2-7.3. Connecting the Power Equipment
Proceed as follows:
• External Mains
o Connect Mains power to the Mains Circuit Control Box (MCC)
o Wire one 0.4" (10mm) ground cable from the Mains ground
connection to the MCC.
• Uninterruptible Power Supply (UPS)
o Connect the MCC to the UPS.
• If any doubt concerning grounding arises, ask for a ground test performed by a
qualified electrician.
2-7.4. Grounding
Proper system grounding is an extremely important part of the system installation. As with the AC
power, the grounds for all system components should return to the same circuit breaker panel. This
helps you to assure a common ground throughout the system, which is necessary for protection of
the RS-485 data loop circuitry. Ground for all system devices should be wired to the breaker panel
ground bus bar, which in turn should be grounded to a ground rod. A conduit ground does not
provide sufficient ground. It is recommended that the neutral and ground bus bars be bonded
together when it is not prohibited by local codes.
