PS-5N7 Cabling Diagram in the RCC-1/-1F Enclosure (With a PIM-1)
When using a PIM-1 Module with the
PS-5N7 in an RCC-1/-1F Enclosure (See
Figures 4 and 5):
1. Mount the PS-5N7 to the right of the
PIM-1 in the bottom of the enclosure.
2. Refer to the RCC-1/-1F Installation
Instructions, P/N 315-095364, for
instructions on the cabling connections.
For additional information refer to
the PIM-1 Instructions, P/N 315-091462.
Power Connection
The PS-5N7 requires a DC input of 14-31 VDC.
This input is available from the MMB or the
PSR-1. Refer to Figure 5 for the correct
wiring instructions.
Using the PS-5N7 with Style 4
(2-Wire) Network Connections
Use screw terminals 1 and 2 for Network A.
DO NOT USE wire terminals 3 and 4 in this
configuration. See Figure 5 for additional
wiring information. Refer to the PSR-1 Instal-
lation Instructions (P/N 315-090911) for more
details on Style 4 networks.
Figure 4
Using PS-5N7 with Style 7
(4- Wire) Network Connections
Do not place the PS-5N7 module in the last
position on a Style 7 Network. Use a NET-7
at each end of the network to provide proper
supervision.
Use screw terminals 1 and 2 for Network A,
terminals 3 and 4 for Network B. Refer to
Figure 5 for wiring instructions.
Wiring Restrictions
Network
The MXL supports a maximum of 64 network
nodes. Each module in the list below repre-
sents one node. Do not plan a system with
more than 64 of these modules.*
MMB (one allowed per system)
MOI-1
NET-4
NET-7M
The total wire resistance in both wires of the
network pair cannot be more than 80 ohms.
*If the system has more than 32 nodes, an
REP-1 module must be used.
