4.11 SG-PSU5 250W and 600W power supply
Depending on system load requirements the SG-System 5 may be equipped with one of two power supply modules. The SG-PSU5-600W is a 600W
power supply. The SG-PSU5-250W is a 250W power supply. These power supplies are able to operate from 100-240Vdc 50/60Hz. A power cord
with a IEC connector is required.
NOTE: For UL/ULC installations use only 120VAC/60Hz to power the SG-System 5. For UL installations use a UL listed UPS Power Sup-
ply for protective signaling systems and/or listed burglar alarm power supply, as applicable.
The SG-PSU5 red tray latch prevents the installation or removal of the power supply when the IEC connector is in place. The latch must be in the open
position for the removal or insertion of the SG-PSU5. Any attempt to install or remove the SG-PSU5 when the latch is in the closed position could
cause equipment failure or damage.
