Thank you for purchasing UMA's EL instrument lighting system. The white light system only is PMA’d under STC#
SA01640NY* The enclosed bezel is designed to fit a 2 1/4" or 3 1/8" standard aircraft instrument. A DC to AC inverter is required to operate the bezel. UMA offers inverters in several input voltages (see chart on back). The enclosed connector kit is designed to be used in conjunction with UMA EL Bezels. (see diagram 2)
INSTRUCTIONS: PLEASE READ ALL DIRECTIONS BEFORE STARTING! Place the bezel between the instrument
and the panel, or between the panel and the panel overlay. Use 20-24 AWG twisted pair wires or shielded for all connections
between inverter and lights. If you are using shielded wire, connect all the shields together near the inverter and connect to ground
at the inverter ground connection. One UMA inverter will power up to twelve bezels (and/or UMA internally lit instruments ).
Refer to diagram 1 on back for instrument wiring references. When using a dimmer, connect it between the inverter and
aircraft power to vary the DC input together with 1Amp fast acting fuse. If connecting to an existing dimmer circuit, some modifications to aircraft wiring may be necessary. Contact UMA for information.
To install the connector kit on bezel; Refer to diagram 2 on back for details.
1. Position the EL Pigtail with the Locking Tabs on the Connector Sockets facing up. Align the Male Connector Housing with
the small Raised Boss facing up. Center it on the EL Pigtail and slide the sockets into the slots in the wide end of the male housing.
Be sure it locks (snaps) into place. [Note: If it does not lock into place, flip the male housing over and reinsert]. Take note of
which two slots the sockets slide into (Positions 3 & 1, or 3 & 2). 2. With the labeled side of the Female Connector Housing
facing up and the Locking Tab on the Connector Pin (attached to the blue wire) facing down, slide the connector pin into the
proper slot (1or 2 as determined above) of the female housing until it locks (snaps) into place. [Note: Pin orientation will be the
same as the pin that has been inserted into slot 3]. Twist (a minimum of 8 turns per foot) blue&violet wires of the connector kit together and attach to the EL light inverter wiring harness (See Inverter Instructions). Be sure to insulate all wire connections with
heat shrink tubing, or equivalent. When installing more than one bezel, wire them in parallel. 3. Snap the two Connector Housings
together. 4. Use the supplied tie-wrap to secure wiring to gauge by placing wrap close to the connector on the harness side of the
connector and route the tie-wrap completely around the gauge body and tighten securely.
*Installation Eligibility is Raytheon Aircraft Company (Beechcraft) 65-A90-1 and 65-A90-4.
