8.2 DC power supply option
The range of DC sources is intended to include:
• Automotive—either mobile, such as trailer mounted, or static, such as a vehicle
battery or auxiliary output
• Conventional DCsupplies derived from AC mains, such as 12V or 24V supplies
powering PLCs
• Solar panels with any type of back-up battery within the input range
• Other renewable energy generators such as wind/hydro turbines with any type of
back up battery within the input range
Power cable: The pump is supplied fitted with a cable gland and approximately 2.0m
(6.6ft) of power cable and an IP31 splash proof blade fuse holder and 20A blade fuse. The
cable is not user-detachable and the entry gland at the front of the pump should not be
disassembled.
Notes
It is highly recommended that an isolating switch is provided between the power source
and the pump. The cable is fitted with M8 ring terminals to fit common isolators.
The 20A blade fuse is a safety device and should not be removed or the value changed.
The fuse holder is splashproof (IP31) but NOTwaterproof (IP66). Connection to the DC
source should be provided with appropriate IP protection.
Large start up currents may be required, especially at low voltages, see "Performance
data" on page127 for correct selection of power source.
We DO NOT recommend increasing the cable length when used in 12V systems due to
extra voltage loss in the cable. Increasing cable length will also invalidate the pumps EMC
compliance and require the user to perform their own system level EMC compliance check.
