UL Standard for Safety Controllers for Use in Power Production
|Publication Date:||31 May 2019|
These requirements apply to control panels, control units, and other various electrical circuits employed within a control circuit device intended for support functions, maintain operation and limiting safety control features for use in a Stationary Engine Driven Assembly or similar power production equipment control applications.
These requirements cover controls operating at 600 Volts a. c. or d. c maximum with sensing and measurement circuits without the use of isolation devices and 36 kV a.c. or d.c. maximum with the use of isolation devices.
These requirements apply only to electrically operated control equipment.
These requirements apply to equipment intended to be operated and installed by qualified personnel in the field.
These requirements apply to control equipment used in or with movable engine driven assemblies that are otherwise constructed the same as stationary engine driven assemblies.
These requirements do not cover:
a) Distribution equipment which sole function is the automatic or nonautomatic transferring of one or more load conductor connections from one power source to another. In Canada the Standard for Transfer Switch Equipment is CSA C22.2 No. 178.1. In the United States it is the Standard for Transfer Switch Equipment, UL 1008.
b) Devices in the output power circuit, but would apply to pilot devices that monitor or control switching devices that control loads in power circuits.
c) Controls for the propulsion engine of a vehicle.
d) Independent equipment that does not perform any control function of an engine driven assembly or similar power production equipment control applications.
e) Equipment or devices for use in or connected to hazardous (Classified) locations.
f) Industrial Control Equipment for general use. In Canada the Standard for Industrial Control Equipment is CSA C22.2 No. 14. In the United States it is the Standard for Industrial Control Equipment, UL 508.
g) General Use Industrial Control Panels and Industrial Control Panel Assemblies other than power production. In Canada the Standard for Industrial Control Panels and Assemblies is CSA C22.2 No. 286. In the United States it is the Standard for Industrial Control Panels, UL 508A.
h) Equipment or devices for use in mobile applications.
