CHAPTER 3: SCOPE
SECTION 31: To the Installer
The purpose of this manual is to familiarize the installer and purchaser with the proper installaon and operaon of this system.
It is essenal that this equipment be properly installed and operaonal before the door is used by the public. It is the installer’s
responsibility to inspect the operaon of the entrance system to be sure it complies with any applicable standards. In the United
States, ANSI Standard 156.10 (Full Power) and ANSI Standard 156.19 (Low Energy) covers the GT20 Swing Door Operator Assembly.
Other local standards or codes may apply. Use them in addion to the ANSI standard. Both Full Power and Low Energy Swing door
Units are listed by UL according to UL325 and is idened as such on the label.
Instruct the building owners and operator on the essenals of the operaon of this device. The owner should follow these
instrucons to determine whether the door is operang properly and should immediately call for service if there is any malfuncon.
All installaon changes and adjustments must be made by qualied, NABCO trained technicians.
Replacement labels and literature may be obtained from local NABCO Entrances, Inc. Distributors. If the name of the local distributor
is unknown, contact NABCO Entrances, Inc. at 1-877-622-2694 for assistance.
The owner should determine that the door is operang properly and should immediately call for service if there is any malfuncon.
All installaon changes and adjustments must be made by qualied, NABCO trained technicians.
SECTION 32: Objecve
The Swing Door Operator assembly is designed to be installed onto the top surface of the Door Frame, or Door Panel. This manual
was created to oer step by step instrucons..
A pedestrian Door that does not have Its glass secons installed at the Factory
shall specify that the glazing material employed is to comply with the requirement in
UL 325 par2951:
“The glazing material in both xed and sliding panels of all sliding doors and in all
unframed swinging doors shall comply with the requirements in the Performance

CHAPTER 4: 120 VAC GENERAL WIRING
Shut the installaon site, branch Circuit Breaker OFF Failure to do so may result in serious
personal or fatal injury When uncertain whether power supply is disconnected, always
verify using a voltmeter
All high voltage electrical connecons must be made by licensed electricians according to
Naonal and Local electrical codes/regulaons
Permanent wiring shall be employed as required by local codes
Keep all Incoming 120 VAC wiring separate from low voltage wiring within Header 120 VAC
Power wires must be routed (separate from other wiring) located near the top of inside Header
Ensure that the Grounding of the Electric Power Supply is installed/connected in a proper way
(especially the PE Cable from the Building Side)
All cable used for eld wiring from a Class 2 circuit of an operator to an external device shall be:
a Type CL2, CL2P, CL2R, or CL2X complying with the Standard for Power Limited Circuit Cables,
UL 13, or
b Other cables with equivalent or beer electrical, mechanical, and ammability rangs
Aenon: Depending upon the installaon, the Power Switch/Program Selector may have to be installed
on the opposite side of the Header If 120 VAC Power wires must be installed from Hinge Side of
Header, ensure all wires are securely clipped to prevent pinching of the wires during the Motor/
Operator installaon process
Aenon: Electrical circuit to Nabco operator must not be not shared with other equipment such as lighng,
cash registers, or any device that might cause electrical interference on the circuit
Aenon: Insert all Incoming 120 VAC Power wires into the pre drilled Electric Service Access Hole located at
the le or right side of Header End Cap
Note: It is recommended for the Installer to house all Incoming 120 VAC wires within an Electrical Conduit.
1. Connect the Main Power Supply.
2. Mount the Side Cover.
