SAFETY INSTRUCTIONS
CAUTION: The following safety precaution must be observed during all phases of operation, service and repair of
this equipment. Failure to comply with the safety precautions or warnings in this document violates safety standards
of design, manufacture and intended use of this equipment and may impair the built-in protections within. TDK
Lambda shall not be liable for user's failure to comply with these requirements.
CAUTION: RFE1000 units are not authorized for use as critical component in nuclear control systems, life support systems or
equipment for use in hazardous environments without the express written approval of the managing director of TDK-Lambda.
INSTALLATION (OVERVOLTAGE) CATEGORY& ENVIRONMENTAL CONDITIONS
The RFE1000 units have been evaluated to Overvoltage category II.
The RFE1000 units intended for use in the following operation conditions:
* Indoor use * Pollution degree 2 * Max. operational altitude: 3000m above sea level
*Ambient temperature: -10°C-50°C at 100% load, up to 70°C with output de-rating applied (See Specification)
GROUNDING
RFE1000 units are Class I products. To minimize electrical shock hazard, the RFE1000 units must be connected to an
electrical ground. The instruments must be connected to the AC power supply mains through a three conductor power
cable, with the ground wire firmly connected to an electrical ground (safety ground) at the power outlet. For instruments
designed to be hard-wired to the supply mains, the protective earth terminal must be connected to the safety electrical
ground before any other connection is made. Any interruption of the protective ground conductor or disconnection of the
protective earth terminal will cause a potential shock hazard that might cause personal injury.
In addition, a screw through the end-equipment's chassis to the power supply chassis must be fastened that would
connect the power supply to an electrical ground, refer to figure 2-1. This ground-dedicated screw must be other than the
mounting screws, must not serve as a means to fix any other component, and must be free of any glue or coating in order
to secure a solid and reliable connection. In case of doubt, earthing test (resistance of the protective bonding system) shall
be conducted to verify reliability of connection to the earthing system of the equipment.
To properly conduct this earthing test, stream an electric current with a magnitude of 40 A DC or AC, and the test voltage
shall not exceed 12 V, for a duration of 2 minutes between the head of the earthing screw and any other accessible
conductive part on the power supply. Compliance criteria shall be that the resistance of the protective bonding system,
calculated from the voltage drop, shall not exceed 0.1Ω.
The ground cable connected to the permanent connection must meet the Dimensions of the wires: RFE1000 - 14AWG.

LIVE CIRCUITS
Operating personnel must not remove
the RFE1000 units cover. No internal
Load
adjustment or component replacement
is allowed by non-TDK Lambda qualified
service personnel. Never replace
components with power cable connected.
To avoid injuries, always disconnect
power, discharge circuits and remove
external voltage sources before touching
components. Restricted Access Area:
RFE1000 units should only be installed in a
Restricted Access Area. Access should be
available to service personnel only.
