OnLine Power PBC I - Manual (Page 10)

• Alarm cable
The PBC units come with an Alarm Cable, 20 feet long, which connects to the DB-9 jack so the signals are
available for external monitoring/status reporting equipment. The wiring of the cable matches the pin out detail
as shown in Illustration 1-2 for the DB-9 jack.
• DB-9 Connector Color Code:
• The normal contactact condition is generally shown with power OFF.

9 Green of Black / Green Input Failed Normally Closed
• Intrusion Switch
An intrusion alarm switch resides within the cabinet to relay that unwanted entrance into the cabinet as been
made. The plunger of the switch is in by the door when it's closed. In this condition, the switch presents an
open circuit and the alarm is in the “off” state. When the door is open, the switch presents a closed circuit and
the alarm is in the “on” state. One additional state is available on the switch. A technician working on the unit
can pull the plunger out to a “neutral” position. The switch will be in the open state ( “off” ) and thus no alarm
condition by-passed while he or she is working on the unit. See Illustration 1-3 for its location.
• ESD Receptacle and Wrist Strap
The ESD wrist strap plugs into the red connector receptacle on the front panel of the Electronic Tray. An ESD
wrist strap is in the bottom of the cabinet. Any personnel working on the unit should be wearing the strap. The
strap plugs into the RED banana plug receptacle to minimize the risk of damage to the ESD sensitive circuitry
that of the electronics assembly.
1-3 Ruggedization Features
All PBC’s designed to operate in most outdoors harsh environments. The unit has been subjected to outside
independent labs to demonstrate that they are capable of withstanding severe outdoors operating conditions.
Below is a listing of many of those conditions:
