Energy Packs 25
Power Supply Requirements
When the Energy Pack is powered by an LPS Class 2, or a Limited Voltage/Current power
source, no additional over-current protection is required. Otherwise, power supply branch
circuit overcurrent protection of no more than 20 A with a readily accessible disconnect is
required, along with supplementary protection ranging from 4 to 7 amps on the output of
the power supply.
1.
Using the power cord, connect the power supply output to the input power terminal
block of the Energy Pack.
To insert the wires in the power terminal block connector, you may need to use the small
screwdriver to release the spring clamp on the terminal block.
Recommended wire stripping length is 7mm (0.28 in).

Insert the plug into the Input Power connector of the Energy Pack and securely
tighten the attaching screws.
Connecting the Energy Pack to the Controller
Note: Do not attach the Energy Pack to the Controller without first updating the Controller to the
minimum required firmware version, as specified in the Controller documentation.
With power to the system turned off, use the supplied cable or a user-supplied cable (1 m
maximum length) to connect the output of the Energy Pack (green connector) to the 24Vdc
input on the Controller (orange connector).
