Electrostatic Discharge; Laying Out Cables; Rectifier - Huawei TP48200A-HX09A2 Installation Manual

TP48200A-HX09A2 & TBC300A-TCA2
Installation Guide
If the "high electrical leakage" tag is present on the power terminal of the device, you must
ground the device before powering it on.

1.2.2 Electrostatic Discharge

The static electricity generated by human bodies may damage the electrostatic-sensitive
components on boards, for example, the large-scale integrated (LSI) circuits.
Human body movement, friction between human bodies and clothes, friction between shoes
and floors, or handling of plastic articles causes static electromagnetic fields on human bodies.
These static electromagnetic fields cannot be eliminated until the static is discharged.
To prevent electrostatic-sensitive components from being damaged by the static on human
bodies, you must wear a well-grounded electrostatic discharge (ESD) wrist strap when
touching the device or handling boards or application-specific integrated circuits (ASICs).

1.2.3 Laying Out Cables

When the temperature is very low, violent strike or vibration may damage the cable sheathing.
To ensure safety, comply with the following requirements:

Issue 01 (2013-10-25)
Cables can be laid or installed only when the temperature is higher than 0° C.
Before laying out cables which have been stored in a temperature lower than 0° C, move
the cables to an environment of the ambient temperature and store them at the ambient
temperature for at least 24 hours.
Handle cables with caution, especially at a low temperature. Do not drop the cables
directly from the vehicle.
When a rectifier is running, the temperature around the air exhaust vent at the rear is
high. Do not touch the vent or cover the vent with cables or other objects.
To prevent electric shocks, do not put your hands into rectifier slots.
