It does notprovide instructions for diagnostics, maintenance, service, or troubleshooting. Reference the 4088 MultiVariable Transmitter Reference Manual for more instruction. All documents are availableelectronically at and instructions in this section may require special precautions to ensure the safety of thepersonnel performing the operation. Information that raises potential safety issues is indicated with awarning symbol ( ). Refer to the following safety messages before performing an operationpreceded by this symbol. WARNINGE xplosions could result in death or serious of this Transmitter in an explosive environment must be in accordance with theappropriate local, national, and international standards, codes, and practices.

2 Review theapprovals section of the 4088 MultiVariable Transmitter Reference Manual for any restrictionsassociated with a safe installation. Before connecting a Field Communicator in an explosive atmosphere, ensure the instrumentsin the loop are installed in accordance with intrinsically safe or non-incendive field wiringpractices. In an Explosion-proof/Flameproof installation, do not remove the Transmitter covers whenpower is applied to the leaks may cause harm or result in and tighten process connectors before applying shock can result in death or serious contact with the leads and terminals. High voltage that may be present on leads can causeelectrical entries Unless marked, the conduit/cable entries in the Transmitter housing use a 1/2 14 NPT threadform. Entries marked M20 are M20 x thread form. On devices with multiple conduitentries, all entries will have the same thread form.

3 Only use plugs, adapters, glands, orconduit with a compatible thread form when closing these entries. When installing in a hazardous location, use only appropriately listed or Ex certified plugs,adapters, or glands in cable/conduit required for Quick the 4 Consider housing the and power up ..14 Verify device the 25 Product Start GuideApril 20192 Rosemount 4088A MultiVariable Transmitter Quick Start Guide1 Steps required for Quick installation Start > Mount the Transmitter : Mount the Transmitter Consider housing rotation: Consider Housing Rotation Set the switches: Set the Switches Wiring and power up : Wiring and Power Up Verify device configuration: Verify Device Configuration Trim the Transmitter : Trim the Transmitter > FinishApril 2019 Quick Start GuideQuick Start Guide32 Mount the flow applicationsProcedure1.
