Make the connections at the PS1201 end as follows:
51350-18 Hardware Installation.fm
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 PS1201 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 end of each wire if desired.
8. Insert the wires into an available connector in a six-position terminal block
of the PS1201. Refer to
10 for wire position.
9. Tighten the strain relief fitting using the supplied washer and locknut until
the cable no longer slides in the strain relief.
Note: To ensure the PS1201 continues to meet NEMA 4X, I.P.66 enclosure ratings,
use only the supplied NEMA-style enclosure strain relief fittings.
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.
