Chapter 1 Safety
1.1 Safety Information
For the continuing safety of the operators of this equipment, and the protection of the
equipment itself, the operator should take note of the Warnings, Cautions and Notes
throughout this handbook and, where visible, on the product itself.
The following safety symbo ls may be u sed throughout the h andbook and on the
equipment itself.
1.2 General Warnings
Shock Warning
Given when there is a risk of injury from electrical shock.
Warning
Given when there is a risk of injury to users.
Caution
Given when there is a risk of damage to the product.
Note
Clarification of an instruction or additional information.
Warnings
If this equipment is used in a manner not specified by the manufacturer, the
protection provided by the equipment may be impaired. In particular,
excessive moisture may impair operation.
This product generates, uses and outputs high voltages from the SMC
connector (HV Output) that are hazardous and can cause serious injury. In any
installation that uses the KPZ101 it is the user’s responsibility to ensure
adequate insulation and precuations are taken to avoid shock risk. Cables for
HV Out must be rated for 250 V RMS.
Spillage of fluid, such as sample solutions, should be avoided. If spillage does
occur, clean up immediately using absorbant tissue. Do not allow spilled fluid
to enter the internal mechanism.
