Important Safety Instructions
Before applying power to the system, verify that your product is configured properly for your application.
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 at a high voltage relative to chassis ground.
WARNING!
The equipment used contains ESD sensitive parts. When installing equipment,
follow ESD Safety Procedures. Electrostatic discharges might cause damage to the
equipment.
Only qualified personnel, who deal with attendant hazards in power supplies, are allowed to perform
installation and servicing.
Ensure that the AC input power line ground is connected properly to the unit safety ground chassis.
Similarly, other AC power ground lines, including those to application and maintenance equipment, must
be grounded properly for both personnel safety and equipment protection.
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 prevented.
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
and protective clothing during open cover checks to avoid personal injury by any sudden component
failure.
AMETEK Programmable Power Inc., San Diego, California, USA, or any of the subsidiary sales
organizations, cannot accept any responsibility for personnel, material or inconsequential injury, loss or
