Instruction Bulletin NQOD242ASP, NQOD242ASP-N, NQOD142ASP-E, AND NQOD142ASP-NE POWERLINK® AS POWER INTERFACE MODULES (FOR USE IN 100 AMP AND 225 AMP NQOD PANELBOARDS WITH POWERLINK® AS SYSTEM INSTALLED) Interface Module Catalog Number Voltage Rating NQOD242ASP, NQOD242ASP-N 208, 240 Vac NQOD142ASP-E, NQOD142ASP-NE 120 VAC KIT CONTENTS: Interface Module Wire Terminations Installation Information 1 1 pkg 1 TOOL REQUIREMENTS: Screwdriver, Small Straight-Blade Wire Stripper, Voltage Meter 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 A red wire appears only on models NQOD142ASP-E and NQOD142ASP-NE. See figure 5 on page 3. F Figure 1 E A 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. RESET D C B ! 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, Figure 2 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. , and Square D are Registered Trademarks of Square D Company. © 1999 Square D All Rights Reserved 1 Bulletin 63249-201-200 October, 1999 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. F B B D D E A Top View G G Failure to observe these precautions can result in equipment damage and void warranty. Figure 3 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. D D Gently shift control bus rails up/down to align control bus connectors with 25-pin connectors on power interface module. G G Figure 4 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. © 1999 Square D All Rights Reserved Bulletin 63249-201-200 October, 1999 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.

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.
