SECTION 4
MISE EN GARDE!
Montage de l'appareil sur une surface verticale avec les fentes de ventilation sur les
côtés vers le haut / vers le bas n'est pas recommandé. Comme expliqué ci-dessus, il
s'agit d'éviter que (i) la chute d'objets dans l'unité à travers les fentes provoquant
un court-circuit ou (ii) en tombant de délogé / composants surchauffés fondu sur un
matériau combustible en cas de défaillance interne catastrophique.
4.5 AC SIDE CONNECTION
4.5.1 Connection for nominal AC input voltage of 120VAC (range: 100-130VAC),
50/60Hz (Factory preset condition)
The unit has been factory preset for nominal AC input voltage of 120VAC (range:100-
130VC), 50/60Hz.
120VAC power is fed to the unit through detachable, 120 VAC power cord supplied with
the unit. The power cord has the following specifications:
• Length of the cord: 6 ft
• Cable : 3 conductors (Line – black; Neutral – White; Grounding - Green), each
AWG #16
• 13A, 125V female connector "IEC 60320-C13" for power supply end.
Insert this end into the AC Power Inlet on the unit (2, Figs 2.1 / 2.2)
• 13A, 125V "NEMA5-15" plug for connecting to 120 VAC outlet
4.5.2 Connection for nominal AC input voltage of 230VAC (range: 200-260VAC),
50/60Hz (will require internal jumper setting)
The unit can also be operated from nominal AC input voltage of 230VAC (range: 200 to
260VAC), 50/60Hz by internal jumper setting, changing internal fuse size and changing
AC power cord as described below:
4.5.2.1 Changing internal jumper setting
a) Switch off the unit and unplug the AC power cord from the AC outlet supplying
AC power to the unit.
b) Remove the top cover by unscrewing 4 screws
c) For 120VAC operation (factory preset condition), points marked "C" and "E" on
the Printed Circuit Board (PCB) have been connected (shorted) with a flexible,
yellow colored jumper wire that has black colored Quick Disconnect Terminal
at the 2 ends. To convert to 230VAC operation, disconnect the Quick Connect
Terminal of the jumper wire at point "C" by pulling it upwards. Insulate this end
with insulation tape and use a cable tie to tie it securely to the nearby wire bundle.
4.5.2.2 Changing internal Fuse
a) For the factory preset 120 VAC operation, the internal AC input side Fuse is
rated at 250VAC, 8A. For 230VAC operation, remove this Fuse and replace with a
similar 250VAC, 4A Fuse (Littelfuse Part No. 0218004 or equivalent)
