IV Safety Precautions PLZ2004WB

Installation

• When installing products be sure to observe “2.2 Precautions Concerning Instal­lation Location” described in this manual.

•To avoid electrical shock, connect the protective ground terminal to electrical
ground (safety ground).

• When connecting the power cord to a switchboard, be sure work is performed by
a qualified and licensed electrician or is conducted under the direction of such a
person.

• When installing products with casters, be sure to lock the casters.

Relocation

•Turn off the power switch and then disconnect all cables when relocating the
product.

• Use two or more persons when relocating the product which weights more than
20 kg. The weight of the products can be found on the rear panel of the product

PLZ2004WB Safety Precautions V

Overvoltage Category

For the safe use of equipment, IEC60664 (Insulation coordination for equipment
within low-voltage systems) classifies circuits into four categories by an occurrence
level of transient voltage. When you connect equipment to a power line or connect a
measuring instrument to these places, make sure of the applied overvoltage cate­gory. This instrument is designed to operate from the overvoltage category II.

Overvoltage category I

Equipment of overvoltage category I is equipment for connection to circuits in
which measures are taken to limit transient overvoltages to an appropriately low
level.
Examples are protected electronic circuits.

Overvoltage category II

Equipment of overvoltage category II is energy-consuming equipment to be sup­plied from the fixed installation.
Examples of such equipment are appliances, portable tools and other household and
similar loads.
If such equipment is subjected to special requirements with regard to reliability and
availability, overvoltage category III applies.

Overvoltage category III

Equipment of overvoltage category III is equipment in fixed installations and for
cases where the reliability and the availability of the equipment is subject to special
requirements.
Examples of such equipment are switches in the fixed installation and equipment for
industrial use with permanent connection to the fixed installation.

Overvoltage category IV

Equipment of overvoltage IV is for use at the origin of the installation.
Example of such equipment are electricity meters and primary overcurrent protec­tion equipment.

About This Manual

This operation manual describes the PLZ2004WB Load Booster.

The PLZ2004WB is used in combination with the PLZ1004W Electronic Load.
This manual mainly covers the handling precautions of the PLZ2004WB and the
connection to the PLZ1004W. For the operating procedure as a electronic load, see
the PLZ1004W Operation Manual.

Product Overview

The PLZ2004WB Load Booster is used to increase the input current to the
PLZ1004W Electronic Load. One PLZ1004W is made the master unit, and load
boosters connected in parallel operate as slave units.

Features

Options

• Up to four load boosters can be connected in parallel with a PLZ1004W master

unit, configuring a electronic load that produces up to 9 kW and 1 800 A.

• The master unit displays the total current and total wattage. The units connected

in parallel can be used as a single electronic load.

• The connection of the control cables is easy. The control cable used to connect

between the master unit and the load booster and between each load booster is
one flat cable each.

• There is no power switch. The AC input power is turned ON/OFF by the master

unit.

Control flat cables

Control cable used to connect between the master unit and the load booster and
between load boosters. The following two types of cables are available.

Model Code Length Application

PC01-PLZ-4W 84540 300 mm Connect between load boosters

PC02-PLZ-4W 84550 550 mm Connect between the master unit and load booster

The two types of cables only differ in their length. The 550-mm PC02-PLZ-4W is
required to connect the master unit and the load booster.
