IMPORTANT: The 48/50MP units generate, use, and can radiate radio frequency energy. If units are not in- stalled and used in accordance with these instructions, they may cause radio interference. They have been tested and found to comply with limits of a Class A com- puting device as de®ned by FCC (Federal Communi- cations Commission) regulations, Subpart J of Part 15, which are designed to provide reasonable protection against such interference when operated in a commer- cial environment.

POWER SUPPLY Ð Electrical characteristics of available power supply must agree with unit nameplate rating. Supply voltage must be within the limits shown in Table 5.

Field Wire Routing Ð Field wiring is brought into the unit through the bottom of the control box.

A 35¤8-in. hole for ®eld power wiring and a 7¤8-in. hole for

24-v control wiring are provided in the bottom of the control box. Field-supplied couplings must be used when routing wir- ing into the control box.

POWER WIRING Ð Units are factory wired for 460-v as shown on the unit nameplate. The main terminal block is suitable for use with aluminum or copper wires. Maximum wire size is 500 MCM.

Branch circuit for power supply to unit must be protected against ground fault or short circuit. Provide an overcurrent protection device in the branch circuit. The MOCP (Maxi- mum Overcurrent Protection) value for this device is shown on unit informative data plate.

When installing units, provide and install a unit safety dis- connect per NEC of adequate size. Refer to Electrical Data tables for disconnect sizing. Disconnect may incorporate branch circuit fusing (if local or national codes permit) but combi- nation disconnect fuse is not required. Disconnect must be able to be locked OFF.
