Warning/Caution Notations

WARNING:

Personal injury/loss of life may

occur if you do not follow the

procedures as specified.

CAUTION:

Equipment damage, or loss of

data may occur if you do not

follow the procedures as

specified.

Prerequisites

• Check for shipping damage. In the event of

damage, contact the transport company.

• Locate the E-Bypass option nameplate and

confirm the unit is configured to installation

requirements.

Installation

CAUTION:

On installation of a SED2 after extended

storage, see the Extended Storage:

Conditioning of Capacitors section in the

SED2 VFD Startup, Operation, and

Maintenance Manual (125-3201). If

capacitors are not properly recharged,

catastrophic damage to the drive can

result.

Environmental Conditions

Install the E-Bypass Option in a heated, indoor

controlled environment that is free of moisture and

conductive contaminants such as condensation and

dust.

The air entering the unit for ventilation/cooling must

be clean and free from corrosive materials.

The ambient temperature must be between 14°F

and 104°F (-10°C and 40°C), and the relative

humidity must be 0° to 95° non-condensing.

NOTE: Do not mount unit in direct sunlight.

CAUTION:

Height above sea level: If installing a

SED2 at an altitude of higher than 3280 ft

(1000 m), derating is required.
