Splices between terminations are not permitted. Connections and terminals shall be supported and spaced without the dependence upon the wiring in the components and braced as necessary to assure withstanding the distortion forces associated with available short-circuit currents. Proper identification of wiring, bussing, terminals and circuits for function, polarity, phasing, etc., shall be adhered to throughout the equipment. Identification shall be in the form of wire markers, color coding, permanently engraved plates, and permanent markings on the devices. Adequate spacing shall be maintained throughout to avoid excessive bending of cabling and wiring, to maintain adequate separation and creepage distance between electrical potentials and between these potentials and ground, and to permit ease in disconnecting wiring and cabling during trouble-shooting and repair. In no instance shall clearances and creepage distances be less than those described under NEMA ICS, Part ICS 1-111.

Grounding. Exposed, non-current carrying metal parts shall be maintained at common, zero ground potential. A grounding stud/lug shall be provided as a means for grounding the equipment. For cord connected equipment, a NEMA type grounding plug which effectively grounds the equipment for the safety of personnel shall be acceptable in lieu of a ground stud or lug on the equipment.

Electrical Enclosure. Electrical components of the equipment shall be contained in an enclosure(s) of structural and sheet steel. Provisions shall be made for power cable entrance. The enclosure(s) shall be of drip-proof construction and of minimum size consistent with good design practices and ventilation of components.

Emergency Stop Buttons. The equipment specified herein shall be provided with emergency stop buttons (switches) at the equipment control panel. These stop buttons shall be the mushroom type, shall be colored red with a yellow background, and shall be labeled as such. When activated, the emergency stop buttons shall disconnect all electrical power to the equipment such that all operations or functions will immediately stop or cease.

Hydraulic Systems. Hydraulic systems shall include filtration, protection from over pressurization, and comply with requirements of ISO 4413. The system shall be complete, including all pumps, valves, piping, cylinders, and pressure controls. Overpressure protection shall be provided to prevent damage to components and fluid conductors. A filter system shall be provided to insure delivery of clean fluid to the system. Where ventilation of the hydraulic unit is necessary for lubrication or hydraulic purposes, tall vents shall be filtered and located in a position that will prevent contamination or loss of lubricant. The hydraulic pump inlet shall be protected with an inlet strainer. Reservoirs used for lubrication or hydraulic fluid, shall have a means of visually determining fluid level, temperature and over pressurization, as well as a drain plug for routine maintenance and cleaning. All reservoirs used as a holding tank, shall be tested and certified to prevent leakage. Lubrication and hydraulic systems having reservoirs located in the bed or base shall have filters mounted outside the bed or base to facilitate maintenance and prevent inadvertent contamination. A positive means of fluid temperature control shall be provided to prevent the system from exceeding 130°F under normal operating conditions.

Painting. All surfaces shall be painted in conformance with the manufacturer’s standard practices and good workmanship. Painting shall result in a highly wear-resistant finish that guarantees continued protection to surfaces in an indoor environment with a temperature range of 15 to 110 F, up to 100% Non-condensing relative humidity. The manufacturer’s standard color shall be provided. Lead or chromium base paints are prohibited.
