Desktop Versions – If APS3-06X dc power systems are fitted with three rectifiers, then only
two ac power cords may be connected to one building branch circuit. The third ac power cord
must be connected to a separate building branch circuit. Failure to do so voids all safety
approvals.
Earthing – APS dc power systems are classified as “Class 1” equipment that must be
provided with an earth connected to the “Protective Earthing Conductor” in the building
wiring. The earth conductor of each ac power cord must be connected to the “Protective
Earthing Conductor” in the building wiring.
Earth Leakage Current – The maximum earth leakage current of each Access Power Rectifier
is 1.5 mA. Ensure that any upstream Residual Current Devices (RCDs) are appropriately
rated.
AC Installation
Install all ac cabling between the ac supply point and the APS dc power system according to
the ac supply requirements above, but do NOT switch on the ac supply at this stage.
Commissioning
Inserting the Access Power Rectifiers
Do NOT switch on the ac supply at this stage.
• Step 1 – Unpack the rectifiers and inspect them carefully for possible damage that may
have occurred in transit. Report any damage immediately, using a completed Equipment
Incident Report (located at the back of this guide) to supply all relevant details. Fax the
completed form to your local Eaton dc product representative. Keep the original
packaging. You will need this if any equipment needs to be returned to your nearest
authorized service agent for replacement or repair.
• Step 2 – Align the rectifier with the burst-out guides in the shelf.
• Step 3 – Push in the rectifier, to avoid injury to your hands, keep your fingers clear.
Slowly push in the rectifier, sliding it along the burst-out guides, until it plugs firmly into
the backplane connector. Tighten the rectifier retaining screw with a Pozidriv®
screwdriver.
Pre-Power-Up Check
Use the checklist below to complete initial checks before progressing further.
• All ac and dc cabling is installed, all cabling is neat and correctly insulated
• dc battery and load cabling has the correct polarity
• All panels are in place and all empty rectifier slots are covered with blanking panels
• The ac supply to the APS dc power system is switched OFF
• All circuit breakers at the front of the APS dc power system are switched OFF
• Batteries (if fitted) are isolated from the APS dc power system
