of the metal fasteners cannot be too tight.
Panel Cutout: W116mm*H90mm.
Note:
If the controller is installed directly in the genset shell or other fluctuated
equipment, the rubber pad must be installed.
Battery Voltage Input
ATS 420 controller is suitable for 8-36V DC battery voltage. Battery negative must be
reliably connected to the enclosure of the engine. The controller power supply B+

.
NOTE:
In case of floating charger connect charger output to battery positive and negative
directly, then, connect battery positive and negative poles to controller positive and
negative power supply.
Output and relay expansion
Note: All outputs of the controller are relay contacts. The maximum current
capacity is described in the "Parameters" in this manual. Please use it in the relay
current capacity. If an extended relay is needed, add a continuous current diode
(when the extended relay coil is DC) or a resistance-capacitance loop (when the
extended relay coil is AC) to both ends of the coil to prevent interference with the
controller or other equipment.
