Warning: Before any adjustments, servicing, parts replacement or any other act is performed requiring physical contact with theelectrical working components or wiring of this equipment, all power must be removed and locked off from all sources and all attachedrotating equipment must have come to a complete stop. User personnel must be completely familiar with the following operating andmaintenance instructions before attempting to service this equipment.

IntroductionThe CR7160 Limitamp® Controller, a quality GE product,was designed and manufactured to give long and satisfactoryservice. This bulletin contains items that, through normal use,may require periodic replacement; other items may neverneed service or replacement during the useful life of theequipment.
High-Voltage Contactor NameplateHigh-voltage contactor renewal parts are found in separaterenewal parts publications depending on the contactor cata-log number. This catalog number is found on the contactornameplate mounted on the steel bracket directly above thecontactor coil. An example of this nameplate is shown below:

Limitamp® Medium Voltage Motor Control
Limitamp Panel Data NameplateThis nameplate is mounted near the starter handle operatoron the high-voltage door. It contains all the necessary infor-mation for the factory to positively identify the starter and itsbill of material. This information must accompany all partorders and quotation requests. An example of this nameplateis shown below:
Catalog Numbering SystemLimitamp control is manufactured in three constructiontypes: one-high, two-high and three-high. One-high construc-tion consists of one medium-voltage contactor in one 90-inch-high enclosure. Two-high construction contains two medium-voltage contactors in one 90-inch-high enclosure. Three-highconstruction has three medium-voltage contactors in one 90-inch-high enclosure.
You should first determine the construction type (one-high,two-high or three-high) of your equipment. After determina-tion, the following pages should be consulted:
Pages 4 and 5 for one-high constructionPages 6 and 7 for two-high constructionPages 8 and 9 for three-high construction

Another method of identifying construction is through thecontroller “CR” number (shown on the panel data name-plate) . Example: Catalog Number 7160A118G. The alphasuffix determines one-high, tiuo-high or three-high; G is one-high,K is two-high and H is three-high. Vacuum starters are designatedby an M suffix. Example: Catalog Number 7160A118GM .

Figure 2. Limitamp Panel Data Nameplate
The required information is the catalog number and thediagram number. The catalog number from the sample aboveis 0607X0431V02 A01. The number can be broken down asfollows: 0607X0431 is the material list number or shop ordernumber for the job, V02 is the overall lineup designation, andA01 is a section in that lineup. The diagram number identifiesthe group of drawings that pertain to this particular projectorder.
Sections that do not have a panel data nameplate will have acompartment nameplate mounted on the right side doorflange. An example is shown below:
Figure 3.LimitampCompartmentNameplate
This will provide the catalog number only. The diagramnumber can be obtained from any Panel Data Nameplate onthat lineup.

Handle Assembly Some parts of the handle assembly are replaceable and can beidentified by part number as shown below:
V
The non-load break isolating mechanism (handle assembly) isa complex construction requiring a special bench fixture toassemble and adjust the mechanical interlocking mechanisms.Therefore, we recommend the entire assembly be replaced ifthe handle mechanism becomes extensively damaged.

'0' •§-Entire assemblies are ordered by catalog number 116C9928G*(see Tables 6 and 7). The group number (G*) is found on anadhesive backed label stuck on the underside of the handlehousing (see Figure 12). For G51, G52 and G55, orderreplacement assemblies Gl, G2 and G5 respectively.

A one-high vertical bus assembly consists primarily of the busbars, shutter, and operator assembly all constructed as oneitem. The complete assembly is the easiest to replace; howev-er, if the user has the expertise, the bare bus bar assembly canbe installed in the field. The following table is a cross refer-ence from the complete assembly group number,
.194A4480G*, to the bare bus bar assembly, 116C992_G_,shown in the following table.
