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.
