12 INSTALLATION INSTRUCTIONS - ELECTRICAL WIRING

WARNING

TO PREVENT THE RISK OF PERSONAL INJURY OR DEATH :

•DISCONNECT POWER AT THE FUSE BOX BEFORE PROCEEDING.

•ELECTRICAL CONNECTIONS MUST BE MADE BY A QUALIFIED INDIVIDUAL.

•OBSERVE LOCAL ELECTRICAL CODES WHEN WIRING THE OPERATOR.

WARNING: The AUJ-S and AUH-S Series operators have been designed and constructed for use with voltages from 115 Volts AC to 480 Volts AC, in single or three phase. Check the operator nameplate label on the control box cover for the proper voltage and phase. The application of an improper input voltage or phase will result in catastrophic failure to the internal electrical components.

Observe local electrical codes when wiring the operator.

When hard wiring, observe state and local electrical codes. A wiring diagram is attached to the inside of the control box cover. Connect the appropriate voltage and phase power leads to the appropriate terminals as per the wiring diagram and connect a ground wire to the grounding screw. On three phase units, incorrect phasing of the power supply will cause the motor to rotate in the wrong direction (open when CLOSE button is pushed and vice versa). To correct this, interchange any two of the incoming three phase conductors.

The wiring diagram attached inside the cover of the control box details all of the field wiring terminal connections for the operator. Always connect the wires to the push-button controls and auxiliary devices exactly as shown.

Warning: Control voltage of the opener is 5 volts DC, Class 2. Do not run the power leads and control circuit wiring in the same electrical conduit.

WARNING

TO PREVENT THE RISK OF PERSONAL INJURY AND/OR DAMAGE TO DOOR OR PROPERTY, ONLY OPERATE DOOR CONTROL WHEN DOOR IS IN CLEAR VIEW. IF CONTROL STATION CANNOT BE LOCATED WHERE THE DOOR IS VISIBLE OR IF ANY OTHER DEVICE IS USED TO CONTROL THE DOOR AN AUXILIARY ENTRAPMENT DEVICE (DOOR EDGE OR PHOTOELECTRIC) MUST BE CONNECTED.

WARNING

RISK OF ENTRAPMENT THAT MAY

RESULT IN SERIOUS PERSONAL INJURY OR

DEATH. DISCONNECT POWER TO THE

OPENER BEFORE AND DURING

INSTALLATION OF AN ACCESSORY

REVERSING DOOR EDGE OR

PHOTOELECTRIC DEVICE. DO NOT

RECONNECT POWER TO OPENER UNTIL

INSTRUCTED TO DO SO. ENSURE DOORWAY

IS CLEAR BEFORE STARTING TESTING OF

Note: AUJ-S and AUH-S Series model operators are pre-wired for entrapment protection devices. To operate in Momentary Contact To Close mode and comply with the UL325 Entrapment Protection requirements effective Aug. 29, 2010, an approved external entrapment device as described on Page 3 must be installed and connected to the operator. Refer to Figure 8 and the manufacturer‟s instructions to install and connect one of the approved door edge devices. One or more contact sensors shall be located at the bottom edge of a vertically moving door. Refer to the instructions on Page 13 & 14 for the Linear photoelectric system installation and wiring.

If the external entrapment protection device is connected, the selector switches are set properly (Page 17) and the device detects an obstruction or becomes inactive, an opening door continues to open and a closing door stops, pauses and starts open. While in this mode, if a problem is detected while the operator is stopped, a close will require constant activation of the control Close button. If an entrapment protection device as described above is attached and is properly working for 1 second, it will be auto detected and the monitored function will be turned on. Once the monitoring function is active, it will remain active even if the power is removed and the entrapment protection device is disconnected and power is restored. While in this mode, if a problem is detected while the operator is stopped, a close will require constant activation .

Operators which have an operational entrapment protection device as described above may have one or more additional means of control which should be wired in accordance with the diagram supplied in the opener and also illustrated on Pages 23 & 24. To add a second three button station, refer to Figure 11.

Number 22 gauge wire or heavier must be used for wiring the control stations and auxiliary control devices to the operator. Smaller gauge wire will cause operational problems, especially when multiple push-button stations are used or during summer months.
