2 Remote Power-Off Device — Installation and Quick Start
Hardware Requirements
The Remote Power-Off Device requires the following:
• A Smart-UPS
®
or Matrix-UPS™.
• A switch (SELV or Class 2 circuit).
• A cable to connect the remote switch to the Remote
Power-Off Device.
Note
A Symmetra™ UPS has a built-in remote
power-off mechanism that turns off the
System Enable switch. For Symmetra UPS
models, use that mechanism, not this
external Remote Power-Off Device.
See “Remote switch: requirements and pin
assignment” on page 16.
See “Cable requirements” on page 22.
Warning
Incorrect installation can cause improper
functioning of the device or damage to
hardware. Substandard cables can produce
toxic fumes if a fire occurs.
