AquaTrend Interface Power and Network Connections
Please refer to the SOM Manual (Cat. No. 51250-18) for detailed connection
(wiring) information for recorder outputs and relays.
Order enough cable (Cat. No. 52158) from Hach to suit the specific
installation parameters. Connections are made at both ends of the cable; at
the AquaTrend (using the connection information in the first two columns of
Table 11), and to the PS1201 Power Supply (using the information presented
in the third and fourth column of
A Cable Termination Kit (Cat. No. 52156-00) is also supplied for the
connections at the PS1201 end.
1. Turn off all power to the PS1201 Power Supply and disconnect all cables
if necessary.
2. Unscrew the four screws securing the PS1201 face using a
flat-bladed screwdriver.
3. Lift the face off the PS1201 and set it aside. Or, store the front cover
by screwing the right side of the front cover to the left side of the
back enclosure.
4. If necessary, carefully use a punch and hammer from the outside of the
enclosure to remove one of the left three unused knock-outs on the
bottom of the Power Supply enclosure. Position the punch in the center of
the knockout for best results.
5. Install the cable with the strain relief fitting provided in the hole described
in Step 4, above. Make sure the outer cable insulation is just captured by
the strain relief fitting.
6. Strip six inches (15 cm) of outer insulation from the cable
(Cat. No. 52158).
7. Strip ¼ inch of insulation from each wire and insulate the shield wire with
tubing (Cat. No. 40825-00). Tin the ends of the wires if desired.
8. Connect the cable wires to a terminal block of the PS1201 according to
the position information given in the third and fourth column of
page 65. Tighten the screws and tug gently on the wires to check the
connections.
9. Tighten the strain relief fitting using the supplied washer and locknut until
the cable no longer slides in the strain relief.
10. If other power or network connections are to be made at this time, refer to
the appropriate section in this manual or the individual device manual. If
no other connections need to be made, continue with the remainder of
this procedure.
11. Ensure that the gasket is properly seated in the PS1201 face and tighten
the screws to 10 in-lb (1.1 n-m) maximum. Do not overtighten the screws.
