3.2.2.5 Recommended Serial Communication Cable Lengths

Connector J8 on the Regulator boards is an RSĆ232 serial communication port. This connector

allows the GV3000 drive to communicate with external devices such as a personal computer using

RSĆ232 protocol. See table A.5. Two RSĆ232 cables are available from Reliance: a 3.5 meter (12 feet)

DĆshell 9Ćpin to 9Ćpin cable (M/N 615184Ć1A) and a 0.3 meter (1 foot) DĆshell 9Ćpin to 25Ćpin adaptor

cable (M/N 615184Ć2A). UserĆconstructed cables can be up to 15 meters (50 feet) in length. Note that

for communication between a GV3000 drive and a personal computer, the Control and Configuration

software must also be used. Refer to instruction manual D2Ć3348 for more information.
The Regulator boards have one set of RSĆ232 transmit/receive lines. These lines can be accessed by

only one device at a time: connector J8, the RSĆ232 terminals (1Ć3) on the terminal strip, or an

Operator Interface module (OIM).

3.2.3 Selecting Input Line Branch Circuit Fuses

CAUTION: The NEC/CEC requires that upstream branch circuit protection be provided to protect input powĆ

er wiring. Install the fuses recommended in table 3.9. Do not exceed the fuse ratings. Failure to observe this

precaution could result in damage to or destruction of the equipment.

Input line branch circuit protection fuses must be used to protect the input power lines. See figures

5.1 and 5.2. Recommended fuse values are shown in table 3.9. The input fuse ratings listed in table

3.9 are applicable for one drive per branch circuit. No other load may be applied to that fused circuit.
