IMPORTANT

This equipment complies with the requirements in part 15 of FCC rules for a Class A computing device. Operation of this equipment in a residential area can cause unacceptable interference with radio and television reception that requires the operator to take whatever steps are necessary to correct interference.

Warning:

radio frequency energy, and if not installed and used in accordance with the Instructions Manual, may cause interference with radio communication. It has been tested and found to comply with the limits for a Class A computing device pursuant to Subpart J of Part 15 of FCC Rules, which are designed to provide reasonable protection against such interference when operated in a commercial environment. Operation of this equipment in a residential area is likely to cause interference, in which case, user at their own expense will be required to take whatever measures may be required to correct the interference. Any unauthorized modification of this equipment may result in the revocation of the owner’s authority to continue its operation.

Canadian EMI: This digital apparatus does not exceed the Class A limits for radio noise emission from digital apparatus set out in the Radio Interference Regulations of the Canadian Department of Communications.

Le présent appareil numérique n’émet pas de bruits radioélectriques dépassant les limites applicables aux appareils numériques de la Classe A prescrites dans le Règlement sur le brouillage radioeléctrique édicté par le ministère des Communications du Canada.

3. Installer must be a trained, experienced service

technician.

Check out the product after installation, as provided in the Q7700 Network Interface Unit instructions, form 632278 and S7810B instructions, form 65-0228.

5. Make sure that only the manufacturer makes repairs.

6. If trouble develops, disconnect the equipment from the

modem and determine the cause of the fault. Reconnect only when the problem is corrected.

WARNING

.Electrical Shock Hazard. Can cause severe injury, death or equipment damage.

Disconnect power supply before beginning installation to prevent electrical shock and equipment damage. More than one power supply disconnection can be involved.

Humidity

Install the Network Interface Unit where the relative humidity never reaches the saturation point. The Network Interface Unit is designed to operate in an 85 percent relative humidity continuous noncondensing moisture environment. Condensing moisture can result in improper operation.

Vibration

Do not install the Network Interface Unit where it can be subjected to excessive vibration in excess of 0.5G continuous maximum vibration.

a. Allow for an additional 2-1/2 inches (64 mm)

minimum below the Network Interface Unit for electrical connector installation.

b. Allow for an additional 1-1/2 inches (38 mm)

minimum on each side for electrical housing cover

6. Remove the ControlBus™ Module using the wire loop;

insertion and wiring.

grasp the ControlBus™ Module firmly and pull the module from the Network Interface Unit.

WIRING

Wiring Requirements

WARNING

Electrical Shock Hazard. Can cause severe injury, death or equipment damage.

1. Wiring must comply with all applicable codes, ordinances and regulations.

2. Refer to Fig. 6 for proper system wiring.

3. Do not plug or unplug any Network Interface Unit ControlBus™ Module or electrical connectors with the power on. Make sure that power is off to protect

1. All wiring must comply with all applicable electrical

against equipment damage.

codes, ordinances, and regulations. Recommended wire size and type for ControlBus™ communication is shielded 22 AWG twisted pair cable (Belden 8723 or equivalent). Terminal identification numbers and letters are shown in Table 1.

Weather

The Network Interface Unit is not designed to be weather tight. When installed outdoors, provide protection for the Network Interface Unit.

Mounting the Network Interface Plug-in Card

For installation dimensions, see Fig. 1.

Mount the ControlBus™ Module in the Network Interface Unit (see Fig. 2). Do not mount the Network Interface Unit with the Interface ControlBus™ Module edge connector slots facing down.

Insert the ControlBus™ Module with the electrical connector facing out from the Network Interface Unit.

3. Grasp the ControlBus™ Module and align the plug-in

edge card with the connector in the bottom of the Network Interface Unit.

4. Firmly insert the ControlBus™ Module into the Network

Interface Unit.

5. Select a location that can support the Network Interface

Unit. Be sure to allow clearances for servicing, installing and removing the wiring compartment cover, Network Interface Unit cover, electrical connectors and ControlBus™ Modules.

3. Wire Routing:

a. Do not route the ControlBus™ cable in conduit with

line voltage circuits.

b. Do not route the ControlBus™ cable close to the

ignition transformer.

c. Route the ControlBus™ cable outside of conduit if

properly supported and protected from damage.

d. Route the ControlBus™ cable so that all devices are

connected in a daisy chain configuration. See Fig. 6. Maximum wire lengths can be 4000 ft (1219 m) for the ControlBus™ RS-485 interface under ideal conditions.
