Input Voltage Configuration – Models 112, 312LMX
WARNING
DISCONNECT
THIS UNIT FROM THE INPUT SERVICE AND ALLOW 15 MINUTES FOR INTERNAL
CAPACITOR VOLTAGES TO BLEED DOWN BEFORE REMOVING THE TOP COVER.
HIGH VOLTAGE HAZARD WILL BE PRESENT INSIDE THE UNIT WHEN TOP COVER IS REMOVED AND
STILL CONNECTED TO INPUT SERVICE
AVERTISSEMENT
DÉCONNECTEZ
CET APPAREIL DU SERVICE D'ENTRÉE ET PERMETTEZ 15 MINUTES POUR QUE LES
TENSIONS INTERNES DU CONDENSATEUR AURA ÉTÉ SAIGNÉE AVANT D'ENLEVER LE COUVERCLE
SUPÉRIEUR.
UN RISQUE DE HAUTE TENSION SERA PRÉSENT À L'INTÉRIEUR DE L'UNITÉ LORSQUE LE
COUVERCLE SUPÉRIEUR EST ENLEVÉ ET CONNEXION AU SERVICE D'ENTRÉE
The 112LMX and 312LMX Power Sources have been designed to accept most standard single
phase input voltage forms. This is accomplished through the use of a tapped, input power
transformer. Configuring the proper input form is a matter of setting jumpers in the
appropriate positions. The system is designed for use with input frequencies of 47 to 63 Hz.
(Optionally, the systems may be used with input frequencies of up to 440 Hz. Contact the
factory for details.)
Figure 5-3 shows the location of the various jumpers which need to be moved to change
input voltage form. The position of these jumpers is listed on the accompanying table.
To change the input power form, remove the top cover, then connect the jumpers as stated
in the table for the desired input voltage. Jumpers are located on the input power trans-
former (T1). Refer to the table in Figure 5-3 for the proper setting.
After configuring the input voltage form, check connections and ensure that they are tight
and in the correct position. Replace the top cover.
The Power Source can now be connected to an appropriate AC outlet via the input power
cord provided. Refer to Section 4.8 for minimum input service requirements of the various
input voltage forms.
