Warnings
This section contains important warnings relating to:
• AC Inputs
• Equipment Classification
• Batteries (if applicable)
• DC Outputs
• Rectifiers
• Location and Environment
• Servicing
• EMC Compliance
AC Inputs
• Desktop Versions:
Pluggable Type A: Except for 120V input, 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.
• 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.
• The AC power cords (supplying the power system) must be suitably rated for the
environment and AC power distribution system. In addition, these AC power cords
must be approved and installed to comply with local wiring regulations.
• The earth conductor of each AC power cord must have a minimum cross sectional
area of 1 mm
2
(0.00155 in
2
).
• The maximum length of each AC power cord should not exceed 3m (10 feet), unless
local wiring regulations permit otherwise.
• Ensure that the AC supply is disconnected from those fused AC power sockets before
checking or replacing their respective fuses.
• Each socket, K1 to K3 (APS3), and K1 to K6 (APS6), contain two fuses, FS1 and FS2.
CAUTION: DOUBLE-POLE / NEUTRAL FUSING
• Use only 15 A, 250 VAC, 6.3 x 32 mm, fast-acting fuses of the same type (Bussman
ABC-15 or Littelfuse 314-015 Type 3AB) for continued protection against risk of fire.
Equipment Classification
• 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.
• APS3-06X (desktop versions) are classed as “Pluggable equipment Type A” and
intended for use as “Desktop units”. All other units, APS3-05X and APS6-05X are
“Pluggable Equipment Type B” or for “Permanently connection” in host equipment.
