This unit has the capability to be mounted in any attitude but still requires M8 screws to be torqued to 200 lb-in.
8404-204, PISC model II, operates on a voltage source of eighteen to thirty-two volts of direct current. The power supply is the same as all of the other PISC models but operates on a different current capacity. The current capacity of this model is 15 A. Please advise that if a battery is being used as the operating power source, a battery-charging device or an alternator is required to maintain a steady supply voltage. When wiring the 8404-204 model take caution so as to avoid any potential hazards such as shock or potential overheating.
