Section 7 MAINTENANCE and INSPECTION To prevent potential problems and provide long periods of trouble-free operation, the following checks should be periodically conducted. CAUTION: Do not conduct any inspections until after disconnecting the power supply and after the “CRG” light on the Drive has gone out. MEGGER TEST 1. Disconnect all Drive terminals and never apply test voltage to the Drive when conducting an external circuit megger test.
INSPECTION ITEMS Refer to the Inspection Items Chart in this section for inspection points and corrective action. INSPECTION ITEMS CHART Item Inspection Criteria Corrective Action Power Supply Voltage Within permissible limits (170-264 Vac) for 1 Phase 240 VAC Drives; (170-253) for 3 Phase 230 VAC Drives; and (323-528) for 3 Phase 480 Vac Drives. Adjust the power supply voltage. Ambient Temperature Within permissible limits (-10° to +50° C) (+14° to +122°F.
MEASUREMENT POINTS AND METERS Since the Drive's input/output voltage and current contain high frequencies, selection of the wrong measuring device can lead to gross miscalculations. When using a CT (current-detection transformer) to measure the current, the amount of error will be large if the frequency is low. Because of this, always use a CT with as large a capacity as possible. See the following chart and Figure 7-2 for recommended measurement devices.
