Fig. 7. Grounding and power wiring connections to NPB-PWR-UN-H module.
Power Wiring
There are two power options for the WEB/CP-700 controller: the NPB-PWR-UN-H power supply module (typical), or a NPB-
WPM-US (Wall Mount AC Adapter).
NPB-PWR-UN-H
The NPB-PWR-UN-H module lets you power the WEB/CP-700 (and if installed, connected I/O modules) from AC line power, with
a universal input range from 90–263Vac. The NPB-PWR-UN-H installs on the left side (end) of the WEB/CP-700 controller. See
Fig. 7.
WARNING
A 120Vac or 240Vac circuit powers the NPB-PWR-UN-H. Disconnect power to this circuit before installation to
prevent electrical shock of equipment damage.
Make all connections in accordance with national and local electrical codes. Use copper conductors only.
Do not exceed the 30W capacity of NPB-PWR-UN-H by the powered devices.
Power input connections are made to the terminals on the NPB-PWR-UN-H circuit board (cover removal is required). Use the
supplied earth grounding wires to make a connection from a nearby earth ground to the grounding lug on both the
NPB-PWR-UN-H power supply and the WEB/CP-700 controller. See Fig. 7, page 15.
