7 STARTUP

General

— This section lists the procedure for applying power to an

FP-5000 for the first time. Use it as a checklist to reduce the chance
of skipping an item.

DANGER

ONLY QUALIFIED PERSONNEL FAMILIAR WITH THE FP-5000,
THE BREAKER, AND ITS ASSOCIATED MECHANICAL EQUIP-
MENT, SHOULD PERFORM THESE STARTUP PROCEDURES.
FAILURE TO COMPLY CAN RESULT IN SERIOUS OR FATAL
INJURY AND/OR EQUIPMENT DAMAGE.

CAUTION

NEVER HIGH POT THE FP-5000 CIRCUITS BEYOND
1500VRMS/1 MIN. DO NOT USE A MEGGER

, HI-POT, OR

OTHER HIGH VOLTAGE INSULATION TESTER ON THE FP-5000
TERMINALS, IT HAS BEEN FACTORY TESTED, AND FIELD
TESTING MAY CAUSE UNNECESSARY STRESS. REMOVE THE
FP-5000 INNER CHASSIS WHEN TESTING THE PROTECTIVE
RELAY SYSTEM.

CAUTION

DO NOT USE A MEGGER

, HI-POT, OR OTHERWISE HIGH

VOLTAGE TO TEST THE FOLLOWING TERMINALS OR POINTS:
• TB3 - J1-3 SHIELD – IS BONDED TO HOUSING

(FILTER CLAMP)

• TB3 - J2-3 SHIELD – IS BONDED TO HOUSING

(FILTER CLAMP)

• TB3 - J3-5 SHIELD – IS BONDED TO HOUSING

(DIRECT GROUND)

• TB2 - 218 VG (REF.) – IS BONDED TO HOUSING

(FILTER CLAMP)

• FRONT RS-232 PROGRAMMING PORT SHELL – IS BONDED

TO HOUSING (DIRECT GROUND)

Startup consists of Programming the necessary operational
parameters, verifying the operation of the FP-5000, checking the
wiring, and verifying the reasonable operation of the system
components before attempting to place the equipment into
continuous service.

The programming should already be done before FP-5000 is placed
into service. Protection parameters may be reviewed in the View
Settings mode or adjusted in the Set Mode.

Refer to wiring

Figures 2-2

and

2-3

and

Figure 6-5

on terminal

definitions, Section 3 “Specifications” for nominal ratings during
startup.

7.1 Power-Off Checks

With the incoming AC distribution power locked off and after all
sources of power to the FP-5000 are de-energized, including control
system battery, check the wiring for conformance to the wiring plan
developed for the application.

• Verify that the Ct secondary current rating and the FP-5000 Ct

input rating style agree (either 5A or 1A). See Section 1.8
Ordering Information for catalog number identification.

• Verify that the Voltage Inputs are referenced to Voltage transform-

ers where the common is earth ground. TB2 Terminal 218 “Vg” is
internally bonded within the FP-5000 to protective earth and can
not be connected to neutral or a phase reference.

WARNING

VOLTAGE TRANSFORMERS ARE OFTEN CONNECTED
“UPSTREAM” FROM THE BREAKER CIRCUIT MONITORED
AND SO MAY BE DIFFICULT TO DISENGAGE.

7.2 Initial Control Power-On Checks

• All power sources should be disconnected as described in Section

7.1.

• Disable all trip and control circuits.

• Disconnect and insulate the breaker trip coil load leads from any

of the trip relay terminals, typically Relay1 and Relay2 on TB1
terminals 116 and 118, to prevent breaker from energizing during
most of this testing.

• Disconnect and insulate any control circuit loads connected to the

remaining control relays on the FP-5000.

• Verify FP-5000 power supply control power:

– Disconnect the AC or DC control power lead to terminals

TB101(+).

– Connect a voltmeter to the circuit that fed TB101 and the

return on TB102.

– Energize the FP-5000 power supply power source

and monitor the voltage.

– Make sure that it is within nominal specifications:

– Battery system 48 – 125V DC or

control power transformer 100 – 120V AC.
