The following is a list of actions to review when planning a JCOMM installation.
JCOMM enclosure installation
1. Select power distribution equipment to be monitored by JCOMM BCMSs.
2. Based on (1), determine the number of JCOMMs required (specified on order).
3. Select the location of each JCOMM and determine mounting method, conduit, and mounting hardware.
The customer provides all conduit and mounting hardware. (See paragraph
4.2 Install the JCOMM Enclosure )
a. Typically a JCOMM will be attached directly to a PDU or RPP or to a nearby wall.
b. Plan conduit and CT cable harness lengths from JCOMM to circuits. If running cables from under a
monitored unit, make provision for cable bends to create correct branch circuit addressing. (See
paragraph
4.5 Install Panelboard Branch Circuit CTs )
4. For power/voltage connections, the customer must provide
a. An approved electrical disconnecting means on each voltage source within sight of the JCOMM in
accordance with local codes and NEC standards. (See paragraph
4.3 Connect Ground and Voltage Sources )
b. A ground connection in accordance with FIPS Pub 64, NEC standards, and local codes.
Monitors: local power monitoring stations
5. Determine monitors to be used as local power monitoring stations:
a. Determine which JCOMMs will have a display.
b. Determine which BCMS devices will be monitored downstream of the display (panelboards and
subdistribution feeds).
c. Alternatively, determine if JCOMM BCMSs will be connected to a WaveStar BCMS Hub.
Communications
6. Determine protocols to be used between the JCOMM monitors and the building management system
(BMS). (See paragraph
5.2 Upstream Protocols Using a Monitor )
7. Plan communications cables (type and length) and BCMS upstream links to the BMS. Customers must
provide all communications cables for connections upstream or downstream of a JCOMM. (See paragraph
5.1 Modbus Network Setup )
8. Create a Modbus address map. Incorrect network addressing is a common BCMS startup problem. If
using a JCOMM monitor or WaveStar BCMS Hub with a Modbus upstream protocol, plan for downstream
Modbus addresses to be remapped upstream from monitors. (See paragraph
5.5 Remapping Modbus Addresses with Monitors )
Monitoring options
9. Select a points list. Points lists must be specified at time of order for loading into the BCMS boards. (See
paragraph
7.2 Panelboard Points Lists )
10. Plan setup options, especially warning and alarm parameters. (Review all of )
