NEXO ANALOGUE PSTD CONTROLLERS Page 47/82
To avoid electrical shock, do not remove covers.
Dangerous voltages exist inside.
Refer all servicing to qualified personnel only.
WARNING: To reduce the risk of fire or electric shock,
do not expose this apparatus to rain or moisture.
RISK OF ELECTRIC SHOCK
DO NOT OPEN
CAUTION
The lightning flash with arrowhead
symbol, within an equilateral triangle
is intended to alert the user to the
presence of uninsulated “dangerous
voltage” within the product's
enclosure that may be of sufficient
magnitude to constitute a risk of
electric shock to persons.
The exclamation point within an
equilateral triangle is intended to
alert the user to the presence of
important operating and
maintenance (servicing) instructions
in the literature accompanying
the appliance.
WARNING ! THIS APPLIANCE CLASS 1 APPARATUS AND MUST BE EATHED.
The green and yellow wire of the mains cord must always be connected to an
installation safety earth or ground. The earth is essential for personal safety as well as
the correct operation of the system, and is internally connected to all exposed metal
surfaces. Additional recommendation for interconnection to other equipment can be
found in the “Analogue TDcontroller Setting-Up Advice” section.
8.3 Analogue TDcontroller Setting-Up Advice
8.3.1 Mains Power
NEXO TDcontrollers don’t provide a mean to switch off the unit from the front panel. As they are
intended to be rack mounted the back panel is not accessible during use. Therefore it is left to the user
to provide a disconnection mean readily operable.
8.3.2 Voltage setting
NEXO TDcontrollers use a switch mode power supply (SMS12). This SMS12 accepts universal AC
power input voltages in the range 90V to 264V, and requires no manual adjustment for voltages in this
range.
8.3.3 Mounting the TDcontroller in a rack (Grounding, shielding & safety issues)
The TDcontroller is intended for rack mounting. The only accessible part during use shall be the front
panel of the TDcontroller. Any space above or under the TDcontroller shall be obstructed with a blank
panel.
The rack is a free grounding and shielding structure and it provides extra shielding. Therefore, it is
desirable that the screws used to fix the TDcontroller in the frame or rack provide an electrical contact
between the chassis of the TDcontroller and the rack.
The primary reason for grounding is safety. Conformance to the applicable requirements of the
authorities having jurisdiction is, of course, mandatory. However, grounding also has an impact on
electromagnetic compatibility. From the EMC point of view, it is desirable to have a low impedance
ground network, as a current flowing in the ground network will then produce low voltage in the network.
A low impedance network can be obtained using a multipoint ground scheme, with as many closed
ground looS12 as is economically possible.
8.3.4 Fuse
The fuse provided in the unit will not blow during normal operation. If the fuse blows the
TDcontroller has malfunctioned. This fuse must only be changed by NEXO certified
service personnel. In any case do not replace the fuse with a non-certified NEXO fuse, as
this will invalidate the NEXO warranty.
