LC101 Module Interface Connector

The LC101 Module interface connector is a 4-pin connector (Molex P/N 22-11-2042). The host
may use a 4-pin polarized housing (Molex P/N 22-01-3047 with Molex 2759 series terminals) or
equivalent.

Watertrap Switch Connection

Watertrap switch connection is via a 2-pin Molex connector on the Main Board.

Pump

The pump is mounted on the Main Board. The pump wiring harness is connected to the Main
Board via a 2-pin connector (Molex P/N 22-01-3027).

The pump wiring meets typical insulation standards but does not meet patient isolation
requirements. If the pump must be moved to a different location, patient isolation requirements
must not be compromised. Refer to Section 6, Regulatory, for additional regulatory and safety
information.

Watertrap Receiver

The internal space available in the host monitor must be considered when incorporating the
watertrap receiver into the host system design. To accommodate various OEM dimensions, two
watertrap receivers are offered: long and short. The long watertrap receiver requires more
intrusion into the host monitor but the watertrap does not protrude as far externally from the host
chassis than with the short watertrap receiver.
