Access Power Solutions Installation and Operation Guide (APS6-600 Series for 3kW Rectifiers)

Warnings

This section contains important warnings. Read these warnings before installing or operating an
Eaton Access Power Solutions dc power system.

Electrical Safety
•
Access Power Solutions (APS6-600 Series) dc power systems must be mounted in an enclosed cabinet that
meets safety and fire enclosure requirements as specified in AS/NZS 60950.1 and EN 60950-1.
•
The dc power system may be powered from multiple ac sources. All ac sources must be isolated before
internally servicing the equipment.
•
The dc power system MCBs are not a disconnect device. The APS dc power system must be connected to a
suitable upstream ac supply disconnect device such as Miniature Circuit Breaker(s) (MCB) or fuses. This
device must isolate both the phase and neutral conductors in single-phase and three-phase connections,
unless the neutral conductor is clearly identified.
•
If the dc power system is to be installed in a location where the ambient temperature may rise above 50ºC
(122ºF), then 105°C rated cable rated cable must be used for all connections.
•
The dc power system is not compatible with IT (Impedance Terra) ac power distribution topologies. For
advice see Worldwide Support on page 103.
•
A registered electrician (or suitably qualified person) must check the integrity of the installed cabling,
BEFORE the dc power system is powered up.
•
Tasks must be performed in the sequence documented in this guide.

Location and Environment
•
An APS dc power system must be installed in a restricted access location.
•
For ease of access and to maintain optimum system cooling observe the clearances stated on page 24.
•
Dust build-up within the dc power system may cause premature failure. In dusty environments filter the
ventilation air entering the equipment room. Ensure regular cleaning of the air filters.
•
Do not allow water or any foreign object to enter the dc power system. Do not place objects containing
liquid on top of or near the unit.
•
Flooded cell and VRLA lead acid batteries can emit explosive gases and must be installed with adequate
ventilation. Refer to the battery manufacturer or supplier for advice on minimum ventilation levels.

Reverse Polarity
•
Always check that the battery cables have been terminated to the correct system polarity BEFORE
connecting the batteries or closing the battery disconnect device. Connecting batteries to the dc power
system with incorrect system polarity will damage the rectifiers and void all warranty claims.

Hazardous Energy Levels
•
Rectifiers and batteries contain hazardous energy levels. Only personnel trained and experienced in dc
power systems are to service/maintain this equipment.
•
Always use insulated tools.
•
Do not short-circuit the live and common bus bars or cables.
