Installation; Location; Dc Wiring - Ultimate Power UP1200PCUL User Manual

The Operation of DC fan at the DC terminal side is controlled in the following logic:
Condition
HEAT SINK
TEMPERATURE
CHARGER CURRENT
LOAD Percentage
(INV MODE)
Allow at least 30CM of clearance around the inverter for air flow. Make sure that the air can circulate freely around the
unit. Fan noise level <60db at a distance of 1m

4 Installation

4.1 Location

Follow all the local regulations to install the inverter.
Please install the equipment in a location of Dry, Clean, Cool with good ventilation.
Working temperature: ‐20℃ to 50℃ (-4℉ 122℉)
Storage temperature: ‐40℃ to 70℃ (-40℉ 158℉)
Relative Humidity: 0%to 95%，non-condensing
Cooling: Forced air

4.2 DC Wiring

It is suggested the battery bank be kept as close as possible to the inverter. The following table is a suggested wiring
option for 1 meter (3ft.) DC cable.
Rate Current
200Amp Max
300Amp Max
400Amp Max
Please find the following minimum wire size. In case of DC cable longer than 1m (3ft.) please increase the cross
section of cable to reduce the loss.
Reducing RF interference
To reduce the effect of radiated interference, twist the DC cables. To further reduce RF interference, shield the cables
with sheathing /copper foil / braiding.
Taping battery cables together to reduce inductance
Do not keep the battery cables far apart. In case it is not convenient to twist the cables, keep them taped together to
reduce their inductance. Reduced inductance of the battery cables helps to reduce induced voltages. This reduces
ripple in the battery cables and improves performance and efficiency.
