ASME A17.5:1996 pdf download Elevator and Escalator Electrical Equipment
1. Scope
1.1
These requirerments apply to drive machine controllers, logic controllers, and operating devicesaccessory thereto, for starting, stopping, regulating, controlling, or protecting electric motors,generators, or other equipment, for elevators, escalators, moving walks, dumbwaiters, and elevatingdevices for the handicapped (wheelchair and stairway lifts).
1.2
The electrical equipment is intended to be connected to supply circuits at a nominal system yoltage of600 Y or iess, and for internal voitages at not more than 1500 V, and for use in nonhazardous locationsin accordance with the rules of the applicable electrical codes.
1.3
These requirements exclude any equipment specifications already covered by an applicable elevator orelevating device code.
1.4
The object of this Standard is to reduce the risk of injury to persons and damage to property from fireand electrical shock by presenting requirements for proper design, good construction, and high qualityworkmanship of the equipment listed in Clause 1.1. To this end, this is a safety standard for the designand construction of equipment to be used in conformity with the rules of the applicable elevator and
electrical codes.
1.5
This Standard dues not apply to devices that are rated for connection to extra low voltage Class 2supply circuits as defined in the applicable electricai code.Note: Extra low voltage circuits are circuits that have a yoltage of not more than 30 V rms or 42.4 V peak.
1.6
The interpretation of clauses depends on the correct interpretation of the words “shall”, “should”, and”may”，”Shal!” is mandatory; “should” is recommendatory; “mayis permissive.
1.7
Metric (S) units are the primary units of measure in this Standard. The lmperial units in the text havebeen directly (soft) converted from the Sl units.
