Use Table 3 to select fuse size (in Amps). The voltage rating should match or exceed the nominal
AC input voltage to the power controller.
Over-current protection devices must also be installed on the primary of the isolation
transformer and sized according to applicable local electrical codes.
Do NOT install fuses, circuit breakers or any type of switching device between the DC output of
the power controller and the CEDI module. Doing so might eventually cause damage to the
power controller.
Snubbers:
Snubbers should be installed for an extra layer of protection against very high energy spikes
whenever the power controller is fed with 660 Volts or at sites with poor electric power quality
indicated by swells, over-voltages, surges, etc.
Snubbers are most effective when installed on the secondary of the transformer, between any
switching devices and the power controller. Schematics showing their ideal location are found in
Appendix C.
Ionpure® offers voltage snubber circuits, model numbers IP-SNUBCIRC-1PH and IP-SNUBCIRC-
3PH. The 3-phase version is only suitable for installation on the primary side of the isolation
transformer, while the single phase version can be installed on the transformer secondary. Refer to
the Voltage Snubber instruction manual (available at
) for details.
Enclosure:
Sizing: the width and height will depend on size and number of components inside the
enclosure. There should be at least two inches of clearance from the top of the power controller
to the door of the enclosure to allow proper air flow.
Cooling: the G2 power controller will dissipate a maximum of 260 watts in the form of heat. The
panel enclosure should have proper ventilation to ensure the power controllers operate at a
temperature no higher than 50 °C.
Contactor (optional):
A contactor can be installed downstream of the over-current protection devices (fuses or breakers)
to completely remove AC power to the G2 power controller. This might be desired for emergency
stop and/or manual override implementation.
Power to the CEDI module must be enabled/disabled using the Remote ON/OFF input of the power
controller, as described in section 2.5.3.
