a

 compatible with the WEB/CP 300E and WEB/CP 600E/U Series controller

a

 A wall mount AC adapter (NPB-WPM-US/U) is also available; however, it is not an accessory module that mounts on 

the 20-pin connector of the controller.

WIRING

See Fig. 3 on page 5 to locate connectors and 

components on the controller.

Make connections to the controller in the following order.

1.

Install any option card (LON, RS-485, RS-232, etc.) 

in the available option slots.

See “Installing an Option Card” on page 6 for a pro-

cedure. For complete details, refer to the document 

that shipped with the option card.

If installing the optional NiMH battery, do that after 

inserting option card(s). See “NiMH Battery Installa-

tion and Maintenance” on page 14.

2.

Connect supplied grounding wire from the earth 

ground lug on the controller, as well ground wire for 

each accessory module, to a nearby earth ground-

ing point.

See “Grounding” on page 7.

3.

Prepare power wiring (leave unit powered off). See 

“Power Wiring” on page 7.

4.

Connect communications cables. See “Communi-

cations Wiring” on page 9 for ports on the controller. 

For ports on any installed option card (485-PWR, 

LON, RS-485, modem) see the option’s specific 

mounting and wiring guide for details.

5.

If I/O accessory modules are installed, connect I/O 

wiring. Refer to the appropriate mounting and wiring 

guide for details.

6.

Apply power to the unit. See “Initial power up and 

checkout.” on page 12.

Grounding

An earth ground spade lug (0.187") is provided on the 

controller base for connection to earth ground. For 

maximum protection from electrostatic discharge or other 

forms of EMI, connect the supplied earth grounding wire 

to this lug and a nearby earth ground. Keep this wire as 

short as possible, see Fig. 4 on page 8.

Wire the earth ground spade lug of accessory modules in 

the same manner.

Power Wiring

The controller must be powered by an approved 15 Vdc 

power source. This can be either

a

 DIN-mountable module: 

the NPB-PWR-H/U, a 24Vac/dc-powered module, or the 

NPB-PWR-UN-H/U, a line-powered 120–240Vac module. 

Or, an external Class 2 wall mount AC adapter (NPB-

WPM-US/U) can be used for controller power.

NOTE: See “Environmental Requirements” on 

page 3 for mains supply requirements.

The controller does not include an on/off switch. To apply 

power, you either:

• if NPB-PWR-H/U, plug in its 2-position power 

connector.

• if NPB-PWR-UN-H/U, energize the AC circuit (120–

240 Vac) wired to that module.

• if NPB-WPM-US/U, plug in the power connector to the 

controller.

CAUTION

Do not connect both the NPB-WPM-US/U and 

NPB-PWR-H/U / NPB-PWR-UN-H/U supplies at 

the same time, or equipment damage may 

result.

Power consumption depends mainly on installed I/O 

modules, and may vary from:

• Controller alone (with or without installed option cards): 

approximately 7.5 VA (AC) or 7.5 W (DC).

• Controller (with or without installed option cards), plus four 

(4) IO-16-H/U modules: up to 20 VA (AC) or 20 W (DC).

Option

Description

Notes

NPB-PWR-H/U

DIN-mountable, 24V isolated power module, used to 

power the controller from a dedicated, external, 

Class-2, 24Vac transformer or a 24Vdc power supply.

Only one NPB-PWR-H/U per controller.

• Do not install if using NPB-WPM-US/U or 

  NPB-PWR-UN-H/U.

• For wiring, see “NPB-PWR-H/U” on page 8.

NPB-PWR-UN-H/U

DIN-mountable, Universal 120–240Vac input, 15Vdc 

output, 30W power supply to power the controller.

Only one NPB-PWR-UN-H/U per controller.

• Do not install if using NPB-WPM-US/U or 

  NPB-PWR-H/U.

• For wiring, see “NPB-PWR-UN-H/U” on page 8.

IO-16-H/U

DIN-mountable, 16 points I/O module, used to 

provide I/O points as noted.

Up to four (maximum) IO-16-H/U modules are supported. 

Each provides these I/O points:

• 8 - Universal Inputs (UIs).

• 4 - Digital Outputs (DOs), SPST-relay type.

• 4 - Analog Outputs (AOs), 0–10Vdc type.

Wiring is covered in the IO-16-H/U Installation Instructions.

IO-34-H/U

DIN-mountable, combined 34 points I/O with 24V 

isolated power module, used to provide

 I/O points as well as power the controller from a 

dedicated, external, Class-2, 24Vac transformer or a 

24Vdc power supply.

Only one IO-34-H/U module per controller.

This module provides these I/O points:

• 16 - Universal Inputs (UIs).

• 10 - Digital Outputs (DOs), SPST-relay type.

• 8 - Analog Outputs (AOs), 0–10Vdc type.

Wiring is covered in the IO-34-H/U Installation Instructions.

a

A fourth power option is available: a IO-34-H/U acces-

sory module, which is a combination of the NPB-PWR-

H/U module and two IO-16-H/U modules (plus two extra 

relays). Refer to its mounting and wiring document for 

more details. For a listing of modules, see “About Acces-

sory Modules” on page 6.
