User manual

CAUTION:

Before connecting the line cord to the AC mains, check the rear panel AC line voltage

indicator

. Applying a line voltage other than the indicated voltage can destroy the AC line

fuses. For continued fire protection, replace fuses only with those of the specified voltage

and current ratings.

CAUTION:

This product uses components which can be damaged by electro-

static discharge (ESD).

To avoid damage, be sure to follow proper procedures for handling, storing and

transporting parts and subassemblies which contain ESD-sensitive components.

WARNING

HAZARDOUS VOLTAGES IN EXCESS OF 230 Vrms, 400 V peak MAY BE PRESENT WHEN

COVERS ARE REMOVED.QUALIFIED PERSONNEL MUST USE EXTREME CAUTION WHEN

SERVICING THIS EQUIPMENT. CIRCUIT BOARDS, TEST POINTS, AND OUTPUT VOLTAGES

MAY ALSO BE FLOATING ABOVE (BELOW) CHASSIS GROUND.

CAUTION:

Before applying power verify that the product is set to match with the line voltage. Ensure that the AC

power line ground is properly connected to the AC Source input connector. Similarly, other power

ground lines including those to application and maintenance equipment MUST be properly grounded for

both personnel and equipment safety.

Always ensure that AC input power is de-energized prior to connecting or disconnecting the power

cable. Similarly, the AC Source mains switch must be switched OFF prior to connecting or

disconnecting LOADS.

In normal operation, the operator does not have access to hazardous voltages within the chassis.

However, depending on the application configuration, HIGH VOLTAGES HAZARDOUS TO HUMAN

SAFETY may be normally available on the output terminals if it is connected to a load. The User must

ensure that the Source Output lines are properly labeled as to the SAFETY HAZARDS and any that

inadvertent contact with hazardous voltages is eliminated.

For authorized service technicians only: Guard against risks of electrical shock during open cover

checks by NOT TOUCHING any portion of the electrical circuits. Even when power is OFF, capacitors are

well known to retain an electrical charge. Please allow sufficient time for discharge of storage elements

before opening the cover. Use SAFETY GLASSES during open cover checks to avoid personal injury by

any sudden component failure.

Always replace the fuse with the appropriate rating only. Do not operate the instrument in the presence

of flammable gases or fumes.
