3.2.2.5 Recommended Serial Communication Cable Lengths
Connector J8 on the Regulator boards is an RS-232 serial communication port.
This connector allows the GV3000/SE drive to communicate with external devices
such as a personal computer using RS-232 protocol. See table A.5.
Two RS-232 cables are available from Reliance: a 3 meter (10 feet) D-shell 9-pin to
9-pin cable (M/N 2CA3000) and a 0.3 meter (1 foot) D-shell 9-pin to 25-pin adapter
cable (M/N 2CA3001). User-constructed cables can be up to 15 meters (50 feet) in
length.
Note that for communication between a GV3000/SE drive and a personal computer,
the Control and Configuration Software must also be used. Refer to instruction
manual D2-3348 for more information about the CS3000 Software.
The Regulator boards have one set of RS-232 transmit/receive lines. These lines
can be accessed by only one device at a time: connector J8, the RS-232 terminals
(1-3) on the terminal strip, or an Operator Interface Module (OIM).
3.2.3 Selecting AC Input Line Branch Circuit Fuses
ATTENTION: Most codes require that upstream branch circuit
protection be provided to protect input power 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.
