PLZ-U Safety Precautions III

Installation

• When installing products be sure to observe 2.2, “Precautions Concerning Instal-

lation 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

• Use extra precautions such as using more people when relocating into or out of

present locations including inclines or steps. Also handle carefully when relocat-

ing tall products as they can fall over easily.

• Be sure the operation manual be included when the product is relocated.

Operation

• Check that the AC input voltage setting and the fuse rating are satisﬁed and that

there is no abnormality on the surface of the power cord. Be sure to unplug the

power cord or stop applying power before checking.

• If any abnormality or failure is detected in the products, stop using it immediately.

Unplug the power cord or disconnect the power cord from the switchboard. Be

careful not to allow the product to be used before it is completely repaired.

• For output wiring or load cables, use connection cables with larger current capac-

ity.

• Do not disassemble or modify the product. If it must be modiﬁed, contact Kikusui

distributor/agent.

Maintenance and checking

• To avoid electrical shock, be absolutely sure to unplug the power cord or stop

applying power before performing maintenance or checking.

• Do not remove the cover when performing maintenance or checking.

• To maintain performance and safe operation of the product, it is recommended

that periodic maintenance, checking, cleaning, and calibration be performed.

1.1 About This Manual

This operation manual covers the following PLZ-U Series Electronic Load Units.

Product version covered

This operation manual covers products with frame ROM version 1.0X and load unit

ROM version 2.0X.

When contacting us about the product, please provide us the following information.

Model

ROM version

Manufacturing number (indicated at the lower section on the rear panel on the

frame and on the top panel on the load unit)

For the procedure of conﬁrming the ROM version, see section 2.6, “Power Up.”

1.2 Product Overview

The PLZ-U Series Electronic Load Unit is a compact, high-performance, multi-

channel electronic load unit that has three operation modes: constant current, con-

stant resistance, and constant voltage.

The PLZ-U consists of a frame and load units. Load units are inserted into the frame

(control section) for operation. The PLZ-30F and PLZ-50F Frames can accommo-

date up to 3 channels and 5 channels of load units, respectively.

The current capacity or power capacity can be increased through a parallel opera-

tion of load units. The load units can be combined to produce a power capacity from

75 W to 750 W (when ﬁve PLZ150Us are installed into the PLZ-50F).

In addition to high-speed response and highly precise preset resolution, various

functions are provided including the soft start function, variable slew rates, switch-

ing function, ABC preset memories, four setup memories, and sequence function.

Because the PLZ-U comes standard with GPIB and RS-232C communication func-

tions, it can easily be incorporated into various test and inspection systems. The

communication functions are useful for testing batteries, DC/DC converters,

switching power supplies, and multi-output power supplies.
