WARNING

Hazardous voltages may be present when covers are removed. Qualified
personnel must use extreme caution when servicing this equipment. Circuit
boards, test points, and output voltages also may be floating above (below)
chassis ground.

WARNING

The equipment used contains ESD sensitive ports. When installing equipment,
follow ESD Safety Procedures. Electrostatic discharges might cause damage
to the equipment.

WARNING: Electrical Shock Hazard

HAZARD: Strong oxidizer

GENERAL WARNING/CAUTION: Read the accompanying message for

specific information.

BURN HAZARD: Hot Surface Warning. Allow to cool before servicing.

Do Not Touch: Touching some parts of the instrument without protection or

proper tools could result in damage to the part(s) and/or the instrument.

Technician Symbol: All operations marked with this symbol are to be
performed by qualified maintenance personnel only.

grounding point for the instrument.

IMPORTANT SAFETY INSTRUCTIONS

Before applying power to the system, verify that your product is configured properly for your particular
application.

Only qualified personnel who deal with attendant hazards in power supplies, are allowed to perform
installation and servicing.

Ensure that the AC power line ground is connected properly to the Power Rack input connector or chassis.
Similarly, other power ground lines including those to application and maintenance equipment must be
grounded properly for both personnel and equipment safety.

Always ensure that facility AC input power is de-energized prior to connecting or disconnecting any cable.
In normal operation, the operator does not have access to hazardous voltages within the chassis. However,

depending on the user’s application configuration, HIGH VOLTAGES HAZARDOUS TO HUMAN SAFETY
may be normally generated on the output terminals. The customer/user must ensure that the output power
lines are labeled properly as to the safety hazards and that any inadvertent contact with hazardous voltages is
eliminated.

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 may retain an electrical charge. Use safety glasses during open
cover checks to avoid personal injury by any sudden component failure.

Neither AMETEK Programmable Power Inc., San Diego, California, USA, nor any of the subsidiary sales
organizations can accept any responsibility for personnel, material or inconsequential injury, loss or damage
that results from improper use of the equipment and accessories.

ABOUT THIS MANUAL

This manual has been written expressly for the Sorensen ASD Series of
power supplies that have been designed and certified to meet the Low
Voltage and Electromagnetic Compatibility Directive Requirements of the
European Community.

These models have been designed and tested to meet the Electromagnetic
Compatibility directive (European Council directive 2004/108/EC; generally
referred to as the EMC directive) and to the requirements of the Low Voltage
directive (European Council directive 2006/95/EC, 93/68/EEC, dated 22 July

1993). In addition these models have been found compliant with FCC 47
CFR Part 15, Subpart B 107(e) Class A, 109(g) Class A.

Since the Low Voltage Directive is to ensure the safety of the equipment
operator, universal graphic symbols have been used both on the unit itself
and in this manual to warn the operator of potentially hazardous situations
(see Safety Notice page).
