Power precautions
Ensure all power precautions are understood before installing the product.
Warning! If not avoided, the following could result in death or serious injury.
•
After the replacement of the power supply, hi-pot and ground/earth bond tests must be
performed. Only Christie qualified technicians who are familiar with the necessary precautions
can perform these tests.
•
Always connect the ground or earth first to reduce shock hazard.
•
Do not return the current through the ground or earth.
•
SHOCK HAZARD! The line cord has a maximum power carrying capability. For the maximum
number of tiles that may be connected per daisy chain when connecting to the power supply,
refer to the product specifications.
•
SHOCK HAZARD! A permanent single-phase connection must be installed between the LED tile
system and the AC power supply.
•
FIRE AND SHOCK HAZARD! Do not operate the system unless certified power connections,
providing the recommended voltage, are used.
•
HIGH TOUCH CURRENT HAZARD! To ensure reliable grounding, the power connection must be
made by using an industrial plug (pluggable type B), or be provided by a permanent connection.
•
A 13-20 A double pole mains circuit breaker, certified for the applicable local regulations, is
required. It must be part of the building installation and easily accessible.
•
Do not use a wall breaker greater than 20 A. This could result in severe damage to the tile
system in the event of a failure.
Caution! If not avoided, the following could result in minor or moderate injury.
•
SHOCK HAZARD! The line cord has a maximum power carrying capability. For the maximum
number of tiles that may be connected per daisy chain when connecting to the power supply,
refer to the product specifications.

Christie.

tripped over, or damaged by persons walking on or objects rolling over the cables.
•
