IMPORTANT SAFETY INSTRUCTIONS

WARNING!: TO PREVENT FIRE OR ELECTRIC SHOCK, DO NOT EXPOSE THIS EQUIPMENT TO RAIN OR MOISTURE.

• Elevated Operating Ambient – If installed in a closed or multi-unit rack assembly, the ambient operating temperature of the rack environment may be greater than room ambient. Consideration should be given to ensure that the maximum operating temperature range (0°C to 50°C) is not exceeded. However, if installing a QIO-GP8x8 in a multi-unit rack assembly with units on all sides, the maximum operating temperature should not exceed 40°C when devices are placed above or below.
• Reduced Air Flow – Installation of the equipment in a rack should be such that the amount of air flow required for safe operation of the equipment is not compromised.

CAUTION: To reduce the risk of fire, use only 26 AWG or larger telecommunication line cord with the QIO-TEL2.

16. Adhere to all applicable, local codes.
17.  Consult a licensed, professional engineer when any doubt or questions arise regarding a physical equipment installation.

Maintenance and Repair

WARNING: Advanced technology, e.g., the use of modern materials and powerful electronics, requires specially adapted maintenance and repair methods. To avoid a danger of subsequent damage to the apparatus, injuries to persons and/or the creation of additional safety hazards, all maintenance or repair work on the apparatus should be performed only by a QSC authorized service station or an authorized QSC International Distributor. QSC is not responsible for any injury, harm or related damages arising from any failure of the customer, owner or user of the apparatus to facilitate those repairs.

IMPORTANT! 24V DC power supply or Power over Ethernet (PoE) PSE required. The QIO-FLEX4A requires an IEEE 802.3 at Type 2 (PoE+) PSE or 802.3af Type 1 Class 3 PoE PSE if the device amplifier is not used. All other QIO models require an 802.3af Type 1 PoE PSE.

Power Requirements

The Q-SYS QIO Series offers a flexible power solution that allows the integrator to choose to use either a 24V DC power supply or Power over Ethernet (PoE). With either power solution, you must follow the safety instructions for the specific power supply or injector chosen. For details on the 24V DC or PoE power supply requirements, refer to the product specifications.

WARNING: To avoid the risk of electric shock, this equipment must only be connected to a supply mains with protective earth when using class I power supply.

Power over Ethernet (PoE)
The QIO-FLEX4A requires an IEEE 802.3at Type 2 (PoE+) PSE or 802.3af Type 1 Class 3 PoE PSE if the device amplifier is not used. All other QIO models require an 802.3af Type 1 PoE PSE.

NOTE: A device cannot provide daisy-chained power to an external device with Power over Ethernet. An external 24V DC supply is required for power daisy-chaining applications. A device can provide Ethernet daisy-chaining with either power source.

24V DC External Supply and Daisy-Chained Devices

NOTE: When using an accessory power supply (24V DC @ 3.75A max, less than 100W), a maximum of four (4) quarter-rack QIO devices, two (2) QIO-FLEX4A devices, or any combination of QIO devices that can fit in a single QIO-RMK Rack Kit may be powered simultaneously. For rack mounting information, see “Rack Mount Installation” on page 24.

Rack Mount Installation

Q-SYS QIO Endpoints are designed to be mounted in a standard rack-mount unit using the Q-SYS 1RU rack tray (FG-901528-00, QIORMK). The rack tray accommodates up to four quarter-rack width QIO devices or two half-rack width (QIO-FLEX4A) devices. A QIOFLEX4A unit can occupy the left, right, or center of the tray.

Retaining clips

Attach the Retaining Clips
For each QIO Endpoint you are installing in the tray, insert and attach a retaining clip in either the short (5.5”) or long (8.5”) length location using a flat head screw.

Attach the QIO Endpoints and Blanking Plates
Slide each QIO Endpoint into a retaining clip. Attach each unit with two flat head screws. Optionally attach the blanking plates, each with two flat head screws.
NOTE: Blanking plates are optional and can be used to facilitate proper rack airflow. Unused blanking plates can be attached at the rear of the tray if needed, as shown.

Surface Mount Installation

The QIO Endpoints can also be mounted under a table, on top of a table, or on a wall. For any of these mounting applications, use the surface mounting bracket and pan head screws included with the QIO Endpoint ship kit. The brackets are symmetrical to accommodate mounting right-side up to a ground- facing surface.
NOTE: Fasteners for attaching the bracket to a surface are pictured as an example but not provided.

Freestanding Installation

For freestanding installation on a table top, apply the four adhesive foam spacers to the underside of the unit.
