Control Receivers.
2.2 SITE PREPARATION
2.2.1 Operating Environment Considerations.
The control receiver is designed to operate within a computer-oriented
environment. Maintain the environmental conditions as described in
paragraph 1.4.
2.2.2 Power and Grounding Requirements.
a. Power Requirements
The CRX-500 Series Control Receivers require either a 120 Vac or 220
Vac, 50/60 Hz, 180 Watts.
b. Grounding Requirements
The control receiver must be connected to a true earth ground. This is
very important for two reasons:
1. In the event of internal electrical faults, such as shorts, the entire
fault current is carried to ground. This protects operating
personnel from hazardous shock.
