4.4.2 Positioning of the PDU
Your PDU has been designed to perform at optimum efficiency when the following positioning concerns are taken
into consideration:
1.
The system is designed to properly cool by using natural convection. Positioning the unit onto the
raised floor ensures optimum placement practices.
a.
Some applications may require fans to assist with cooling. Refer to as ordered documents
2.
The system is enclosed in one of the industry's most substantial cabinets and contains electrical
apparatus such as molded case circuit breakers, transformers, and distribution panelboards.
Consequently, floor loading should be addressed to verify the PDU system does not exceed your raised
floor load specifications.
Refer to section 4.2.1 for weight and dimensional specifications of your ABB product.
3.
If additional raised floor supports are required, contact your raised flooring supplier or ABB for either
floor jacks or full frame floor stand specifications.
4.4.3 Access
The system is designed to allow the customer to use every available square foot of computer room space for
operating your computers versus your power conditioning equipment. TruFit PDU products typically require
forty-two inches (42") of FRONT ACCESS for service area. Please refer to supplied outline drawing for exact
service and operational access requirements.
The forty-two inches (42") of front access allows the unit to be fully serviced while also complying with most local
electrical codes for access to circuit breaker distribution equipment. Please refer to applicable local electrical
codes, as these will take precedence.
4.5 Handling and moving the equipment
−
The units are bolted to shipping pallets to allow handling by forklift or pallet jack.
−
Move the equipment in its original packing to the place of installation before unpacking.
−
Set the packaged units in a level area with sufficient room for removal from the shipping pallet. Remove
external shipping material; locate and remove the bolts at the base of the unit (used to secure unit to the
pallet). Using a forklift, raise the unit off the pallet and onto the floor. If the unit includes a sidecar, a
forklift is permitted if the unit is lifted at the center of gravity.
−
Internally inspect the unit per inspection items listed in section 4.6.2.
Consideration should be given as to how to protect the raised floor while PDU is moved across.
−
Make sure all ventilation openings are clear of obstructions.
−
Risk of unit damage.
−
Exercise extreme care to avoid equipment damage or injury to personnel.
−
Do not exceed a ten (10) degree tilt by forklift or incline ramp.
−
Note: The unit's weight and center of gravity before handling the cabinet.
−
The PDU is not designed to rest on its ends or sides, regardless of the
packaging.
