Basler Electric DGC-2020 - Manual (Page 377)

The RJ-45 socket mates with a standard Ethernet cable and provides local communication between the
LSM-2020 and a PC running BESTCOMSPlus
® software. This allows for setting of the LSM-2020 and for
the DGC-2020 that the module is connected to.
LSM-2020 connections are made with an 18-position connector with screw-down compression terminals.
This connector plugs into a header on the LSM-2020. The connector and header have a dovetailed edge
that ensures proper connector orientation. Also, the connector and header are uniquely keyed to ensure
that the connector mates only with the correct header.
Caution
By mating conductors of dissimilar metals, galvanic corrosion could
occur which may lead to signal loss.
Connectors and headers may contain tin- or gold-plated conductors. Tin-plated conductors are housed in
a black plastic casing and gold-plated conductors are housed in an orange plastic casing. Mate
connectors to headers of the same color only.
Connector screw terminals accept a maximum wire size of 12 AWG. Maximum screw torque is 4 in-lb
(0.45 N
•m).
Operating Power
The LSM-2020 operating power input accepts either 12 Vdc or 24 Vdc and tolerates voltage over the
range of 6 to 32 Vdc. Operating power must be of the correct polarity. Although reverse polarity will not
cause damage, the LSM-2020 will not operate. Operating power terminals are listed in Table 9-1.
It is recommended that a fuse be added for additional protection for the wiring to the battery input of the
LSM-2020. A Bussmann ABC-7 fuse or equivalent is recommended.
Table 9-1. Operating Power Terminals
Terminal Description
P2-1 (CHASSIS) Chassis ground connection
P2-2 (BATT+) Positive side of operating power input
P2-3 (BATT–) Negative side of operating power input
Note
To comply with the requirements of EN 55011 (Radiated Emission), wiring
connected to LSM-2020 terminals BATT+ and BATT– must be shielded.
Shielding must be grounded at one end.
Analog Inputs
These inputs can be used for var, PF, or kW control. Analog input terminals are listed in Table 9-2.
Current input connections are shown in Figure 9-4 and voltage input connections are shown in Figure 9-5.

Terminal Description
P2-9 (V+) Voltage input used for var, PF, or kW control.
P2-8 (IN–) Common for voltage or current.
P2-7 (I+) Current input used for var, PF, or kW control.
