5.1 AC Voltage Connections

THE CHARGER DC OUTPUT SHOULD NOT BE CONNECTED TO A BATTERY DURING INSTALLATION

OF THE AC INPUT POWER CONNECTIONS AND DURING INITIAL AC POWER UP.

To connect the input AC voltage, route the AC supply wiring in conduit through the conduit hole in the floor of the charger case. Route the AC wiring to the terminal lugs of the fuse holder located below the AC fuses labeled F1 and F2 (single-phase) or above the AC fuses labeled F1, F2, and F3 (three-phase). For proper connections, torque the terminal lug screws to the “Terminal Lug Torque” shown in Figure 5.1-1 below.

Figure 5.1-1: AC Input Torque Specifications

WARNING: IMPROPERLY CONNECTED AC VOLTAGE CONDUCTORS CAN CAUSE AN

ELECTRICAL FIRE.

Connect the AC ground to the terminal lug located below the AC fuses on the base floor (single-phase).

WARNING: DO NOT OPERATE THE CHARGER WITHOUT PROPER GROUNDING. IMPROPER

GROUNDING CAN RESULT IN THE RISK OF AN ELECTRIC SHOCK.

5.2 AC Voltage Jumper Positions

The charger is factory wired for the AC input voltage (AC VOLTS) listed on the ratings label. Contact your charger dealer to have the AC voltage jumper positions changed for a different AC input voltage.

DOCUMENT ANY CHANGES ON THE RATINGS LABEL ON THE FRONT OF THE CHARGER OR ON

AN ADDITIONAL LABEL OR TAG.

5.3 AC Fuses

The correct fuses for the factory wired AC input voltage were installed at the factory. If the AC input voltage is changed, it may be necessary to change the AC input fuses. Contact your charger dealer to have the AC voltage wiring changed and obtain the proper fuses.

USE ONLY THE CORRECT SIZE IDENTICAL TYPE REPLACEMENT FUSES. FUSES ARE AVAILABLE

FROM YOUR DEALER’S QUALIFIED SERVICE TECHNICIAN.

5.4 Initial AC Power Up

The charger DC output should not be connected to a battery during initial AC power up. After applying AC power to the charger, it will execute a test routine. The routine takes approximately 15 seconds to complete.

Do not connect the charger DC output to a battery until this routine is complete.

If the routine executes successfully, the Voltage and Battery Type String (for example “24VW”) will be shown on the main display, indicating that the charger is ready to be connected to a battery (see Section 9.2.2 for additional information regarding the Voltage and Battery Type String). If the routine detects an issue, one (1) of the codes listed in Figure 5.4-1 below will be shown on the main display. Figure 5.4-1 also provides instructions for correcting each potential issue. www.douglasbattery.com 12 of 30 User’s Manual
