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

CAUTION:

The contrd circuit terminal wiring should

be kept as far awav as possible from the main power wirino to prevent operational error due to noise interference. Never install both tvpes of wiring in the same duct or conduit. (A separation distance of 10 centimeters [4 inches] or more is recommended.) If the control circuit wiring must cross the main power wiring, it should cross at a right angle.

CAUTION:

Use shielded or twisted wire for the

control circuit wiring (wiring should be as short as possible, i.e. 20 meters 165 feet] or less). (Connect outer covering of the shielded wires to the inverter ground terminal and leave the other end open, but taped.)

CAUTION:

Install a suppressor in parallel with any

relays or solenoid type coils, etc. that may be close to the inverter.

3. Use a high resistance range type tester to conduct a continuity test on the control circuits and not a megger or a buzzer.

PERIODIC PARTS REPLACEMENT

The life of the inverter will vary according to the installation environment and the amount of running

time. However, if continuous operation is within the

allowable limits, the life of the DC Link capacitor is approximately five years and the life of the cooling fan is approximately three years. It is recommended that these parts be replaced before failure occurs.
