) authorized
Electrical Hazard:
Warning: Before performing any service, properly de-energize and remove access to
the equipment (Lockout). Physically label the equipment as intentionally out of service
(Tagout).
Do not wear jewelry when working near energized components.
InRow SC Operation2
Commissioning
Warning: APC authorized personnel must perform the following procedures.
Electrical Hazard: Perform Lockout/Tagout procedures on the cooling unit before
servicing the cooling unit. Failure to remove power before servicing this equipment could
result in serious injury or death.
After installation is complete, verify that all components are working properly and that the cooling unit
is ready to begin operation.
Inspection Checklists
Initial inspection checklist
The initial inspection ensures that the cooling unit has been properly installed, the location of the cooling
unit has been properly prepared, and the cooling unit is free of damage.
Warning: The cooling unit operates under pressure. Take proper safety precautions
when connecting gauges or servicing piping.
Warning: Do not operate the cooling unit with any cover, guard, door, or panel removed
unless the instructions indicate otherwise. Then, proceed with extreme caution.
Warning: Do not run service utilities in front of the fan outlets.
unit is required for service access. To roll the cooling unit out of the row, there must be a
minimum of 1200 mm (48 in) of clear floor space in front of or behind the cooling unit.
Out-of-row service requires 760 mm (30 in) of side clearance in addition to the front and rear
clearance.
Ensure that:
The installation procedure is complete according to the installation manual.
The walls, floor, and ceiling of the room where the cooling unit is located are sealed with a vapor barrier.
There is no evidence of damage to the cooling unit.
The cooling unit is level and joined to the adjacent racks or secured to the floor.
The clearance around the cooling unit is in accordance with local and national codes and regulations as
well as the installation manual.
Caution: The vapor barrier minimizes moisture infiltration. Without a vapor barrier, it will
be difficult to maintain the humidity in the room.
Caution: Do not introduce unconditioned outside air into the space.
Note: A minimum of 900 mm (36 in) of clear floor space in front of and behind the cooling
3InRow SC Operation
Electrical inspection checklist
The electrical inspection verifies that all electrical connections are secure and correct and that the
cooling unit is properly grounded.
Electrical Hazard: All electrical wiring must comply with local and national codes and
regulations.
Electrical Hazard: The equipment must be grounded (do not use a water-pipe ground).
Ensure that the:
Incoming voltages match the phase and voltage listed on the nameplate.
Electrical wiring complies with local and national codes and regulations.
Cooling unit is properly grounded.
Electrical connections are tight, including contactors, terminal blocks, controllers, switches, relays,
auxiliary devices, and field connections.
Mechanical inspection checklist
The mechanical inspection verifies that all mechanical components and connections are secure and tight
and ready for start-up and system charging. The inspection ensures that field piping is properly installed
to promote oil return to the compressor.
Caution: Improperly installed piping may result in improper operation and possible damage
to the cooling unit or surrounding equipment.
Ensure that the:
Fans are turning freely and that the blades are not distorted or bent.
Condensate drain line is at least the size of the drain connection.
Mechanical connections are tight, including compressor and receiver connections.
Ceiling tile adapter is secured to the building structure with properly-sized safety wire.
Covers and guards are in place.
InRow SC Operation4
User interface inspection checklist
The user interface inspection verifies that the sensors and internal communications links of the cooling
unit are installed properly.
Ensure that:
An A-Link bus is connected to each cooling unit in the group and a terminator is plugged into all unused
A-Link connectors.
The input contacts and output relays are connected correctly.
The building management system (if used) is connected correctly.
The temperature sensor is properly routed and mounted on the front (entering air side) of the enclosure
immediately to the left or right of the equipment (if InRow or RACS operating mode will be selected).
The network port is connected correctly and an IP address has been assigned to the equipment.
Start-up inspection checklist
The start-up inspection ensures that the cooling unit is operating properly after the initial start-up. This
inspection verifies that all modes of operation are working correctly and that the cooling unit is ready for
normal operation.
While the cooling unit is operating, ensure that the:
Cooling unit is free from malfunctions, unusual vibrations, or other irregularities in each mode of
operation.
Cool cycles engage.
Cooling configuration matches the application of the cooling unit.
Air filters are clean and free of debris. Replace air filters with APC part number 875-2013.
Clogged filter alarm is operating properly:
Cover 1/3 of the filter area and monitor alarm performance.
Compressor suction and discharge pressures are recorded.
Final inspection checklist
The final inspection verifies that the system is clean and the start-up form has been sent to APC.
Ensure that:
The interior and exterior of the cooling unit is clean and free from debris.
Packaging materials have been disposed of properly.
The Start-up form was completed and sent to APC.
