CAUTION: This equipment is for indoor use only and needs to be air-cooled. Mount in a well-ventilated area. The ambient temperature must be 32°F to 104°F (0°C to 40°C). The relative humidity must be 0% to 90% (non­condensing).
CAUTION: Terminal blocks and modules must be installed in the lowest slot of an enclosure. The only devices in an enclosure that may be placed beneath the block and module is the Crestron PAC2 Automation Control System or CAEN-BLOCK Termination Block. Refer to the illustrations shown for recommended installation locations.

CAUTION: RISK OF ELECTRIC SHOCK—MORE THAN ONE DISCONNECT SWITCH MAY BE REQUIRED TO DE-ENERGIZE THE EQUIPMENT BEFORE SERVICING.
1. Use the two supplied self-tapping pan Phillips screws (8B x ¼” length) to secure the terminal block and the wiring label to the Crestron Automation Enclosure. The wiring label lies beneath the terminal block as shown in the wiring diagram on this page.
NOTE: Use copper conductors only – rated 75°C.
NOTE: Both left and right wiring labels are
provided. The left-side labels are common for both single and double-wide enclosures. The right-side labels are only used in double-wide enclosures since the modules and terminal blocks along the right side must be inverted when mounting.

2. With the circuit breaker turned off, connect the circuit feeds (HOT, NEUTRAL, and GROUND) to the terminal block per the markings provided on the wiring label (as shown in the following diagram). Terminal blocks accept one 14 - 10 AWG wire. Wires should be stripped to ½ inch. Tighten terminal blocks to 9 in-lbs.
NOTE: HOT and NEUTRAL lines can be jumped to other terminal blocks in the enclosure.
3. Grounding terminal blocks are available in the cabinet for termination of ground wires. Tighten to 35 in-lbs. (14 – 10 AWG).
4. Connect each wire from the connector assembly to the terminal block. Each wire is the same color as the terminal to which it should be connected. Wires are pre-stripped to ½ inch. Tighten to 9 in-lbs.
5. Test the circuit for electrical faults by turning on the circuit breaker and checking that the breaker does not trip and that power is supplied to the connector of the cable assembly.

NOTE: Modules are to be installed after the enclosure has been completely wired. Refer to the terminal block installation procedure on page 2 for details.
1. Use the four supplied self-tapping screws (8B x ¼ length) to secure the module to the enclosure.
2. If the module is being installed below another module within the enclosure, attach the supplied module interconnect cable between the two modules. The following illustration (next page) depicts the area within a double-wide enclosure where the corners of four modules meet.
CAUTION: The module contains electrostatic sensitive devices (ESDs); unit must be handled from metal chassis – do not touch PC board or components.
NOTE: One wire on the module interconnect cable may be a different color from the rest. The color has no bearing on its orientation during installation.

4. Turn on the circuit breaker and verify that the breaker does not trip.
NOTE: If the fuse is to be replaced, replace only with the same fuse type and rating. A time lag is required.

Network Device Wiring

CAUTION: In order to ensure optimum performance over the full range of your installation topology, Crestron Certified Wire, and only Crestron Certified Wire, should be used. Failure to do so, may incur additional charges if support is required to identify performance deficiencies as a result of using improper wire.
CAUTION: Use only Crestron power supplies for Crestron equipment. Failure to do so could cause equipment damage or void the Crestron warranty.
CAUTION: Provide sufficient power to the system. Insufficient power can lead to unpredictable results or damage to the equipment. Please use the Crestron Power Calculator (www.crestron.com/calculators) to help calculate how much power is needed for the system.
CAUTION: Possible equipment damage if miswired.
NOTE: When installing network wiring, refer to the
latest revision of the wiring diagram(s) appropriate to your specific system configuration, available from the Crestron website.
NOTE: Do not power up system until all wiring is verified. Care should be taken to ensure data (Y, Z) and ground (G) connections are not crossed when connecting Cresnet devices.
When calculating the wire gauge for a particular Cresnet run, the length of the run and the Cresnet power usage of each Cresnet unit to be connected must be taken into
consideration. If Cresnet units are to be daisy-chained on the run, the Cresnet power usage of each network device to be daisy-chained must be added together to determine the Cresnet power usage of the entire chain. If the unit is a home-run from a Crestron system power supply network port, the Cresnet power usage of that unit is the Cresnet power usage of the entire run. The length of the run in feet and the Cresnet power usage of the run should be used in the following resistance equation to calculate the value on the right side of the equation.
Resistance Equation
The required wire gauge should be chosen such that the resistance value is less than the value calculated in the resistance equation. Refer to the table after this paragraph.
Wire Gauge Values
RESISTANCE
(R or Ohms)
4 16 1.50
6 18 0.75
10 20 0.50
15 22 0.34
13 Doubled CAT5
8.7 Tripled CAT5
WIRE GAUGE
(AWG) (MM2)
NOTE: All network wiring must consist of two twisted pairs. One twisted pair is the +24V conductor and the GND conductor. The other twisted pair is the Y and Z conductors.
NOTE: When daisy-chaining Cresnet units, strip the ends of the wires carefully to avoid nicking the conductors. Twist together the ends of the wires that share a pin on the network connector, and tin the twisted connection. Apply solder only to the ends of the twisted wires. Avoid tinning too far up the wires or the end becomes brittle. Insert the tinned connection into the Cresnet connector and tighten the retaining screw. Repeat the procedure for the other three conductors.
NOTE: For larger networks (i.e., greater than 28 network devices), it may become necessary to add a Cresnet Hub/Repeater (CNXHUB) to maintain signal quality throughout the network. Also, for networks with lengthy cable runs, it may be necessary to add a Hub/Repeater after only 20 devices.

Hardware Hookup

The venting holes on the sides and top of the module should not be obstructed under any circumstances. If the module is hot to the touch, consider using forced air ventilation or implementing additional supplies to distribute the load.

Hookup Preparation

Prior to making hardware connections, it is assumed that all wiring is run. This includes the connection of network connectors. However, the network connectors should not yet be plugged into the network devices. Use an ohmmeter to verify that none of the four network conductors are shorted or crossed. Furthermore, each network device must have a unique Net ID. If necessary, refer to the product documentation for the appropriate Net ID assignment procedure of each device.

Hookup Methods

The hookup diagram on the next page illustrates the home run and daisy chain methods of connecting the module. It also illustrates multiple modules within a single Cresnet system (each module must be installed in its own CAEN enclosure). Only use the methods shown; do not connect multiple power supplies together in parallel. If only one power supply is necessary, use either method connected to a control system.
NOTE: Always disconnect AC power to the module supplying power to a Cresnet system before connecting a network device to that system or installing a card in the control system.
NOTE: Never connect multiple modules in parallel.

Hookup Procedure

1. Connect each network device to the appropriate network connector on the module.
2. Connect AC power to the module.
3. If a PC (running SIMPL Windows) is available, connect the PC to the Cresnet system via the computer port on the control system.
4. Establish communications with the control system as described in the latest version of the Crestron 2-Series Control Systems Reference Guide (Doc.
6256) which is available from the Crestron website (www.crestron.com/manuals).
5. From SIMPL Windows, select Tools | Viewport to open the Viewport.
6. Select Diagnostics | Report Network Devices (alternatively F4) to verify that all network devices are properly connected to the Cresnet system.
