The POWERLINK AS Power Interface Module provides voltage sources for circuit breakers and system electronics, monitors the status of
POWERLINK AS circuit breakers, and reports the
status to the control module. Also, the power
interface module has input terminations for connection to external control devices.
The power interface module (A) is installed on a
100 amp or 225 amp NQOD panelboard interior (B)
to connect POWERLINK AS control bus (C) and its
QO-AS or QOB-AS remotely operated circuit breakers (D) with a POWERLINK AS control module
(E). The interface module provides power to the
POWERLINK AS system and provides connection
for field-installed control wire.

A red wire appears
only on models
NQOD142ASP-E and

If external control wiring is used, a Class 2 barrier
kit (F), Cat. No. ASBK-S (straight end) or ASBK-B
(90° angle end), is required. If necessary, two barrier kits (one straight end and one angle end) may
be used. The interface module accepts up to 16
two-wire maintained or 8 three-wire momentary
external switch inputs. An optional expansion
cabinet can be added to support additional inputs.
Power interface modules also accept POWERLOGIC® network communications wiring.

WARNING
HAZARD OF ELECTRICAL SHOCK OR BURN
Turn off all power to panelboard before installing
interface module or other components. Any work
done on panelboard system must be performed
by a qualified electrician.
Failure to observe these precautions can
result in death or serious injury.
POWERLINK, POWERLOGIC,

NOTE: The power interface module cannot be
installed in an NQOD panelboard which does not
have POWERLINK AS control bus installed. Do
not use power interface module in 400 or 600
amp, column-width, or 14-inch wide panelboards.

CAUTION
C
HAZARD OF EQUIPMENT DAMAGE
Control module can be damaged by panelboard
latch. Install interface module so that control
module, when installed in front of interface
module, will not lie under panelboard door latch.
If power interface module (A) is not aligned
correctly on control bus rails (G), module’s 25pin connectors (B) may be damaged if force is
used to attach module. Make sure control bus
connectors (D) are properly aligned with 25-pin
connectors before pushing power interface
module onto control bus rails (figure 4). If properly aligned, power interface module will snap
easily into place. If it does not snap easily into
place, gently shift control bus rails up/down
before trying to attach power interface module.

INSTALL POWER INTERFACE MODULE
Alignment fixture can be
removed for additional
breaker mounting space.
1. Turn off all power to panelboard.
2. Remove panelboard cover and deadfront.
Verify that power is off with a properly rated
voltage meter before proceeding.
Control bus rails
improperly aligned
3. Choose location for power interface module.
The power interface module can be installed at
either end of the control bus (typically at the
top). The control module is positioned in front
of the interface module and should be easily
readable; therefore, the ideal module position
is at eye level or as close to that as possible.
When positioning power interface module close
to where branch wiring enters the panelboard
side, make sure wire bending space meets NEC
Article 373 requirements for wire bending space
for branch wiring.

rails up/down to align

CONNECT NEUTRAL WIRE
Connect power interface module neutral (white)
wire (A) to panelboard neutral assembly (see
figure 5 on following page).
4. Remove connector covers from control bus connectors (D) where power interface module will
be installed (figure 3).
For NQOD142ASP-E and NQOD142ASP-NE only:
5. With connection cap (C) to the left side of
panelboard, position power interface module
(A) with mounting feet (F) directly over mounting rails (E) and with 25-pin connectors (B)
aligned with control bus connectors (D).
The power interface module requires 10 VA.
6. Push power interface module onto mounting
rails until mounting feet snap onto rails.
2
Connect power interface module red wire (D) to
120 Vac external power source (see figure 5).
NOTE: If the power interface module has a red
wire, it must be connected to a 120 Vac source for
the equipment to function properly.

INSTALL EXTERNAL CONTROL WIRING
B
If using no external control wiring, skip to COMPLETE INSTALLATION section. External control wiring is Class 2, requiring use of one or two barrier kits
(Cat. No. ASBK-S or ASBK-B), ordered separately.
C
The power interface module will accept up to 16
two-wire maintained or 8 three-wire momentary
external switch inputs. (Figure 9 on back page
shows control terminals.) Switch inputs must be novolt dry contact closures suitable for 5 V dc, 1 mA
contact signals. Use #18–22 AWG Cu stranded wire.

COMMUNICATIONS WIRING
If multiple panelboards are to operate on a network, network control wiring between power interface module RS485 (COMMS) terminals must
be connected as shown in figure 8. Control wiring

through the panelboard deadfront, remove the
six twist-outs in deadfront corresponding with
power interface module position.
2. Proceed with installation of POWERLINK AS
remotely operated circuit breakers as instructed
in their instruction sheets. If not installing
circuit breakers at this time, replace panelboard
deadfront and cover.

Table 1 (right) illustrates the factory default input
mapping for power interface modules. This table assumes a panelboard of 42 pole spaces.
If panelboards have less than 42 pole spaces, the input mapping illustrated still applies. For example, for
a 24-circuit panelboard, inputs 1 and 2 would control breakers 1–12 and 13–24, respectively, and input
3 would not be used.
* Inputs 4 and 8 may be used by master switches to operate all breakers on/off.
Table 1
NOTE: Factory default input mapping is erased when a
POWERLINK AS Control Module is installed on the
power interface module. (For more information, see the
control module instruction bulletin.)
