2 PRE-INSTALLATION CHECKLIST
This chapter can be used as a checklist to verify all the steps necessary to complete
installation of the PWR power supply.
CAUTION:
Opening the cabinet requires a key that should be used by a
person adequately advised or supervised by an electrically skilled person to
enable him or her to perceive risks and avoid hazards which electricity can
create. Internal components guarantee an IP20 degree of protection against
direct contact.
1) Read all information in this manual before installation, paying particular attention to all
Caution and Warning notes.
2) Mount the PWR to the Station frame using the brackets and bolts provided in the
package. See par. 3.1.
SYSTEM WIRING: DC OUTPUT
3) Plan all the cable entry points to avoid unnecessary holes and pass the cables through
the Cable Entry Plate as described in par. 4.
4) Connect your devices to the PWR according to the information in par. 4.2.
SYSTEM WIRING: AC INPUT
5) To comply with EN 60950-1:2007 par.1.7.2.2, par. 2.7.1, par 2.7.4, par. 3.4.6, and to
protect the AC input connection to the device; a disconnecting device with built in
overcurrent and earth protection shall be installed external to the equipment according
to local regulations.
According to EN 60950-1:2007 par. 3.2.3; the AC input cable must have a maximum
diameter of 14mm and the conduit a max diameter of 16mm.
6) With AC line voltage OFF, wire the AC Line to the AC Line Input Terminal Block (see
par. 5).
SYSTEM WIRING: TEST
7) Apply the AC line voltage from the building installation or the DWS-SWITCH and check
that the PWR powers up correctly. The green DC-OK light should be on steady and the
overload light (red) should be off.
8) Close and lock the PWR enclosure and check that it does not open (lock functions
correctly).
The PWR-480W installation is now complete.
