PRL3a Panelboard TVSS Unit Removal

and SPD Installation Instructions

EATON CORPORATION www.eaton.com

Section 1: Introduction

These instructions will guide you through the process of replacing an

existing Eaton Visor, CVL, or SML transient voltage surge suppres-

sor (TVSS) unit with an SPD Series surge protective device (SPD).

These instructions are specific to the replacement of those devices

when integrated within an Eaton PRL3a panelboard. Because SPD’s

vary in application (bus connected versus interfaced through a circuit

breaker, 3-phase versus single-phase, etc), the pictures utilized in

this document may not be reflective of your specific application.

Please read all instructions carefully as you perform each step. If

you require any support throughout the replacement process, please

contact the Eaton Technical Resource Center at 1-800-809-2772,

Option 4, Option 2.

1.1 PRL3a Panelboard Preparation

 DANGER

HAZARDOUS VOLTAGES WILL CAUSE SEVERE INJURY OR DEATH. TURN

OFF ALL POWER SUPPLYING THE PANELBOARD BEFORE REMOVING THE

TVSS UNIT AND INSTALLING THE REPLACEMENT SPD. USE A METER TO

ENSURE THAT NO VOLTAGE IS PRESENT IN THE PANELBOARD BEFORE

MOVING FORWARD WITH THESE INSTRUCTIONS.

1. Remove the panelboard trim and hardware. Keep the trim and

hardware for re-installation.

2. Identify the TVSS unit that is to be removed and replaced. If it is

a Visor, move to Section 2.1. If it is a CVL/SML, move to

Section 2.2.

assembly from the panelboard. Remove each Item 5 bracket by

removing the Item 15 screw (two places). Discard all hardware

and miscellaneous parts removed during the process.

ote:N For top incoming applications, there is a bus support located directly

above the area from which the Visor was removed. For bottom incoming

applications, there is a bus support located directly below the area from

which the Visor was removed. This bus support will be used as a reference

point when locating the new SPD assembly (Figures 4 and 8).

2.2 CVL/SML Disassembly Instructions

ote:N Refer to Figure 3 while performing all CVL/SML disassembly steps.

1. Remove Item 1 (dead front cover - attached by four screws).

2. Remove the panelboard dead front cover assembly and hardware.

Keep the dead front cover assembly and hardware for re-installa-

tion.

3. CVL/SML units will have either two wires (single-phase units) or

three wires (3-phase units) connected between the unit and a

circuit breaker. Disconnect these wires from the circuit breaker.

Also, disconnect the neutral wire (white/gray) from the panel-

board neutral assembly and ground wire (green) from the panel-

board ground assembly.

4. Remove the Item 6 screw (four places) and remove the CVL/SML

unit from the panelboard assembly.

ote:N For top incoming applications, there is a bus support located directly

above the area from which the CVL/SML was removed. For bottom incom-

ing applications, there is a bus support located directly below the area from

which the CVL/SML was removed. This bus support will be used as a refer-

ence point when locating the new SPD assembly (Figures 4 and 8).

Section 3: SPD Series Unit Installation

Instructions

ote:N If SPD is to be interfaced via a circuit breaker, skip to Step 10 in this

section. If SPD is to be direct bus mounted, go to Step 1 in this section.

1. Refer to Figure 4 for orientation of the Item 9 bracket. In order

to properly locate the Item 9 bracket onto chassis rail, select the

appropriate Figure 5 illustration based upon top or bottom incom-

ing direction of the panelboard main conductors. Locate the Item
