SIZE (AMPERES)
The above table (Table 3-1) is based on 75°C (167°F) rated conductors and 40°C (104°F) ambient temperatures. Refer to
National Electrical Code (2008) Tables 310-16 corrected to 40°C (104°F).
* For 115, 208, and 230-volt lines, use 250-volt disconnect switch.
For 440-480, 575-volt lines, use 600-volt disconnect switch.
* * Two conductors and ground conductor required for single phase.
Three conductors and ground conductor required for three phase.
Recommended minimum size of grounding conductors (based on National Electrical Code 2008 – Table 250-95).
Line Connections to Battery
Charger
Follow local code requirements if different than
instructions in this manual.
1. Turn charger OFF.
2. Be sure charger is connected correctly for avail-
able line voltage as instructed above.
3. On charger nameplate, note the AC input amperes
corresponding to the line voltage to which charger
is to be connected. Use that ampere value to
select the proper disconnect switch, fuse, and
power cable sizes from Table 3-1. A “WARNING”
label inside charger also lists fuse sizes for each
line voltage (circled fuse rating is required for
internal line voltage connections made at factory).
4. Route AC power input cable in through knockout
provided in side panel of charger cabinet.
Securely fasten cable wires to a power input
terminal inside charger. Refer to Grounding
section of this manual for proper connection of
grounding conductor. (Charger cabinet top or side
panel, or both, may have to be removed to provide
access to terminal block).
5. With disconnect switch (on AC input power line)
in “OPEN” or “OFF” position, connect power cable
coming from charger, to the switch. Install fuses in
switch.
Charging Cable Connectors
If connectors are already attached to charging cables,
make sure that they are attached so that positive
charger polarity will connect to positive battery
terminal.
