AFS670 | PRECAUTIONS AND SAFETY

WARNING Non-observance can lead to death or injury.

CAUTION

2019-04-30

With live power supplies short circuits with flash over might result. Make sure

that

→ The external powering is switched off before you connect the power leads

to the equipment.

→ The power cables provide sufficient insulation.

The equipment must be stable in its installed location. To achieve this secure

the equipment by fixing it into a rack that is itself made stable in use by fixing

it to the floor, wall or ceiling of a building interior, or by being part of a pur-

pose-built enclosure.

→ Make the rack stable before mounting the equipment into it.

→ Do not place heavy objects on or in the equipment. This can cause injury by

the heavy object becoming unstable.

→ Do not use the equipment on an unstable surface. The equipment may fall,

causing serious bodily injury and serious damage to the equipment.

→ Use one of the mounting methods defined in the Installation Instruction

when mounting the equipment.

Equipment that is not properly connected to earth poses a high risk that

could result in serious injury, and that could damage your equipment.

→ It is mandatory to connect the equipment to a suitable protective ground

e.g. the Common Bonding Network. Make sure the selected site provides

efficient earthing terminals, and that the equipment is properly connected

to earth. Only proper earthing of the equipment will protect you and your

equipment from lightning.

→ Connect the protective earth contact of the housing with the protective

earth of the power supply.

→ The negative (-) pole of the local power supply must be connected to earth.

The positive (+) pole of the local power supply must be protected with a

thermal-magnetic circuit breaker.

→ Instructions on correct earthing of the equipment are provided in the

installation instruction of the equipment.

Non-observance could result in minor or moderate injury.

There is a risk that higher-powered optical transmitters are located in adja-

cent equipment.

→ Do not look into the end of any optical fiber which might carry optical sig-

nals.

→ Do not look into an unterminated or broken optical fiber unless the optical

source has been turned off or the optical power is removed. Confirm the

removal of the power with an optical power meter over a period of at least

2 minutes. The 2-minute interval is required because most systems have

ALS (Automatic Laser Shutdown and auto re-start facility).

→ Fit all unconnected optical plugs and couplers with caps.
