DC Powering
Dual 48 Volt DC Powering Recommendations.
Observe the following guidelines for using the 48 Volt DC Power option.
(DC power cables are not supplied with the equipment.)
Only use wiring rated to safely handle 48 VDC/0.5A.
Use the provided Phoenix 4-position pluggable terminal block
(Phoenix MSTB 2.5/4 - STF - 5.08).
Each terminal connection of the Phoenix plug can only accept one 24 to 12 AWG stranded wire.
Do not exceed the rated capacity.
Use the shortest possible wire length.
Always use a continuous length of wire.
Do not splice wires to attain the needed length.
Use a larger wire size (within the recommended range of 24 AWG min to 12 AWG max) to
minimize voltage drops when wires must run a long distance.
Always use similar wire size for both the ‘+’ and the ‘-‘ sections.
Use wire trays for routing where possible.
Avoid running wires near high energy or AC wiring.
