  • Page 3: Introduction

    This addendum to the RM4-RS manual contains information for the installation and operation using the arithmetic mode ARtH or the wind monitor mode NMEA. Refer to the main RM4-RS and RM4-RSA manual for any details not covered in this addendum.

  • Page 4: Mechanical Installation

    Mechanical installation The instrument is designed for DIN rail mounting. The instrument clips on to 35mm DIN standard rails (EN50022). Cut the DIN rail to length and install where required. To install the instrument simply clip onto the rail as shown below. To remove the instrument lever the lower arm downwards using a broad bladed screwdriver to pull the clip away from the DIN rail.

  • Page 5: Electrical Installation

    Electrical installation The RM4 Meter is designed for continuous operation and no power switch is fitted to the unit. It is recommended that an external switch and fuse be provided to allow the unit to be removed for servicing. The terminal blocks allow for wires of up to 2.5mm to be fitted for power supply and relays 1 and 2 or 1.5mm for input connections and optional outputs.
  • Page 6 Power supply connections AC supply connections use terminal G (Active), terminal F (Neutral) and terminal E (Case earth). DC supply connections (12 to 48VDC) use terminal G (DC-), terminal F (DC+) and terminal E (Case earth). Serial input connections Terminating resistors: If long cable runs are used in RS485 or RS422 installations reflections of data signals along the line can in some situations cause corruption of the signal.
  • Page 7 Remote input connections The selected remote input function can be operated via an external contact closure via a switch, relay or open collector transistor switch. Choose momentary or latching switch to suit function selected. Remote input Optional outputs Refer to the separate “RM4 Din Rail Meter Optional Output Addendum” for connection details of optional outputs fitted.
