TDK-Lambda HFE2500-S1U Instruction Manual - page 3
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: HFE2500-S1U rack is 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 HFE2500-S1U has been evaluated to Overvoltage category II.
The HFE2500-S1U 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 (refer to Specification above).
GROUNDING
HFE2500-S1U rack is Class I product. To minimize shock hazard, the HFE2500-S1U rack 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.
LIVE CIRCUITS
Operating personnel must not remove the HFE2500-S1U rack cover.
No internal 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: HFE2500-S1U rack should only be installed in a Restricted Access Area. Access should be available to service
personnel only.
PARTS SUBSTITUTIONS & MODIFICATIONS
Parts substitutions and modifications are allowed by authorized TDK Lambda service personnel only. For repairs or modifications, the
instrument must be returned to TDK Lambda service facility.
AC INPUT, AC INPUT RATING, AC POWER CABLES
CAUTION
Risk of electrical shock and energy hazard. Disconnecting one
power supply line disconnects only one power supply module.
To isolate the unit completely, disconnect all power supply
lines. Terminal blocks should only be used by professional
workers to connect AC cables.
ACHTUNG
Spannungsführende Teile - Gefahr durch elektrischen Schlag
order hohe Energieinhalte. Alle Netzstecker der einzelnen
Komponenten bzw. der Einschübe müssen getrennt werden,
damit das System “spannungsfrei” ist.
Die Eingangsklemme der Stromversorgung ist nur innerhalb
eines Gesamtsystemes zu verwenden.
ATTENTION
Risque de choc et de danger e’lectriques. Le de’branchement
d’une seule alimenttation stabilise’e ne de’branche
uniquement qu’un module “Alimentation Stabilise’e”.
Pour isoler completement le module en cause, il faut
de’brancher toutes les alimentations stabilise’es.
Do not connect HFE2500-S1U to mains supply exceeding the input
voltage and frequency rating of HFE2500-S1U. The input voltage
and frequency rating is: 100-240V~, 50/60Hz. For safety reasons,
the mains supply voltage fluctuations should not exceed +/-10% of
nominal voltage.
AC Cables are not provided with unit. Refer to table below for recommended AC cables.
HEAT HAZARD
WARNING: Top, bottom and side surfaces may become hot when operating the unit continuously. To reduce the risk of injury from a
hot surface, allow the surface to cool before touching.
ENERGY HAZARD
The main output of HFE2500-S1U is capable of providing hazardous energy. Due to hazardous energy level the output bus bars and
connections therefore must not be user accessible. Manufacturer’s final equipment must provide protection to service personnel
against inadvertent contact with output bus bars.
