WARNING:
• Batteries must be secured within the HPFF8 cabinet enclosure.
• Batteries must be lead acid and must comply with UL 2054. (See Section 4.3, Secondary Power.)
• Before applying power, inspect the Power Supply Board (Figure 1 in the Power Supply Installation
Guide) to ensure that SW1 is set to the Open position, to configure the unit for 24Vdc operation.
• Before applying power, inspect the Power Supply Board to ensure that jumper J1, AC Delay, is in
place.
• The Power Supply Board is not wired to chassis ground. When connecting the mains AC grounding
conductor, DO NOT connect to the G terminal on the Power Supply Board.
• Use a crimping wire nut of appropriate size to connect the mains AC grounding conductor to the
green with yellow stripe grounding conductor lead attached to the power supply cabinet backpan.
• Measure the output voltage at the [+BAT-] and [+DC-] terminals before connecting the batteries or
teleCARE IP system. Improper high voltage will damage the connected devices.
• Always de-energize the power supply unit prior to connecting the batteries and teleCARE IP
system.
• Refer to sections 4.4 and 4.5 in this manual before connecting and powering the teleCARE IP
system.
Connect the AC mains power (115Vac/60Hz) to the terminals marked [L, N] on the Power Supply
Board. Apply mains AC power. Measure and confirm 20Vdc to 26.4Vdcat the [+BAT-] and [+DC-]
terminals. Adjust the potentiometer next to SW1 to get 26.4Vdc at the [+BAT-] terminals. De-energize
the power supply, connect the batteries and teleCARE IP system, and re-energize the power supply.

4.1.2 Power Supply (Standard) Operation and Maintenance
The teleCARE IP Standard Power Supply should be tested at least once a year for proper operation.
Under normal load conditions, the DC output voltage should be checked for proper voltage level,
which is 24Vdc for the teleCARE IP system.
Under normal load conditions, check that the battery is fully charged. Check for the specified voltage
(24Vdc) at both the battery terminals and power supply board terminals marked [+BAT-] to ensure
there is no break in the battery connection wires.
