AC Power
WARNING
– DANGER! Users should exercise extreme care when working with electricity. Additional care
should be used when working with electricity outdoors in inclement weather. When working
outdoors or near water, always connect the system into a ground-fault interrupting circuit.
AC Power Distribution Unit
By connecting the AC Power Distribution Unit to Stadium Power (or equivalent AC power source), the Power Distribution Unit
provides AC power to the Inverter/Battery Bank, Power Bay fans, and the 5-bay RP battery charger(s) contained within the
Sideline Cart.
CAUTION:
The cart’s AC power distribution unit’s switch (located on the front rack, behind the acrylic
door) must be in the RESET (ON) position for the cart battery bank to charge. CoachComm
recommends leaving this switch in the ON position at all times.
Inverter/Charger and Battery Bank
All AC power is distributed to the Sideline Cart through the AC inverter and battery bank. These devices back up the system
in the event of a power failure. The inverter and batteries will keep the system operating for approximately 4 (or more)
hours before running out of battery life.
Note:
When operating in battery backup, the WIM cannot engage the DPT since both ends of the system
must have power to operate in test mode.
During the 4+ hour backup power window, restore AC power from the stadium or prepare for wired-only operation. (AC
power must be connected to the press box unit for the wired portion of the system to function with the absence of AC
power on the sidelines.) In the event of a complete failure of AC on the sidelines (both from the stadium and depletion of the
battery bank) the wireless portion of the system and the ringdowns will not function. The wired portion of the system will
function with AC power on either or both ends, but not reliably.
Battery Bank Breaker
Plug in your cart to charge for a minimum of 8 hours after every use.
This prevents the cart battery bank from being
too low to power on or to charge with the onboard system. When the cart is not in use, you may store it in one of two ways:
1) with AC power connected (therefore maintaining battery bank charge using Float Charge Mode) or 2) with the battery
bank breaker turned off.
If the cart has been stored with the breaker (located in the belly compartment) in the ON position without connection to
AC power during that time, the batteries may be too low to power your system. Contact CoachComm Customer Support at
1.800.749.2761 for assistance if this occurs with your cart.
Turn breaker OFF when traveling.
The battery bank breaker protects the cart’s battery circuit from damage resulting from
an overload or short. The breaker should be turned OFF when transporting the cart to away games. Allow enough space to
access the belly compartment when storing or transporting so you can turn on the breaker and activate the drive system to
unload the cart.
