Eaton Electrical 10640205 Commissioning, AC Installation, Inserting the Access Power Rectifiers

Data Power Solutions Quick Start Guide

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.

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
