Safety and Grounding:
Read the following information before installing or operating your DIGITUS
Automatic Transfer Switch:
•This ATS is intended for indoor use only.
•This ATS must not be operated one behind the other!
•Operation only in dry and closed rooms.
•This ATS may not be operated covered. Always ensure free accessibility.
•The maximum power stated on the rating plate must not be exceeded.
•Plug this ATS into a three-wire, grounded power outlet only. The power outlet
must be connected to appropriate branch circuit/ mains protection (fuse or
circuit breaker). Connection to any other type of power outlet may result in a
shock hazard.
•Use only the supplied brackets of mounting.
•Check that the power cord, plug, and socket are in good condition.
•Voltage free only when the power plug is unplugged.
•Disconnect the PUD from the power outlet before you install or connect
equipment to reduce the risk of electric shock when you cannot verify
grounding. Reconnect the ATS to the power outlet only after you make all
connections.
•Operation under unfavorable environmental conditions must be avoided.
(Humidity over 80% relative, wet, ambient temperatures above 50 ° C, solvents,
flammable gases, dust, vapors).
•If external damage to this ATS is detected, do not operate this ATS. Take this ATS
immediately out of service if external damage is detected.
•Do not pour liquids over the power strip. There is a high risk of fire or life-
threatening electric shock.
•When opening the power strip, live parts can be exposed. There is a risk of
electric shock. The power strip may only be opened by a specialist.
