Feature Description
AC Input Circuit Breaker This circuit breaker is an On/Off switch for the utility/line power into the
unit. It must be switched On for proper operation.
Battery breaker This circuit breaker provides over-current protection and is used as an
On/Off switch for the battery power. It must be switched On for proper
operation.
Battery connector The battery connector connects the external batteries to the unit.
Battery temperature
sensor connector
The battery charging voltage is temperature dependent when
compensation is not set to 0 mV/°C/cell. A battery temperature sensor
connects to the unit so the microprocessor can adjust the charging
voltage for optimum charging. Refer to UPS Maintenance > Battery .
The sensor MUST be attached to the unit for normal operation. If the
sensor is not attached, a “Temperature Probe Unplugged” alarm
appears on the LCD.
Battery voltage test points These test points accept 2mm diameter test probe tips. The battery
circuit breaker must be on to measure the battery voltage.
NOTE
: The battery voltage test points are not to be used as a power port.
CAN connection CAN connector connects additional Input/Output ADIO modules to the
system.
Ethernet (1 & 2) Ethernet ports 1 and 2 connect the unit system to the network.The
default IP address for Ethernet Port 1 is 192.168.0.90 and the Ethernet
Port 2 is Auto.
Fan assembly This microprocessor-controlled fan turns on at a preset temperature to
lower the unit’s internal temperature. It must not be blocked. An Alarm
is generated if the fan fails; a failed fan can be replaced in the field.
Input Terminal Block The unit’s AC line power input.
LCD control panel The LCD control panel is used to monitor and control the unit.
