The above table (Table 4-1) 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 available 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 4-1.
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.
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.

Warning: At all times, safety must be considered an important factor
in the installation, servicing and operation of the product and skilled,
qualified technical assistance should be utilized.
AC Supply Input Conditions:
Supply voltage should not exceed +/-10% of rated input voltage
value. Consistent power should be provided with fluctuations
not to exceed 1200VAC (850Vrms) for a duration longer than 25
Microseconds.
Mounting Pattern
This is an excerpt from the 199740 and 199752 outline drawings.
Please request if you need further mechanical information (utilize
a 3/8" or 9.5 mm drill bit) The fasteners are M8 -1.25 with a
maximum thread depth of 7.5mm. Please consider your rack or
shelf thickness as well as your washer thickness when selecting
an appropriate length
Note: remember to maintain 12" of free airspace between and in
front of each charger
Mounting pattern should be 4.53" (115 mm) square.

Do you have a question about the Deka PowerForce and is the answer not in the manual?
Questions and answers
battery charger not shutting off when charged and boils water out. Mod # 750H3-12C S/N 217CS582884
The Ametek Deka PowerForce battery charger may not be shutting off when charged and is boiling water out due to one or more of the following reasons:
1. Equalize Mode Active – The charger may be in Equalize Mode, which applies a prolonged charge to balance the battery cells. This mode extends charging time and increases voltage, which can cause excessive gassing and water loss.
2. No Gas Inhibit Not Active – If the No Gas Inhibit function is not enabled, the charger may continue charging at a higher rate, leading to excessive electrolyte boiling.
3. Improper Battery Maintenance – If the battery has been stored for 30 days or a large volume of water was added recently, the charger may be compensating, leading to overcharging.
4. Faulty Charger Settings – The charger may not be set up correctly, and its Auto Equalize by Cycle function may be triggering frequent equalization cycles, causing overcharging.
5. Defective Charger or Battery – A failure in the charger’s voltage regulation or a faulty battery with imbalanced cells could cause continuous charging beyond the required level.
To resolve this, check the charger settings, verify if Equalize Mode is needed, and ensure the battery is properly maintained. If the issue persists, inspect the charger and battery for faults.
