NOTE: Honeywell recommends adding a termination resistor for BACnet at the executive's communication and termi-
nals as well as the last module on the network. These termination resistors are required on each end of the net-
work daisy chain.
Refer to the following steps when wiring:
1. Connect communications network wiring to remote modules using the polarity guidelines provided above.
2. Always use communications wire specified for EIA/TIA 485. (Novar Part Number 33201001)
3. Always use proper RS-485 wiring techniques (e.g. Daisy chain) when wiring remote modules.
4. Make sure RS-485 wiring connected to the controller is routed through ducting to prevent physical access.
5. If the shield is to be earth grounded, tie the shield terminal to ground at the xcm.10S for Novar ES3.S and see Fig. 7
and Fig. 8 for grounding.
6. If the expansion interface is used, secure wiring using the Wire Clamp provided on the left side of the Novar ES3.S
(See Fig. 6).
CHECKING INSTALLATION
Hardware
When the unit has been mounted and the wiring connections have been completed, the procedure provided below can be
used for the initial power up and checkout.
1. Make sure power wiring to base-plate is ready.
2. Verify that the unit is seated on the base correctly and that (if used) the HOA Lockout bracket has put all switches
into the down (auto) position. Power will be applied upon completion of this step.
3. Verify Ethernet cable is connected.
4. Check the status of the LEDs. See "Assembly Board Details" on page 9.
