7. Starting, operation
Cable connection in the spring clip terminal
Cover the stripped wire ends with end splices.
Unscrew the case cover.
Loosen the cable gland using an open-end wrench, wrench size 24.
Lead the cable through the cable gland into the opened case head.
Press the corresponding plastic lever at the spring clip terminal down using a screw driver, so
that the clamped contact will be released.
Lead the prepared flying lead into the opening and let go of the plastic lever, so that the flying
lead will be squeezed inside the spring clip terminal.
After connecting the individual wires, tighten the cable gland and screw down the case over.
Function of the test circuit for 2-wire
By means of the test circuit the current can be metered during normal operation without having to
disconnect the instrument. For that purpose you have to connect an ammeter (internal resistance
< 15 Ohm) to the test +/- terminals
5. Ensure that the conductor outer diameter you select is matched to the angle housing’s
cable gland. Slide the cable through the cable gland nut (2), washer (3), gland seal (4) and
angle housing (5).
6. Connect the flying leads to the screw terminals on the terminal block (6) in accordance
with the pin-assignment drawing.
7. Press the terminal block (6) back into the angle housing (5).
8. Tighten the cable gland (2) around the cable. Make sure that the sealing isn’t damaged
and that the cable gland and seals are assembled correctly in order to ensure ingress
protection.
9. Place the flat, square gasket over the connection pins on the top of the instrument
housing.
10. Slide the terminal block (6) onto the connection pins.
11. Secure the angle housing (5) and terminal block (6) to the instrument with the screw (1).
