XAP Series Busduct
Storage, Installation, and Maintenance
Preventative Measures
Care should be taken to protect the busduct from contaminants. For
in-door applications, inspect the busduct routing area looking for
possible moisture points from roof leaks, pipe leaks, dripping conden-
sation from pipes and HVAC equipment, and exhaust fans blowing dust
and debris onto the busduct. The busducts should be protected from
these hazards. All damaged equipment should be replaced. All
equipment subject to moisture intrusion should be replaced.
Busduct Inspection
1. Check the voltage of incoming terminals to make sure the busduct
system is de-energized;
2. Clean the busduct removing accumulated dust, dirt, and other
debris. Do not use water, liquid detergent, or chemicals to clean the
busduct;
3. Perform a visual inspection on the busduct looking for stress or
damage and moisture intrusion;
4. Inspect the joint unit bolts for tightness;
5. Check the insulation resistance and keep the record;
6. Perform an infra-red thermal scan on all electrical connections, joint
connections, and busduct enclosures while the busduct is fully
energized and operating under full load conditions. If readings
change with time, further inspection and corrections may be
required.
If damaged and/or over heating has been found, it is recommended the
following procedures be performed.
1. After the busduct has been de-energized, remove the joint covers
and visually inspect the joints looking for gaps in the contact surface
areas, cracks in the insulators, and contaminants or corrosion;
2. Clean, replace damaged parts, and re-torque (70±6 N•m) torque as
required;
3. Perform an insulation resistance test prior to re-energizing;
4. If moisture intrusion be found, remove and replace all affected
pieces.
Attentions for Installation
1. Surface of busduct terminals and joint units must be kept clean
during installation;
2. Busducts must be adjusted and kept in the same line before
fastening the bolts of joint units. Tolerance of assembly in horizon
and vertical direction are 5mm per 10m;
3. Socket protection cover shall not be opened during installation;
4. Equipment should be power off and grounded safely when
connecting the busducts to equipment.
Construction after Installation
1. Complete the decoration work;
2. Protective grid, rail and fire protection isolation device should be
completed;
3. Isolation for all living parts should be completed;
4. No construction impacts installed busducts should be carried out;
5. Equipment for construction should be removed and the place should
be cleaned.
Steps for Energizing
1. The entire busduct systems should be tested by Megger at 1000V
and insulation resistance should be higher than 0.5 M
Ω
;
2. Inspect the tightness of each joint unit to avoid any loosen bolt;
3. Make sure all tap-off units are in the open position;
4. Make sure the phase sequence of busducts is the same as incoming
system;
5. Busducts system should not be loaded before energizing;
6. Bustucts system should be energized without load for 24 hours
before carrying out a full load operation.
Maintenance Procedures
A preventative maintenance schedule should be established in order to
achieve the best possible service from your Eaton XAP busduct.
It is recommended that an annual maintenance check and necessary
procedures be conducted at a minimum. Busducts subjected to severe
operating conditions may require more frequent maintenance.
It is recommended that a permanent maintenance record be kept
recording the dates of service, work performed and any measured
data.
DANGER
HAZARD OF ELECTRICAL SHOCK OR BURN. TURN THE POWER TO THE
BUSDUCT OFF BEFORE INSTALLING, REMOVING, OR WORKING ON THIS
EQUIPMENT.
WARNING
ONLY THOSE TRAINED AND QUALIFIED IN RECOGNIZED SAFETY
PRACTICES SHOULD PERFORM MAINTENANCE ON THE BUSDUCT.
WARNING
FOR THE FOLLOWING PROCEDURES, THE BUSDUCT MUST BE SHUT OFF
AND DE-ENERGIZED.
WARNING
FAILURE TO FOLLOW SAFETY PROCEDURES MAY CAUSE PROPERTY
DAMAGE, SERIOUS PERSONAL INJURY AND DEATH.
