Mechanical Installation
November 2017
Recommended tools for installation:
A set of small precision screwdrivers (for the terminal blocks)

13 mm open wrench

4 mm Hex key (preferably with a handle)

Large adjustable wrench

Wire cutter, pointed pliers, insulating tape

Laser measurement device or equivalent

RS-485 to USB converter, including drivers

120 Ω (RS-485) resistor

250 Ω (HART

PC or laptop

DC voltmeter and Ohm meter

Complete the following steps before installing the Rosemount 5708.
Power
Make sure grounding is done properly. Connect one end of the cable shield to the power ground. It is

highly recommended to have the same potential grounding to all the Rosemount 5708.
Prepare a 24 Vdc power supply near the Rosemount 5708 mounting location.

Make sure that you use proper cables for wiring. The Rosemount 5708 is a 4-wire device. The voltage

supply and data output (4-20 mA) are carried along two separate two-wire connection cables.
Communications
For RS-485 communication, use shielded, twisted-pair cables with 120 Ω impedance. Make sure the

cables are approved for RS-485 communications.
Route communication cables in proper conduits. Use a proper cable type.

For 4-20 mA communication, use shielded, twisted-pair, low resistance cables. Make sure the cables

are rated for analog signals.
For daisy chaining, a single 4-wire cable can be used, both for RS-485 and the

24 Vdc power supply.
