Introduction

1. Introduction

1. 1 Isolated Power Panels

Bender isolated power panels provide isolated, ungrounded power to electri-

cal systems in operating rooms and other critical areas in healthcare facilities.

Isolated power systems allow for early detection of hazardous current while

keeping the system online. The system gives a visual indication of the level of

current in milliamperes (mA). When the threshold is reached, a visual and audi-

ble alarm is activated.

An isolation transformer serves a single operating room, except when supply-

ing power to equipment requiring 150 VAC or higher. A line isolation monitor

(LIM) indicates possible leakage current from all isolated conductors to

ground.

This manual provides instructions on installing and operating isolated power

panels. Refer to all relevant national and local codes and standards before pro-

ceeding with installation.

Safety Instructions

2. Safety Instructions

2. 1 General Safety Warning

Hazard of Electric Shock, Burn, or Explosion

Only qualified maintenance personnel should operate or service this equip-

ment. These instructions should not be viewed as sufficient for those who are

not otherwise qualified to operate or service this equipment. No responsibility

is assumed by BENDER for any consequences arising from use of this docu-

ment.

Turn OFF all sources of electric power before performing any inspections, tests,

or service on this equipment. Assume all circuits are live until they have been

properly de-energized, tested, grounded, and tagged. Failure to observe these

precautions will result in equipment damage, severe personal injury, or death.

Proper operation of this equipment depends on proper installation. Refer to

NFPA 70, NFPA 70E, CSA Z462, and other relevant standards and codes for

installation standards. Neglecting fundamental installation techniques will

result in equipment damage, severe personal injury, or death.

Do not make any modifications to the equipment. Failure to observe this pre-

caution will result in equipment damage or personal injury.

Use only manufacturer’s and manufacturer recommended accessories with

this equipment. Failure to do so may damage the equipment beyond repair.

DANGER

Safety Instructions

2. 2 Using This Manual

Read these instructions carefully and become familiar with the equipment

before attempting to install, operate, or service it. Throughout this manual,

special messages may appear to warn of potential safety hazards or to call

attention to information which clarifies instructions or procedures. Observe all

safety messages that appear throughout this manual to avoid possible injury

or death. An explanation of these symbols is given below.

DANGER: Indicates a hazardous situation which, if

not avoided, will result in death or severe injury.

WARNING: Indicates a potentially hazardous situa-

tion which, if not avoided, may result in death or injury.

CAUTION: Indicates a potentially hazardous situation

which, if not avoided, may result in injury or equipment

damage.

NOTE: Provides additional information to clarify in-

structions for a product or procedure.

Model Types

3. Model Types

3. 1 MIP / MIE Series Isolated Power Panels

Single-system, single-output-voltage isolated

power panel. MIP designation is used for pan-

els rated 10 kVA or below. MIE designation is

used for panels rated 15 kVA or above.

3. 2 MIC Series Isolated Power Panels with Circuit Control

Single-system, single-output-voltage (of

at least 150 V) isolated power panel. Pro-

vides programmable control of up to

twelve (12) individual circuits. Commonly

used with 208 VAC or 240 VAC portable

medical equipment, such as lasers. Circuit

control logic is configured at the factory.

Model Types

3. 3 MID Series Dual Output Voltage Isolated Power Panels

Isolated power panel for a single-input-

voltage and dual-output-voltage system.

Commonly used to simultaneously supply

power to both normal line powered

equipment and equipment operating at a

voltage greater than 150 VAC (such as por-

table medical lasers).

3. 4 MIX Series Dual System Isolated Power Panels

Two MIP series interiors installed side-by-

side in a common enclosure. In figure

below, the transformer access front trim is

translucent for illustration purposes.

Wire is provided with the front trim

assembly for ground bus interconnection

and transformer terminal block connec-

tions to panel board lugs (or sub-feed

lugs, if applicable).

Components

4. Components

The following sections describe key components of isolated power panels.

These components are standard for the United States unless otherwise noted.

Ensure equipment conforms to all national and local codes and standards

prior to purchasing.

4. 1 Backbox Package

The backbox meet the requirements of NEMA

Type 1 according to UL 50. It is fabricated from a

minimum 14 GA galvanized steel and is

designed for flush (recessed) or surface mount-

ing. Flush mounting is standard. Surface

mounted backboxes must be requested during

the purchasing process.

Surface mounted backboxes are finished with a

coat of hospital grade ivory baked enamel or

equivalent.

All backboxes include an easy-lift-off hinge

assembly to ease front trim installation and sys-

tem maintenance.
