Smart-UPS On-Line 6000VA UPS

The APC Smart-UPS On-Line SURTD6000RMXLP3U is a 6000VA 4200W double-conversion UPS in a 3U rackmount form factor. It accepts 208V input and delivers selectable 120V or 208V output through six outlets including NEMA 5-20R, L14-30R and L6-30R types. This unit suits server rooms and network closets that require continuous sine-wave power with zero transfer time.

2.5-hour recharge sealed lead-acid battery

The replaceable RBC44 battery pack recharges in 2.50 hours after discharge. Audible alarms signal on-battery, low-battery and overload conditions. The UPS operates from an input range of 156 to 236V with an adjustable window down to 85V, and maintains output frequency at 50 or 60Hz within 0.1Hz. Surge energy rating is 480 Joules.

RJ-45 10/100 and SmartSlot management

Network management is provided through an RJ-45 10/100 Base-T port and an open SmartSlot for optional accessories. The input connection uses a NEMA L14-30P plug. Buyers needing 120V-only input or a tower form factor should consider other models.

Questions about this item

How do I connect the NEMA L14-30P input plug and which step do installers often miss?

Wire the L14-30P to a 208 V, 30 A circuit with neutral and ground; the step often missed is configuring the adjustable input range (85 – 136 V or 156 – 236 V) to match the actual supply before powering on.

Which battery kit replaces the internal cells and how long does a full recharge take?

Order RBC44 replacement cartridges; after a discharge the sealed lead-acid pack reaches full charge in 2.50 hours.

At what load does the 480 joule surge rating become the limiting factor during a prolonged event?

The 480 joule rating caps the total transient energy the unit can absorb; once that energy is exceeded the MOVs can no longer clamp, so the limit appears on the first large surge rather than from sustained watts.
