WARNING! HAZARDOUS VOLTAGES IN EXCESS OF 280 VRMS, 600V PEAK MAY BE PRESENT WHEN COVERS

4、ARE REMOVED. QUALIFIED PERSONNEL MUST USE EXTREME CAUTION WHEN SERVICING THIS EQUIPMENT. CIRCUIT BOARDS, TEST POINTS, AND OUTPUT VOLTAGES MAY BE FLOATING ABOVE (BELOW) CHASSIS GROUND. Installation and service must be performed by qualified personnel who are aware of dealing with attendant hazards. T

5、his includes such simple tasks as fuse verification. Ensure that the AC power line ground is connected properly to the DCS Series unit input connector or chassis. Similarly, other power ground lines including those to application and maintenance equipment must be grounded properly for both personnel

6、 and equipment safety. Always ensure that facility AC input power is de-energized prior to connecting or disconnecting the input/output power cables. During normal operation, the operator does not have access to hazardous voltages within the chassis. However, depending on the users application confi

7、guration, HIGH VOLTAGES HAZARDOUS TO HUMAN SAFETY may be generated normally on the output terminals. Ensure that the output power lines are labeled properly as to the safety hazards and that any inadvertent contact with hazardous voltages is eliminated. To guard against risk of electrical shock duri

8、ng open cover checks, do not touch any portion of the electrical circuits. Even when the power if off, capacitors can retain an electrical charge. Use safety glasses during open cover checks to avoid personal injury by any sudden failure of a component. Due to filtering, the unit has high leakage cu

9、rrent to the chassis. Therefore, it is essential to operate this unit with a safety ground. Some circuits are live even with the front panel switch turned off. Service, fuse verification, and connection of wiring to the chassis must be accomplished at least five minutes after power has been removed

10、via external means; all circuits and/or terminals to be touched must be safety grounded to the chassis. After the unit has been operating for some time, the metal near the rear of the unit may be hot enough to cause injury. Let the unit cool before handling. Qualified service personnel need to be aw

11、are that some heat sinks are not at ground, but at high potential. These operating instructions form an integral part of the equipment and must be available to the operating personnel at all times. All the safety instructions and advice notes are to be followed.
