ERM Installation
To install the Environmental Rack Monitor (ERM):
1.
Connect the supplied straight-through CAT 5 network cable from
the ERM’s RJ-45 connector (labeled “TH-Module-1”) to the
TH-Module’s RJ-45 connector (labeled “010101”). See Figure 3 on
page 6.
NOTE
If the supplied straight-through CAT5 network cable is not long enough for your
application, you may substitute a longer cable (not to exceed 20m/65.6 ft).
2.
If applicable, connect external contact closure inputs to the screw
terminals on the TH-Module (see Figure 1 and Table 1).
NOTE
Contact closure device 1 is connected between Pins 1 and 2. Device 2 is connected
between Pins 3 and 4 (as labeled to show device 1 and 2). Contact closure devices may be
normally open or normally closed.
