The 3916 is offered in only one chassis size with DC power, the 3916 DC
Standard (170-3916-901). This system includes a single integrated DC power
supply. The DC power supply operates at +/- 24 VDC or +/- 48 VDC, drawing
a maximum of 2 Amps.
For installations using 24 V input voltage, the recommended fuse value is a
minimum of 5 Amps. For systems using 48 V input voltage, the recommended
fuse value is a minimum of 2.5 Amps.
The DC power cord should be 14 AWG - 18 AWG wire. You will need to install
fork terminal spade lugs on the power cord to ensure a proper connection with
the terminal block of the power supply.
