CP CU1

CP CU1 - 1

The

CP CU1

’s outputs and the connected cables carry life-hazardous voltage or current.

►

Always obey the five safety rules and follow the detailed safety instructions below.

Note:

The safety instructions relevant to the

CPC 100

and its accessories (refer to page

Preface-1) also apply to the

CP CU1

. This section lists safety instructions that exclusively apply

to the

CP CU1

General

►

Before operating the

CP CU1

, read the CP CU1 Reference Manual carefully and observe

the safety rules and instructions therein.

►

Before handling the

CP CU1

CPC 100

in any way, connect them with a solid connection

of at least 6 mm² cross-section to ground. Ground the

CP CU1

as close as possible to the

CPC 100

►

Use the

CP GB1

grounding box to connect the

CP CU1

to overhead lines and power cables.

For detailed information, see the application-specific “Safety Instructions for Connecting

CP CU1

to Power Lines” in the CP CU1 Reference Manual.

►

When using the

CP GB1

, ground it near the place where the connection to the test object is

made. Make sure that the grounding stud is in good condition, clean and free of oxidation.

►

Make sure that all studs and cables of the

CP GB1

are screwed tight.

►

Make sure that the test object’s terminals to be connected to the

CP CU1

do not carry any

voltage potential. During a test, the only power source for a test object may be the

CP CU1

(powered by the

CPC 100

). The only exception are measurements on overhead lines as

described in “Applications” in the CP CU1 Reference Manual.

►

Use the

CP CU1

CP GB1

and their accessories only in a technically sound condition and

when its use is in accordance with the regulations. In particular, avoid disruptions that could
in turn affect safety.

Operating the Measurement Setup

►

When using the

CP GB1

, ground it near the place where the connection to the test object is

made. Make sure that the grounding stud is in good condition, clean and free of oxidation.

►

Life threatening voltages up to 600 V can appear on all

CP GB1

contacts and on all clamps

and cables connected to the

CP CU1

during the test. Keep safe distance from them.

►

Before handling the

CP CU1

CP GB1

in any way (even before setting the current range

switch), make sure that the device under test (e.g. overhead lines or power cables) are well
grounded (e.g. by closing the grounding switch) near the measurement setup.

►

Ensure that the short-circuit bar is always plugged in the

CP CU1

I AC

output whenever the

output is not connected to the

I AC

input of the

CPC 100

►

Connect the

CP CU1

I AC

output exclusively to the

I AC

input of the

CPC 100

►

Before connecting the

CP CU1

with the

CPC 100

, turn off the

CPC 100

either by the

POWER ON/OFF switch or the Emergency Stop button.

►

Set the current range switch on the

CP CU1

front panel only when the

CPC 100

is turned

off and the test object is grounded.

►

In addition to the above safety rules follow the application-specific “Safety Instructions for
Connecting

CP CU1

to Power Lines” in the CP CU1 Reference Manual.

►

The

CP CU1

may be used only as described in “Applications” in the CP CU1 Reference

Manual. Any other use is not in accordance with the regulations. The manufacturer and/or
distributor is not liable for damage resulting from improper usage. The user alone assumes
all responsibility and risk.
