Electrical Safety

• Please follow any applicable safety regulations and laws when performing electrical work. All electrical

work should be carried out by a qualified individual.

• Before beginning any work with the switch carefully check for any potential dangers in the working area,

eg. a damp or wet floor, an ungrounded power supply, or an unreliable grounding of the power supply.

• Locate the emergency power off switch in the room before installing or working on the switch.

• If an electrical accident occurs, cut off the power supply to the Switch first.

• Avoid carrying out maintenance on the equipment alone when the Switch is powered on.

• Before shutting down the power supply, check that it is safe to do so.

• Do not place the Switch in a damp/wet location. Ensure that no liquid enters the chassis.

• Ensure that all grounding conductors are connected both before, and after the line and neutral (AC)

conductors are connected.

• Disconnect all power supply cords before servicing.

• Connect the power cable to a circuit breaker rated not greater than 20A.

• When installing multiple power supplies, connect each power supply to a different, independent over-

current protection device, such as a circuit breaker. If a single power source fails, it will affect only the

power supply to which it is connected.
