. ASME Code requires that the temperature within an elevator equipment room be maintained between 55 and 110 degrees F non-condensing. Minimum standards for machine room enclosures. In some cases it may require a means to test the shunt trip operation or have one contact operate the shunt trip of more than one elevator.

Cab width for side opening doors is at least 68. The system shall be capable of maintaining temperatures within the. These regulations are not intended to supersede applicable local building codes establishing higher standards.

It need not be exactly centered on the equipment and working spaces of adja-cent pieces of equipment may overlap. Elevator machine rooms machinery spaces that contain the driving machine and control rooms or spaces that contain the operation or motion controller for elevator operation shall be provided with an independent ventilation or air-conditioning system to protect against the overheating of the electrical equipment. All of these options and special wiring can be challenging depending upon the.

The basic requirement is for minimum clear distances of various depths for equipment operating at 600 V or less nominal depending upon voltage to ground and lateral distance to insulated or grounded surfaces or exposed live parts not an issue in elevator machine rooms. Schumacher Elevator Company Subject. Live parts not an issue in elevator machine rooms.

This is typically accomplished by a shunt-trip device. Where machine rooms are provided the disconnecting means required by 62051 shall be located within 610 mm 24 inches of the open side of the machine room access door.
