Provide Suitable Panel Enclosure and Determine Locations for NGC-40-BRIDGE Assembly in Panel*
1. Provide suitable panel enclosure
The NGC-40-BRIDGE must be mounted in an enclosure to protect its electronic components. For indoor applications, use a minimum NEMA 1 enclosure (NEMA 12 recommended). For outdoor applications, use a NEMA 4 or NEMA 4X enclosure depending on the requirements.
Note: The Raychem NGC-40-BRIDGE is designed for operation in ambient temperatures from 40°C to 65°C (40°F to 149°F ). If the ambient temperature is outside this range, a space heater and/or cooling fan will be required in the panel.
2. Determine locations for the NGC-40-BRIDGE assembly in the electrical panel.
The NGC-40-BRIDGE should be located in the rear of the panel. The NGC-40-BRIDGE assembly is an electronic unit and must not be located where it will be exposed to strong magnetic fields or excessive vibration.
