Battery Maintenance Guidelines The battery maintenance instructions listed below are for reference only. Battery manufacturer’s instructions for transportation, installation, storage or maintenance take precedence over these instructions. • To prevent damage, inspect batteries every 3 months for: Signs of battery cracking, leaking or swelling. The battery should be replaced immediately by authorized personnel using a battery of the identical type and rating. -
Page 9: Grounding Connection
Grounding Connection In order to provide a ready, reliable source of backup power it is necessary to establish a grounding system that not only provides for the safety of the service personnel responsible for its operation and maintenance, but also facilitates the proper operation and protection of the equipment within the network. Such a grounding system will provide protection with respect to operator safety, system communication, and equipment protection. -

Installation, continued Battery and Remote Temperature Sensor Probe Installation The diagram below is for illustrative purposes only. Exact battery orientation may vary. Do not connect the batteries to the Flexnet 300 unit at this time. The RTS must be taped to the side of a center battery as shown below. -
Page 13: Output Connections
Installation, continued Output Connector The output connection is located on the front panel of the unit. Plug the 48VDC fiber node into this connector. Status Monitoring Connector The Status Monitoring connector is located on the front panel of the unit. Associating with this connector, an opto-coupler transistor array is connected between the output alarm pins (Batt Low, Batt Miss, Repl Batt and AC Fail) and the ground pin (Tel Comm) as shown. - Page 14 In order to correctly receive the alarm signals, it is recommended to put a pull-up resistor between the receive circuit’s logic power (3.3V or 5V) and each alarm line at the alarm signal monitor side, as shown below. The resistance may vary per current requirement of the receive circuit.

Page 15: Status Leds
Installation, continued Status LEDs The status LEDs are located on the front panel of the unit. Normal operation is indicated by the green LED ON, and the red LED OFF. LED status indication also has a time delay when reporting failures. The time delay is similar to that illustrated in Section 1.5. -
Page 16: Output Distribution Board (Optional)
Installation, continued Output Distribution Board (optional) The Output Distribution Board (Alpha P/N 745-577-20) splits the ELPM300-48D’s 300W output into two 150W isolated outputs. Each output has its independent protection circuit. One output overload or short circuit will only trigger its own protection and not affect the other circuit’s normal operation. -
