    4.2.1 PANEL-MOUNT CONFIGURATION Outline dimensions and mounting details for the panel-mount FPU-16 are shown in Figure 3. The FPU-16 mounts in a 92-mm (3.62-in) square cutout (1/4 DIN) and is secured to the panel by the panel-mount clamp. To mount the FPU-16, insert it through the panel cutout and slip the panel-mount clamp over the FPU-16 body.

  • Page 30: Shielded Cables

    Input-cable shields from the ICT-2, the operation-counter switch, and the remote program-enable switch must be grounded at the FPU-16 end only. Analog- and communications-output cables should be grounded at the receiver end only. Terminate foil-shielded input cables as shown in Figure 8: Strip 150 mm (6") of outer jacket from the cable.

    FPU-16 terminals 20 and 21 to allow programming. If the switch is mounted more than 1 m (3 ft) from the FPU-16, use shielded cable and ground the shield at the FPU-16 end only. 4.4.7 ANALOG OUTPUT An isolated analog output is available at terminals 23 and 24.

  • Page 35: Residual Earth-Fault Connection

    For surface-mount units, restrain the conductors by fastening the "P" clips to the mounting surface. For panel-mount units, secure the "P" clips to the FPU-16 rear panel. Secure cables to the ICT-2 using the cable-tie eyelets and the cable ties provided.

  • Page 42: Analog Module

    A 50-pin bus connector on the display module accepts a backlighting, remote input, or RS-485 communications interface module. FIRMWARE The FPU-16 has a two-cycle sampling interval followed by a one-cycle calculation interval. In each sampling interval, the multiplexed A/D converter obtains 200 samples of the earth-fault and phase-current signals.
