5.3Addition / Replacement Procedures

5.3.1Addition or Replacement of a Rectifier

! WARNING

PRECAUTIONS SHALL BE TAKEN TO AVOID SERVICE INTERRUPTIONS

WHEN INSTALLING A RECTIFIER, THE FLOAT AND EQUALIZE VOLTAGES MUST BE SET ACCORDING TO THE TYPE OF BATTERIES USED WITH THE SYSTEM. FAILURE TO SET THESE VOLTAGES PROPERLY MAY RESULT IN BATTERY UNDERCHARGING OR OVERCHARGING AND/OR BATTERY DAMAGE.

! WARNING

PROTECTING PERSONNEL AGAINST ELECTRICAL SHOCKS

INPUT VOLTAGES TO THE RECTIFIERS ARE AT A DANGEROUS LEVEL. ENSURE THAT THE CIRCUIT BREAKERS ARE LOCKED IN THE OFF POSITION AT THE AC SERVICE PANEL BEFORE ATTEMPTING TO WORK ON THE RECTIFIERS. DANGEROUS VOLTAGES MAY STILL BE PRESENT AT THE TERMINALS EVEN IF THE RECTIFIERS ARE OFF. USE A VOLTMETER TO VERIFY FOR THE PRESENCE OF SUCH VOLTAGES. DO NOT SWITCH CIRCUIT BREAKERS TO ON UNTIL INSTRUCTED TO DO SO IN THE APPROPRIATE PROCEDURE.

Add a rectifier as described in the following procedure for a Helios Rectifier 100/48 or as in the Adding a Helios Rectifier 200I/48 or 200E/48 procedure, whichever is applicable.
