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.

Components
4. 6 Line Isolation Monitor (LIM)
All panels are supplied with one or more line
isolation monitor (LIM). The LIM monitors the
system impedance to ground of the entire iso-
lated power system. The impedance to ground
is used to calculate the total hazard current
(THC), given in units of milliamperes (mA).
The factory default THC alarm is set to 5 mA. The
value may be changed to 2 mA to meet applica-
ble certification requirements.
The LIM is installed on the front trim in a conspicuously visible location. Refer
to LIM user manual for more information on operation and use.
4. 7 Fault Location (EDS) Kit
Panels may include branch circuit fault location
as part of an optional accessory kit (EDS kit). The
system works together with the LIM2010 to
assist in identifying the specific circuit contribut-
ing to the total hazard current alarm. Fault loca-
tion is automated (unless otherwise configured)
once the total hazard current alarm is activated.
The EDS kit is installed in the interior assembly
and may be installed at the factory or on site.
Refer to panel add-on user manual for more
information on installation, operation, and use.

ceeding with installation.
Of particular importance is minimizing the cumulative system leakage current
in an isolated power system. NFPA 99 mandates an isolated power system’s
total line-to-ground insulation impedance shall exceed 200 kΩ. Excessive leak-
age current may result in non-conformance with this requirement.
NOTE: In addition to adhering to all national, local,
and project-specific requirements, the installer shall
thoroughly review and understand all information
within this manual and relevant reference material.
Applicable material includes, but is not limited to:
• NFPA 99 - 2012: Healthcare Facilities Code Chapter 6
• NFPA 70: National Electric Code (NEC), Article 517
• (Canada) CSA C22.1: Canadian Electrical Code (CEC,
CE-Code), Section 24
• (Canada) CSA Z32: Applications of Electricity in
Healthcare

Installation
7. 2 Mount Backbox
The manufacturer recommended mounting method is to secure the backbox
to a rigid support structure (strut channel, etc.) using minimum 5/16”commer-
cial grade hardware (not included). Mounting locations are near the four cor-
ners of the enclosure sidewalls. Refer to figure on the following page for
example location in the top left corner. Note the following requirements for
each corner:
• Use two (2) 5/16”fasteners per corner on the side wall of the backbox
• Must be 2” (51 mm) from the top of the backbox
• Must be 2” (51 mm) from the front of the backbox
• Screws must be 2”(51 mm) apart
For flush-mounted enclosures, install flush with finished wall or recessed no
more than 1/8”(3 mm).
NOTE: Before installing, check the part number to ver-
ify the backbox to be installed matches with the appro-
priate interior, transformer kit, and front trim. Most
backboxes are identical in appearance.
CAUTION: Do not over-tighten the mounting hard-
ware. Over-tightening will cause distortion, misalign-
ment of the front trim, and improper hinge
functionality. Use shims to mitigate distortion as need-
ed.
NOTE: Recessing enclosure more than 1/8” (3 mm) will
impede hinge functionality.
