Connecting the Power System to the AC Supply

Data Power Solutions can be connected to single-phase (L-N), two-phase (L-L), three-phase (L-N) and three-phase (L-L) AC power distribution systems.

Fused AC power sockets (one per rectifier) are available for connecting the power system to the AC supply. These fused AC power sockets are labeled K1 to K3 on APS3 and K1 to K6 on APS6 power systems. AC power socket K1 powers Rectifier 1, etc. (See Chapter 1 for location of Rectifier 1.)

No AC power cords are supplied with the power systems.

AC Supply Requirements

•AC Power Cords – The AC power cords (supplying the power system) must be suitably rated for the environment and AC distribution system. In addition, these AC power cords must be approved and installed to comply with local wiring regulations. (See Appendix C for maximum AC input current specifications.)

The earth conductor of each AC power cord must have a minimum cross sectional area of 1 mm2 (0.00155 in2).

The maximum length of each AC power cord should not exceed 3m (10 feet), unless local wiring regulations permit otherwise.

•Desktop Versions – If APS3-06X 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 – Data Power Solutions 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 power source and the power system according to the AC Supply Requirements above, but do NOT switch on the AC supply at this stage.
