TDK-Lambda FPS-T1U Installation Manual page 24

PARTS SUBSTITUTIONS & MODIFICATIONS
Parts substitutions and modifications are authorized TDK Lambda service personnel only. For repairs or modifications, the
instrument must be returned to TDK Lambda service facility.
AC INPUT
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.
ENERGY HAZARD
The main outputs of FPS-T1U units are capable of
providing hazardous energy. Due to hazardous energy
level the output 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.
SERIAL OPERATION
The FPS-T1U product is capable of providing hazardous
voltage (more than 60VDC) output in case of the serial
connection of two or more FPS1000 units in the rack.
Therefore if the output sets such that hazardous voltage
occurs the manufacturer final equipment must provide
protection to service personnel against inadvertent contact
with output terminals. Moreover if the output(s) sets such
that hazardous voltage occurred it must not be user
accessible.
FUSE
There are no fuses in the FPS-T1U rack.
OVERCURRENT PROTECTION:
FPS-T1U Without suffix /TB
A readily accessible branch circuit over-current
protective device rated 20A max. per each input must be
incorporated in the building wiring.
Protective cunductor current:
Caution High touch current - the protective conductor
(PE) should be connected first to main protective earthing
terminal before connecting the line and neutral to avoid
shock hazard, and that a PE connection to the main PE
terminalis essential before connecting to the mains to
avoid electric shock.

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 FPS-T1U units to mains supply exceeding
the input voltage and frequency rating. 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.The leakage current of the end use
equipment not exceed 3.5mA.
Multiple power source:
Caution Shock hazard -all power sources shall be
disconnected before servicing to avoid shock hazard."
SYMBOLS
CAUTION Risk of Electrical Shock.
Instruction manual symbol. The instrument will be
marked with this symbol when it is necessary for the
user to refer to the instruction manual.
Indicates hazardous voltage.
Indicates ground terminal.
Protective earth; protective ground. Indicates the
terminal which is intended for connection to an
external conductor for protection against electric
shock in case of a fault.
Denotes hazard. An attention to a procedure
is called. Not following the procedure correctly
could result in personal injury. A WARNING
sign should not be skipped and all indicated
conditions must be fully understood and met.
