WARNING Make sure that electrical connections adhere to local and state legislation and regulations.
WARNING Make sure that you prepare and connect only de-energized wires.
  1. Switch off all communications to the process.
  2. Loosen the bolts on the refractometer cover using a TX20 Torx key. Be careful not to drop the bolts.
  3. Remove the dust plug from the refractometer.
    If needed, you can use the lead-through on the right instead of the lead-through in the middle.
  4. Install the cable gland. Tighten the upper part of the cable gland to 5 Nm using a 22‑mm wrench.
  5. Feed the cable through the cable gland. Ground the cable gland by removing the 15‑mm sleeve from the cable, brushing the metal braid upwards and folding it over. Make sure the wires reach the terminal. Tighten the cable gland to 5 Nm using a 22‑mm wrench. Make sure the wires are not twisting.
    It is not possible to use a conduit hub with PR53SD. If you need to use a conduit pipe, bring the cables close to the refractometer with the conduit pipe and connect through the cable gland. Use the SHIELD connection at the terminal block to ground the connection. For the power side grounding, follow local regulations.
  6. Connect the wires inside the refractometer.
    1. Digital connection
    2. Analog, mA connection
  7. Reinstall the refractometer cover. Tighten screws to 2 Nm using a TX20 Torx key. Be careful not to overtighten. The screws may break.
