Helpful Hint:
All earth ground
connections must be
continuous and
permanent.
Compumotor
recommends a single-
point grounding setup.
Proper grounding of electrical equipment is essential to ensure the safety of
personnel. You can reduce the effects of electrical noise due to
electromagnetic interference (EMI) by proper grounding. All Compumotor
equipment should be properly grounded. A good source of information on
grounding requirements is the
National Electrical Code
published by the
National Fire Protection Association of Boston, MA. In general, all
components and enclosures must be connected to earth ground through a
grounding electrode conductor to provide a low impedance path for ground
fault or noise-induced currents.
RP240 Connections
The RP240 operator panel is connected to the Extended X (SX, ZX, or Model
500) and 6000 Series (6200 or 6250) products by means of a four wire shielded
cable (user supplied). For cable lengths up to 50 feet long, Compumotor
recommends using 20 AWG wire. Cable lengths longer than 50 feet are not
recommended. This in accordance with the Electronic Industries
Association (EIA) recommendations for RS-232C at 9600 baud.
