Safety Signs Meaning

DangerIndicates an imminently hazardous situation, which if not avoided, will

result in death or serious injury. This signal word should be limited to only

extreme situations.

WarningIndicates a potentially hazardous situation, which if not avoided, could

result in death or serious injury.

CautionIndicates a potentially hazardous situation, which if not avoided, could

result in minor or moderate injury. It may also be used to alert against

ElectrostaticThe device may be sensitive to static electricity.

Read the safety instructions before any operation of the equipment. The safety precautionsmentioned in this manual only serve as a supplement to the local safety codes.

Only trained professionals are allowed to install, operate and maintain the equipment. ZTEbears no liability to the consequences incurred by violation of the general safety operationrequirements, or violation of the safety standards for designing, manufacturing and usingthe equipment.

Take the following precautions when installing and operating the equipment.

High VoltageDirect contact or indirect contact with high voltage and mains through damp object willendanger the operator’s life.

l Observe the local safety codes during the equipment installation. The installationpersonnel must be qualified for high voltage and AC power operations.

l Never wear any conductive object, such as watch, bracelet or ring during the operationon the equipment.

l Prevent any moisture from entering the equipment during operations.

No Object With Harmful EffectsProtect the equipment against ingress of objects with harmful effects, such as conductiveobject and water. Otherwise, short circuit may occur and damage the equipment!

I


High Leakage Current

Earth connection is essential before connecting supply.

DC Short Circuit

Avoid short circuit during operation. ZXDU68 T451 system is a power supply product ofconstant DC voltage.

Connecting or Disconnecting Power Cable

Power cable operation with power ON will cause fatal danger to operation personnel anddamage to the equipment.

l Set all the breakers and switches to Off prior to connecting or disconnecting a powercable.

Setting all the breakers and switches to Off will cause power supply interruption to theloads connected. Do not shut down the system without permission. Or, switch theloads to another power supply system.

l Prior to connecting a cable, make sure that the cable and its label are in accordancewith the requirement.

Tools Safety

When operating high-voltage equipment, tools safety must be considered. Use InsulatedTools.

Electrostatic Damage

Electrostatic discharges generated by human body may damage components. Use wriststraps when handling the equipment. Insulate the uncovered metals to prevent shortcircuit.

Operation on Battery

l Before performing any operation on battery, read the safety precautions in the batterymanual.

l Connect the battery cables according to the instructions. Avoid short circuit andelectrolyte leakage.
