AquaTrend Interface Power and Network Connections
1. Make sure no power is being supplied to the power supply.
2. Use a flat-blade screwdriver to loosen the screws of the AquaTrend
Interface face.
3. Lift the face off the AquaTrend Interface. Disconnect the ribbon cable from
the circuit board in the back enclosure and set the face aside. Or, store it
by screwing the right side of the face to the left side of the back enclosure.
4. Use a punch and hammer to remove one knock-out on the inside rim of
the bottom housing. Position the punch in the center of the knockout for
best results.
Note: To assure the AquaTrend Interface continues to meet NEMA 4X, I.P.66
enclosure ratings, use only the supplied NEMA-style enclosure strain relief fittings.
5. Refer to the first two columns in
the six-position terminal block (J2) as shown in
flat-blade screw driver to depress each nylon lever, then insert the
appropriate wire into the terminal block.
Note: If any color wire is not present in the terminal block, skip that connection.
Note: Although conduit is generally not required for low voltage network wiring,
conduit, if used, must be bonded together by the customer. This product does not
provide automatic conduit bonding.
6. Make other wiring connections at this time if necessary, then attach the
AquaTrend Interface face with the four screws removed earlier. Tighten
the screws to 10 in-lb (1.1 n-m) maximum. Do not overtighten the screws.
