CMCP Field Application Note
Custom Cabinets and Panels
Cabinets and/or panels are available in many types,
sizes, colors and methods of construction. They 
can be
outfitted with many different accessories depending on your needs. In general, each
cabinet is custom engineered, to meet many different parameters. Care must be taken to
specify a cabinet or panel that meets all your needs and specifications. This application
note is provided as a guide to prepare a specification and needs to be provided along with
complete equipment listing of all systems being mounted in the cabinet.
Cabinet Location:
Cabinets are mounted either indoors or outdoors. Indoor cabinets can be mounted in a control, electrical or switchgear room. Outdoor cabinets may be mounted close to or on the machine deck exposed to the elements. Indoor cabinets are normally painted steel and meet Nema 12 requirements. Outdoor cabinets can be painted steel for Nema 4 or Stainless Steel for Nema 4x requirements.
Indoor
___ Outdoor Nema4___ Nema4___Environment:
Both indoor and especially outdoor cabinet environments need to be looked at for special environmental concerns and requirements. Temperature is a common issue for outdoor cabinets. Both the annual temperature extremes of the proposed cabinet location and the heat generating capacity of the equipment to be installed in the cabinet must be carefully looked at. Heating and/or Air Conditioning will be installed as required.

Type and Manufacture of Cabinet:
Cabinets come in two (2) basic types, Solid and Modular. Solid Cabinets have welded seams where modular cabinets are bolted together. Solid cabinets will be generally be used outdoors and modular cabinets indoors. In some cases a customer may have a preference between manufactures.
Solid
___ Modular___ Manufacture___________ Modular___ Manufacture___________Access:
The location that the cabinet is to be installed in needs to be looked at carefully as to access for maintenance and repair of the installed equipment. In general most cabinets have access front and rear. In some cases where a cabinet is to be mounted against a wall only side or front access is available. We always recommend Front and Back Access as any other type is difficult and expensive unless absolutely required. If side access is necessary, specify which side as if you are looking from the front.
Front & Back
Front & Back___ Front & L/R___ Front Only___Dimensions or Size:
Size is in the end determined by the installed equipment and required options. In most cases a desired size is specified and then will be changed, as engineering requires. Other existing cabinets and the desire to have the installed equipment close to eye height normally determine height. Height will normally be between 78" (2000 mm) and 82" (2100 mm). Width will be determined by available space and the installed equipment and will be 19" EIA, 24" (610 mm) or 36" (914 mm). Depth is determined by the depth of the installed equipment and will be either 26" (650 mm) or 34" (850 mm).

Power Distribution:
Power distribution is recommended and is usually provided. A power distribution panel with breakers and two (2) accessory power outlets will be provided. Lighting will be provided in the top of the panel for ease of maintenance. Top or Bottom power and wire entry to the cabinet needs to be specified along with input voltage.

Top___ Bottom___ 110 VAC___ 220 VAC___Intermediate Terminal Blocks:
Intermediate terminal blocks are a required feature on most cabinets. This allows for all the pre-wiring of the installed equipment to take place at the cabinet shop. Only power and external wiring need to be attached to the terminal blocks. A listing of the equipment to be installed, installed transducers, recorder outputs and required relays along with a percentage of spare terminal blocks to be supplied is required. As an alternate, direct wiring to the installed equipment can be accomplished.

Paint and Color:
The specific exterior paint color of the cabinet may be optionally specified to meet existing cabinet specifications or preferences. Any color other than standard OEM colors must be specified in advance. Non stock paints will effect price and lead times.
