in effect16 C.F.R. § 1211.2 Definition.
As used in this part 1211: Residential garage door operator means a vehicular door operator which:
(a) Serves a residential building of one to four single family units;
(b) Is rated 600 volts or less; and
(c) Is intended to be employed in ordinary locations in accordance with NFPA 70 (incorporated by reference, see § 1211.32).
16 C.F.R. § 1211.3 Units of measurement.
If a value for measurement is followed by a value in other units, in parentheses, the second value may be only approximate. The first stated value is the requirement.
16 C.F.R. § 1211.4 General requirements for protection against risk of injury.
(a) If an automatically reset protective device is employed, automatic restarting of a motor shall not result in a risk of injury to persons.
(b) A residential garage door operator is considered to comply with the requirement in paragraph (a) of this section if some means is provided to prevent the motor from restarting when the protector closes.
(c) An electronic or solid-state circuit that performs a back-up, limiting, or other function intended to reduce the risk of fire, electric shock, or injury to persons, including entrapment protection circuits, shall comply with the requirements in UL 991 (incorporated by reference, see § 1211.40), including environmental and stress tests appropriate to the intended usage of the end-product. Exception: A control or electronic circuit that complies with Supplement SA of UL 325-2017 (incorporated by reference, see § 1211.40) is considered to fulfill this requirement.
16 C.F.R. § 1211.5 General testing parameters.
(a) The following test parameters are to be used in the investigation of the circuit covered by § 1211.4(c) for compliance with either, UL 991, or Supplement SA of UL 325-2017 (incorporated by reference, see § 1211.40):
(1) With regard to electrical supervision of critical components, an operator being inoperative with respect to closing movement of the door meets the criteria for trouble indication.
(2) A field strength of 3 volts per meter is to be used for the Radiated EMI Test.
(3) The Composite Operational and Cycling Test is to be used for 14 days at temperature extremes of minus 35 °Celsius (minus 31 °F) and 70 °C (158 °F).

5. Do not connect opener to source of power until instructed to do so.
6. Locate control button: (a) Within sight of door, (b) at a minimum height of 5 feet above floors, landings, steps, or any other adjacent walking surface so small children cannot reach it, and (c) away from all moving parts of the door.
7. Install Entrapment Warning Label next to the control button in a prominent location. Install the Emergency Release Marking. Attach the marking on or next to the emergency release.
8. After installing opener, the door must reverse when it contacts a 1
1/2 inch high object (or a 2 by 4 board laid flat) on the floor.
9. For products having a manual release, instruct the end user on the operation of the manual release.
