1-2-4 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-II are 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:
1-3-1 Wide Temperature Range
The PBC-II designed and tested to operate in the outdoors over a wide range of temperatures, from -40 0 C to +46 0 C
plus a solar load of 70 watts/sq.ft. The PBC-II unit has option of having internal heaters for the batteries to allow it to
operate over a range of -40
0 C to +46 0 C.
1-3-2 Shock and Vibration
These devices are designed and tested to meet Bellcore specs for shock and vibration namely GR-63-Core Issue 1
section 4.3 and GR-63-Core issue 1 section 4.4 and earthquake zone 4.
1-3-3 High Input Voltage Surge Withstand Capability
The unit internally has AC Surge protector (ACT’s TVSS) to ensure that lightning or other types of high voltage
surges do not damage them. They meet IEEE 62.41 1991 (UL1449) level C3 input voltage surge, of 20,000 Volts @
10,000 Amps.
1-3-4 Corrosion Resistant Cabinet
The cabinet is aluminum - anodized and painted on the exterior. It is a sealed cabinet having drain holes at the
bottom and vents for hydrogen gas at top.
1-3-5 Rain-Proofed Cabinet
The cabinets designed and tested to meet UL50 (Type 3R) and IEC60529 (IP34) requirements and thereby to
ensure that rain will not reach the critical electronics.
1-3-6 Easy Front Door Access
This makes for effective field service access.
