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.
(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 mm

(0.00155 in

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