INSTALLATION INSTRUCTIONS
Model VN2001-A1
Ethernet Module (10/100 BaseTx)
The optional Model VN2001-A1 Ethernet Module (10/100 BaseTx) is an interface card which provides dual
interconnecting copper wire links for networked systems.
FEATURES
The principal features of the VN2001-A1 (10/100 BaseTx)
include:
Is easily plugged into the host card or assembly
Is automatically identified by the system at power up
Protects the Ethernet signal path from overvoltage caused by electrostatic
discharge (ESD) or electrical fast transients (EFT)
Provides optimal ground fault detection (user selectable)
Provides Power-over-Ethernet (PoE), 24V, 500mA (user
selectable)
Can be used in the UL and ULC markets
PRE-INSTALLATION
1. Determine from the site-specific shop drawings whether the VN2001-A1 should be set for ground fault
supervision alone, Power-over-Ethernet (PoE) plus ground fault supervision, or neither function.
2. For ground fault supervision alone, set the jumpers as illustrated in Figure 2a. For Power-over
Ethernet plus ground fault supervision, set the jumpers as illustrated in Figure 2b. If neither ground
fault supervision nor PoE is required, set the jumpers to the default setting as illustrated in Figure 2c
a. Ground Fault Only
b. Power-over-Ethernet and
c. Open (default setting)
