Safety Notes - TDK-Lambda DPP480-XX-3 Installation And Operation

Safety notes

Read Instructions!
Before working with this unit, read these instructions carefully
and completely. Make sure that you have understood all the
information!
Disconnect system from supply network
Before any installation, maintenance or modification work:
Disconnect your system from the supply network. Ensure that
it cannot be re-connected inadvertently!
Before start of operation
Ensure appropriate installation
Warning! Improper installation / operation impair safety and
result in operational difficulties or complete failure of the unit.
The unit must be installed and put into service appropriately
by qualified personnel. Compliance with the relevant
regulations must be ensured.Before operation is begun the
following conditions must be ensured, in particular:
Connection to main power supply in compliance with
VDE01000 and EN50178.
With stranded wires: all strands must be secured in the
terminal blocks (Potential danger of short circuit).
Unit and power supply cables must be properly fused; if
necessary a manually controlled disconnecting element must be
used to disengage from supply mains.
The non-fused earth conductor must be connected to the
" " terminal (protection class 1).
All output lines must be rated for the power supply output
current and must be connected with the correct polarity.
Sufficient air-cooling must be ensured.
pollution degree 2 environment.
In operation: No modifications!
As long as the unit is in operation: do not modify the
installation! The same applies also to the secondary side.
Risk of electric arcs and electric shock (fatal)!
Only (dis) connect plug connectors when
the power is off!
Convection cooling (See Fig. 1)
Do not cover any ventilation holes!
Leave sufficient space around the unit for cooling!
Warning: High voltage! Store energy!
The unit contains unprotected conductors carrying a lethal
high voltage, and components storing substantial amounts
of energy. Improper handling may result in an electric shock
or serious burn!
The unit must not be opened except appropriately trained
personnel!
Do not introduce any object into the unit!
Keep away from fire and water!
Installation
Application
This unit is a primary switched-mode power supply designed
for use in panel-board installations or building-in
applications where access to the supply is restricted (shock-
hazard protection). It must only be installed and put into service
appropriately by qualified personnel.
Mounting
Mounting (See Fig. 1)
Permissible mounting position: keep free ventilation hole, leave
space for cooling! Recommended to have 25mm free space
at all sides for ventilation / cooling:
Snap on support rail (See Fig. 2)
Tilt the unit slightly rearwards.
Fit the unit over top hat rail.
Slide it downward until it hits the stop.
Press against the bottom front side for locking.
Shake the unit slightly to check the locking action.
Front elements
Operation indicator
Indicates whether the unit is working properly. Green LED is
lit on if the voltage at the output terminal is more than 75%.
DC output low indicator
Red LED is lit when the voltage at the output terminal is 70%
to 90% of the rated output voltage.
Potentiometer
Used to set the output voltage.
All specifications are typical at norminal line, full load,

Connection (See Fig. 3)
Data for permitted loads, cable cross-sections and stripping:
Use only commercial cables designed for the indicated
voltage and current values!
With flexible cables: make sure that all stranded cable are
secured in the terminal.
Ensure proper polarity at output terminals!
Grounding
Do not operate without PE connection! To comply with
EMC and safety standards (CE mark, approvals), the unit
must only be operated if the PE terminal
the non-fused earth conductor.
Secondary side is not earthed; if necessary the
terminal can be earthed optionally.
Internal fuse
The internal input fuse serves to protect the unit and must
not be replaced by the user. In case of an internal defect, the
unit must be returned to the manufacturer for safety reasons.
External circuit breaker
For input line protection observe national regulations; recommended
recommended circuit breaker: Mitsubishi, Type NF30-CS, rated
20A max or equipollent of TUV/VDE/UL approved sources.

Removal
from DIN Rai
Insert a flat screwdriver into the slot in the clamp. Pull the
clamp down until it clicks off the Din rail, then, from the
bottom, lift the power supply up and away.
