Power On LED (Green) – indicates that the rectifier is

powered.

Non-Urgent Alarm LED (Yellow) – indicates non-critical

conditions, such as:

• Rectifier in power/current limit mode

(This normally happens for a short period of time when the batteries are recharging.)

• Rectifier operating in temperature turndown mode, because of high ambient temperature or low AC supply voltage

Urgent Alarm LED (Red) – indicates critical fault

conditions, that require urgent attention, such as:

• Rectifier failed

• Rectifier shut down

• AC supply failed (green LED off)

• Very high AC supply voltage

• DC overvoltage

General Description

Low Voltage Disconnect (if applicable)

APS3-059, APS3-061 and APS6-059 models are equipped with a Low Voltage Disconnect (LVD) module.

The LVD disconnects the batteries at the LVD disconnect voltage to prevent damage to the batteries due to excessive deep discharge. After the batteries are disconnected, they recover to their open-circuit voltage. The LVD reconnects the batteries automatically after the AC supply is restored. After the batteries are reconnected, the power system recharges the batteries and powers the loads.

Both the LVD disconnect and reconnect voltages are configurable. The default LVD disconnect voltage is set to 44 V and the reconnect voltage to 48 V. This hysteresis band ensures that the open-circuit recovery of the discharged batteries does not rise above the LVD reconnect voltage.

Important Notes for Rack Mounted Systems:

• If this DC power system is installed in a closed or multi-unit rack assembly ensure that

the ambient temperature is less than 40°C.

• Ensure that the air flow is not restricted.

• Ensure that the system’s weight is adequately and evenly supported.

• Take note of the maximum AC current stated on the nameplate. Ensure that the AC

supply is correctly rated.

• Ensure that reliable earthing is maintained. Carefully check earth continuity from the

branch circuit to the DC power system.

DC Installation Practices

Before you start connecting the DC load and battery cables (if applicable) to a power system, please read the following DC Installation Practices:

• On APS3-06X (desktop versions), run the DC load cables through the supplied nylon strain relief clamps at the rear. (See page 3clamps and using the incorrect torque setting for tightening their captive screws voids all safety approvals.

DC Installation Practices

5 for details.) Failure to fit the strain relief

• To easily distinguish between positive and negative load cables, we recommend using cables with different colors (as specified by local wiring regulations). The same applies to battery cables (if applicable).

• To reduce inductive coupling, separate DC load, battery and communications cabling from AC supply cables. If the cables have to cross, run them at right angles to the AC supply cables.

• In order to minimize parasitic cable inductance and reduce electromagnetic interference (EMI), all DC load cables should be routed in close proximity to one another, and large current loops should be avoided. The same applies to battery cables (if applicable).

Connecting the DC Load Cables

Eight DC outlets (labeled 1 to 8) are available for connecting your equipment power cables. Each DC outlet is protected by a corresponding 6 A or 25 A circuit breaker (accessible from the DC distribution at the front). The current rating of the corresponding circuit breaker determines the current rating of a DC outlet.

The DC outlets are floating to meet the isolation requirements for powering Power over Ethernet IEEE802.3af compatible devices. In non-Power over Ethernet applications the positive or negative output of the DC outlets can be referenced to earth, if required.
