SUPPLEMENT #l

FOR INSTRUCTION MANUAL GEK-85714A

These instructions do not purport to cover all details or variations in equipment, nor to provide for every possible contingency to be met during installation, operation, and maintenance. Should &rther information be desired or should particular problems arise that are not covered suficiently for the purchaser’s purpose, the matter should be referred to GE Drive Systems, Salem, Virginia U.S.A.

This supplement contains additional information needed when installing and operating the AF-300A series of inverters. Refer to the information of this supplement in addition to that contained in GEK85714A for the figures, tables, and paragraphs listed in this supplement.

Table 3: Application of Wiring and Equipment

The recommended wire sizes shown in Table 3 are minimum sizes. Due to variations in installation, check that the recommended wire sizes are adequate for that particular installation. All inverter installations must meet the applicable national (NEC, CEC) and local electrical codes. It is the system engineer’s responsibility to be certain that the inverter installation complies with all applicable electrical codes. (If a system engineer is not involved, it is the user’s responsibility.) Only adequately trained persons should install any programmable inverter.

Figure 4-6. Basic Connection Diagram

The 3-phase AC circuit breaker shown in this figure is incorrectly illustrated as three breakers. It is actually a single, 3-pole breaker.

Figure 4-6. Basic Connection Diagram Figures 8-4 and 8-5. Control Block Diagrams

Thermal Relay shown in theses figures is not a standard option kit available from General Electric Drive Systems. Overload protection is not provided by the AF-300A and therefore must be provided by the user. (Typical thermal relay circuit wiring is shown in Figure 4-6.) All inverter installations must meet the applicable national (NEC, CEC) and local electrical codes. It is the system engineer’s responsibility to be certain that the inverter installation complies with all applicable electrical codes. (If a system engineer is not involved, it is the user’s responsibility.)

Table 10: AC Line Fuses and Fuseholders

Due to variations in installation when mounting fuseholders and fuses external to the inverter, check that the recommended fuse sizes are correct for that particular installation. When using the recommended fuse sizes, overload protection must be provided by the user in order to comply with most electrical codes. All inverter installations must meet the applicable national (NEC, CEC) and local electrical codes. It is the system engineer’s responsibility to be certain that the inverter installation complies with all applicable electrical codes. (If a system engineer is not involved, it is the user’s responsibility.)

IDENTIFICATION, AND SPECIFICATIONS,

GENERAL DESCRIPTION

The AF-300ATM inverter is available in l/4 to 5 HP, 200230 VAC 3-Phase and l/4 to 3 HP, 200-240 VAC

Single-Phase versions. The output of the inverters is 3-phase for running a 3-phase motor whether the input is single-phase or 3-phase. All of the inverters use 32-bit “Digital Signal Processors” (DSP) for muttifunction processing to provide high performance in all applications. completely enclosed (except for the cooling fan) construction for improved performance in adverse environments. All the inverters are furnished with

detachable wiring lead-in plate for access so that wiring can be easily accomplished. (See Figure 2-3 for inverter external component identification.)

lnverter operation and code function setting is

performed from the “Keypad Panel” that features a 3-

Position, 7-segment LED display. Five operation

keys: STOP key, Program (Shift) Key, RUN Key, and

the Increment and Decrement Keys (for frequency/

speed adjustment) control the inverter. (See Figure

2-2 for Keypad Panel component identification and

function.)

The AF-300A inverters feature

General data and specifications for each individual inverter are listed on the nameplate attached to the inverter (see Figure 2-l for nameplate example). See

TABLE 1 for a complete listing of all AF-300A inverter

specifications,

INSPECTION ITEMS UPON DELIVERY

Upon receipt of your inverter, inspect equipment for

the following items:

1. Check the nameplate to insure that the specifications correspond to those ordered.

2. Inspect the unit for any damage that may have occurred during shipment.

-- If there are any problems or questions regarding

the above, contact the distributor from which the inverter was purchased.
