990-4618C-001 InRow Chilled Water Air Conditioners Technical Specifications 89
F. PRIMARY/SECONDARY POWER INPUT
1. Input Power Feeds
a. Primary/secondary power inputs should be a locking NEMA or IEC plug (ACRC301S,
ACRC500, and ACRC502) or hardwired connection (ACRC301H, ACRC500 series, and
ACRP500 series) suitable for the input power selected.
b. Each power input shall be capable of running the unit at 100% capacity in the event of a main
power failure.
G. MICROPROCESSOR CONTROLLER
1. Monitoring and Configuration:
a. The master display shall allow monitoring and configuration of the cooling unit through a
touch screen control. Functions include status reporting, set-up, and temperature set points.
Three LEDs report the operational status of the connected air conditioning unit. For ACRC500
& ACRP500, four LEDs report the operational status of the connected air conditioning unit.
2. Controls
a. The microprocessor controller shall allow the user to navigate between menus, select items,
and input alphanumeric information

a.The microprocessor controller shall activate a visible and audible alarm in the occurrence of the
following events:
1. Cooling Failure
2. Rack inlet high temperature
3. Rack inlet temperature sensor fault
4. Air filter clogged
5. Air filter run hours exceeded
6. Filter DP sensor failure
7. Supply air sensor fault
