Eaton Electrical APR48 Connecting the Battery Temperature Sensor Cable, AC Supply Requirements

Data Power Solutions Quick Start Guide

Installing the Battery Temperature Sensor (if batteries are fitted)

This section applies to APS3-059, APS3-061 and APS6-059 dc power systems only.

Each APS3-059, APS3-061 and APS6-059 dc power system is supplied with a battery temperature sensor and standard 2m (6.5 feet) long cable (factory-fitted to the sensor). Longer cables are available from your local Eaton dc product representative or you can make up your own. We strongly recommend limiting the maximum cable length of the battery temperature sensor to 20m (65 feet) because of noise considerations.

Connecting the Battery Temperature Sensor Cable

There are two screw-clamp terminal blocks at the rear of APS3-059, APS3-061 and APS6 059 dc power systems for terminating the battery temperature sensor cable, the two terminal blocks are labeled TEMP SENSOR (+) and TEMP SENSOR (-).

•Terminate the Black / White wire at TEMP SENSOR (+) and the Black wire at TEMP SENSOR (-).

•To ensure reliable connections at the battery temperature sensor terminal blocks, torque the clamp screws 0.4 – 0.6Nm (3.5 – 5.3 lb-in).

•Use cable-ties (not supplied) and the provided cable-tie holes on the cable support bracket to tie down the battery temperature sensor cable.

On APS3-061 dc power systems, there is a hole on the battery cable clamp bracket, to tie down the battery temperature sensor cable.

Mounting the Battery Temperature Sensor

The battery temperature sensor is designed to measure the average ambient temperature around the batteries. It is important to mount the battery temperature sensor at a location that truly reflects the average ambient temperature of the batteries. Attaching the battery temperature sensor to the battery stand (above the middle batteries) may provide the most reliable temperature reading.

If possible, avoid:

•Placing the battery temperature sensor on top of battery cases.

•Attaching the battery temperature sensor to battery cables, terminals or interconnecting bars.

•Exposing the battery temperature sensor to direct sunlight and drafts from the air- conditioning system or open windows.

•Running the battery temperature sensor cable along power or earth cables.

Connecting the APS DC Power System to the AC Supply

APS dc power systems can be connected to single-phase (L-N), two-phase (L-L), three-phase (L-N) and three-phase (L-L) ac supply systems. Fused ac sockets (one per rectifier) are available for connecting the APS dc power system to the ac supply. These fused ac sockets are labeled K1 to K3 on APS3 and K1 to K6 on APS6 dc power systems. AC supply socket K1 powers Rectifier 1, etc. No ac power cords are supplied with APS dc power systems.

AC Supply Requirements

AC Power Cords – The ac power cords (supplying the APS dc 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 Specifications on page 28 for ac power cord specifications.) The maximum length of each ac power cord should not exceed 3m (10 feet), unless local wiring regulations permit otherwise.
