2.The connection of the power cord should also be in accordance with Article 110.14 of ANSI/NEPA 70.

3.Using pin terminals (as shown in the Figure 14) for the power cord at the end connected to terminal strip is recommended.

"Warning - Risk of Electric Shock. Connect plug of outdoor power cord only to a covered Class A GFCI receptacle that has an enclosure that is weatherproof with the attachment plug cap inserted or removed."

4. If conduit is used, be sure to choose wires in accordance with the following criterion.

Wire Gauge	Wire Type	Tightening Torque	Minimum temperature
(AWG)		(lb-in)	rating of conductors
10-18 AWG	Copper conductors	7	75°C
Copper Conductors

Table 4: Conduit Wires

"Warning - Risk of Electric Shock. Install wires going through conduit only on a circuit protected by a Class A GFCI."

"Warning: Power supply cord must not be attached to the building surface, nor run through walls, ceilings, floors and similar openings in the building structure."

"Warning: The socket outlet shall be installed near the equipment and shall be easily accessible."

"Warning: To reduce the risk of fire, connect the unit only to a circuit provided with Listed 20 Amperes circuit breaker in accordance with the National Electrical Code, ANSI/NFPA."

Note: Wiring, liquid tight fittings, conduit and cable glands shall be selected in accordance with Article 300 of ANSI/NFPA 70.

Note: Before installing the unit, confirm that there is listed IEC 61643-12 or UL1449 low surge protective device with surge protection level less than 2.5KV being connected between the unit and the power source.

Note: Surge Arrestors or Transient Voltage Surge Suppressor external to the equipment to reduce overvoltages or to bypass surge current shall be installed per Article 280 or 285 of ANSI/NFPA 70.

Note: Be certain to keep coolant or oil away from the unit.
