INSTALLING THE AT30 

10 

1.6.  CHANGING THE TRANSFORMER TAPS 

 

IMPORTANT: The AT30 Battery Charger is designed for a single ac 
supply voltage. Note the ac voltage listing on the data nameplate 
and the tag attached to the front panel. If your particular ac supply 
voltage does not match your AT30 ac input requirements, you 
MUST change the ac input circuit breaker (and/or fuses) and the 
input surge suppressors. In addition, you must replace or rewire the 
transformer as described below. Failure to use the properly rated 
components may damage the charger. 

 

NOTE

: If your AT30 Battery Charger was ordered with 480 Vac - 

60Hz input or 220 Vac - 50/60 Hz input the transformer accepts 
only the listed voltage. 

Do not attempt to rewire these 

transformers.

 If a different ac input voltage is desired for the 

AT30, please contact your sales representative for ordering 
replacement parts. 

 

Before you connect ac power to the AT30, check the wiring of the main 
transformer (T1) to be sure it is connected for the desired ac input voltage. 
The main transformer was wired at the factory for the input voltage 
specified and listed on the data nameplate. 

If your AT30 was ordered with 208/240 Vac - 60Hz input and you need to 
change the factory-wired input voltage, do so by changing the jumpers on 
the main transformer (T1). If your AT30 was ordered with 380/416 Vac - 
50/60 Hz and you need to change the factory-wired input voltage, please 
consult the factory for special instructions. 

 

NOTE

: Before starting work, disconnect and lock out all external 

ac and dc power sources to the AT30. Note that just turning off 
the front panel ac and dc circuit breakers is not sufficient to 
eliminate live voltages inside the enclosure. Use a voltmeter at 
the ac terminals TB1-L1, TB1-L2 & TB1-L3 (ac), and the dc 
terminals TB1(+), TB1(-), the remote sense terminals (+/-), and 
any external wiring, to alarm relay contacts to verify that no 
voltage is present inside the enclosure.
