BEARING AS-ROLLER 1087930 - Caterpillar

Environmental
* The ambient operating temperature range is from -40° to +70°C (-40° to +158°F)* The storage temperature is from -40° to +85°C (-40° to +185°F).* The unit must be protected from direct contact with liquids (splash-proof). If sealing of the unit is required, the CCM must be in a water tight enclosure.Mounting
The CCM should be located on a desk or shelf. The rubber feet on the bottom of the CCM can also be removed to allow panel mounting. Do not mount the CCM on the engine or within the instrument box. It is not designed for this environment.CCM Battery (Internal)
The CCM contains a battery that supplies power for internal memory whenever the CCM power is turned off. For additional information, refer to the "Replacing the CCM Battery" section.
CCM Mounting Dimensions Wiring Connections and Battery Power
* The Battery voltage input requirements are from 15 to 45 volts DC (24 or 32 volt DC nominal power).* (+/-) B power dissipation is approximately 3.0 watts at 24 volts.
CCM Wiring Connections for Single Unit
(1) CCM.
NOTE A: Shield should not be connected to CCM.General Wire and Cable Specifications
The following specifications for wire and cable is given to reduce voltage drops over long runs of wire and to reduce EMI/RFI interference.* The wires connected to (+) B and (-) B on the CCM must be at least 16 AWG.* Maximum CAT Data Link cable and (+/-) B wire length is 455 m (1500 ft), including wire runs between any multiple Generator Sets.* Maximum total wire length for the RS-232C cable is 15 m (50 ft). In order to conform to the European Economic Community (EEC) 336 Directive, the RS-232 cable must be shielded.* No terminations or splices allowed on the above wires, except as noted in the connection diagrams.* The cable connected to (+/-) CAT Data Link must be 16 AWG, shielded twisted pair cable. Use 123-2376 Electric Cable, Belden 8719 Cable, or equivalent. For additional wiring information, refer to SEHS9951, Customer Communication Module and Programmable Relay Control Model Installed on 3500B Engines with Electronic Instrument Panel. RS-232C Cable Requirements
The CCM is classed as Data Terminal Equipment (DTE) for RS-232C communication.* The CCM RS-232C connector is a standard 25-pin D-shell connector with pins.* The RS-232C cable must be shielded.* When connected to other DTE devices, such as personal computers, a Null Modem cable or adapter is required to connect the two devices.* When the CCM is connected to Data Communication Equipment (DCE), such as modems, printers, or terminals, no Null Modem cable or adapter should be used. If the CCM is connected directly to a PC with a 25-pin RS-232C connector, then a 25-to-25 pin cable is needed in addition to the Null Modem adapter (refer to the following illustration with 25-pin connectors).If the PC has a 9-pin RS-232C connector it requires a 9-to-25 pin cable with a Null Modem adapter (refer to the following illustration with 9-pin connectors).The Null Modem adapter correctly connects the Data Transmit of one device to Data Receive of
