-485 LAN, USB or supervisory link).
