Magtrol Model 5300 Three Phase Power Analyzer

Chapter 1 - Introduction

INSTALLATION

RIENTATION

The 5300 PA must be mounted within ± 20 degrees

from horizontal. This ensures proper operation of the

mercury shunt bypass relays.

ELECTRICAL LOAD

Use wire rated for the maximum load current and voltage

expected.

Hint: Use wire gauge large enough to ensure good

connector set screw compression on the wire leads.

Soldering may be used instead of, or in addition to the

set screw.

IEEE-488 (GPIB)

Use only high quality shielded cable conforming to the

bus standards.

INITIAL CHECKOUT

1. Make sure the circuit is completely de-energized

by removing all voltage sources.

2. Plug the 5300 PA into the 50/60 Hz power mains.

3. Switch the POWER rocker switch (red) to ON and

observe that the digit readouts flash on-off-on and

then indicate zero or a small number.

4. The VOLTS and AMPERES range switch indicator

lights will all illuminate. The voltage ranges will

sequence down from 600 through 150, and the

current ranges will sequence down from 100 through

5. The 150 Volt and 5 Amp and AUTO indicators

remain illuminated. The MODE indicators will not

light during this power-on sequencing.

6. Your 5300 PA has passed the initial check.

TRANSIENT OVERLOADS

Connect an appropriate transient suppressor in parallel

with all inductive loads. Consult the suppressor vendor's

application literature for proper selection and sizing.

Damage to the 5300 can result from

excessive voltage transients generated

by unsuppressed inductive loads. This

damage is not within the scope of the

normal instrument service and is not

covered by the Magtrol Warranty.

CURRENT OVERLOAD

There are no fuses in the 5300 PA measuring circuits.

Therefore, excessive current passed through the AMPS

terminals will cause excessive internal heating and

possible unit damage.

This overload abuse is not covered by

the Magtrol Warranty.

Know your load conditions and double check all

connections. If an overload should occur, immediately

remove all power, and locate and correct the problem

before re-energizing your circuit. If a circuit breaker is

installed, it must be installed on the LOAD side of the

5300 (downstream). This will keep the low impedance

of the input line connected to the 5300 PA for surge

suppression. If the line side must also contain a breaker,

it should be delayed in operation to open after the load

side breaker has opened.
