WARRANTY
Subject to the terms of this paragraph, the supplier warrants its title to the products sold by it and
warrants to the Purchaser that its products are free of defects in workmanship or material and are in
conformity with applicable specifications and descriptions of the supplier. No claim shall be maintained
hereunder unless the facts giving rise to it are discovered within 16 months from the date of shipment
from the factory, or 12 months after initial energization of said equipment, with the one expiring first
given precedence, and written notice thereof given to the supplier within 30 days of discovery. The sole
and exclusive liability of the supplier, for Breach of Warranty shall be, at its option, to replace or repair
the product or part concerned F.O.B. its factory or such place as it may designate. The warranties stated
in this paragraph are exclusive of all other warranties, written or oral, statutory, expressed or implied,
none of which shall apply to the sale of the suppliers products hereunder.
0-10V Outputs and Non-isolated Fixture Drivers
Connection of the E-Flex relay panel 0-10V analog dimming outputs to non-isolated fixture drivers is not
recommended. The E-Flex is designed to provide sinking control of fixtures that have a secondary Class 2
dimming circuit that is isolated from the mains power. Connection of the E-Flex 0-10V analog outputs to
non-isolated drivers, or drivers with Class 1 rated dimming circuits, will cause damage to the relay panel.
This damage is considered non-warranty.

E-Flex User Manual, Rev. 1.30
Glossary of Terms
Demand Response -
Energy codes and energy companies have growing requirements to reduce your power consumption
during high-energy usage. The Room Controller meets these energy requirements by accepting a contact
input from the power company to impose a maximum output per zone.
LightsOut -
LightsOut is the period of time when lights should be at the LightsOut preset (typically, Off) unless there
is user intervention. Before activation of the LightsOut preset, lights will flash three times to warn
occupants of the upcoming change. After a delay the LightsOut preset will be activated. During this
delay, any button press at any station will further delay the activation of the LightsOut preset. Once the
LightsOut preset is in effect, light levels may be changed by a user. After 15 minutes of no inactivity, the
LightsOut sequence will start again.
Occupancy Mode –
Automatically turn lights ON when the occupancy sensor input detects the presence of a person and will
automatically turn lights OFF when no presence is detected for a specified amount of time.
Vacancy Mode –
Lights must be turned on manually by someone entering a room or area. The system will then
automatically turn lights OFF when no presence is detected on the occupancy sensor input for a
specified amount of time.

Installation
Shipment Inspection
Check the shipment before beginning installation and confirm that it has arrived complete and
undamaged.
Check the shipping container for any physical damage. If there is any damage found, document
it to help with any claim against the shipper.
Check the contents of the shipping container against the packing list and ensure that the order is
complete. If there are any discrepancies with the contents of the shipment, contact Lehigh
customer service.
Mounting
Mount the panel to the wall using the four ¼” keyhole slots in the rear of the enclosure.
Suitable for indoor use only on a vertical surface.
Mount the panel in an accessible location to allow for end use programming or relay bypassing.
Circuit Breaker Protection
Prior to installation of the E-Flex relay panel make sure that you have installed a main circuit breaker
cabinet or other input power disconnect.
Warning:
Without an Accessible power disconnect (breaker) the E-Flex relay panel
cannot be operated or serviced safely.
Terminations and Conduit Access
All terminations are accessible from the front of the controller with the cover removed.
High voltage knockouts are provided on the right side for relay power, opposite each relay
terminal so that individual feeds can more easily be provided.
High voltage knockouts are also provided on the top and bottom right for either feeders or
control power.
Low voltage knockouts are provided on the top and bottom left side.

E-Flex User Manual, Rev. 1.30
Wiring Requirements
Note:
All line voltage wiring must be in conduit or use other approved wiring
methods, and the cabinet must be grounded using the ground stud connection.
Low voltage wiring must be run in separate conduit from input power.
High voltage Wiring
Warning:
RISK OF DEATH OR ELECTRIC SHOCK! Before installing input power to the
controller, make sure upstream source of power is off.
Warning:
A high voltage shield covers the right side of the controller to serve as a
mechanical barrier to provide voltage separation inside the panel enclosure of
the low voltage wiring from the high voltage wiring. This shield must be
removed for high voltage termination and must be reinstalled when
termination is complete.
Remove two screws at top and bottom center of the main controller board to remove the high voltage
shield. For an 8-circuit panel an additional shield must be removed for circuits 5 thru 8.

Low Voltage Wiring
Follow all national and local codes for separation requirements. Do not combine Class 2 and Class 1
wiring. Low voltage control cables must be run in separate conduit from input power wires.

system.
Emergency Input
The Emergency UL924 contact input requires a normally closed contact that will open upon loss of
normal power. When the emergency input is activated (opened) the following can be expected for each
output of the relay panel:
For outputs that are assigned to the emergency input, the relay will close and the 0-10V output
will be driven to 100%.
Outputs not assigned to the emergency input will remain at their current level.
Emergency Enable/Disable (EMERG-J12)
Jumper J12 (EMERG) is used to enable or disable the emergency input. To enable, position the jumper
across J12 pins 1-2. To disable (default) position the jumper across J12 pins 2-3.
