Electrical Wiring
NOTE
All electrical connections should be made by a licensed electrician. All local and National
codes should be followed as applicable.
Circuit Requirements
The TWSD16128PHC should be connected to a 120V, 15A feeder circuit.
The maximum capacity of the power receptacle in the unit is 120V, 12A.
The circuit breaker of the feeder circuit is considered to be the disconnect device for
TWSD16128PHC. Therefore, this circuit breaker should be readily accessible.
The strain relief (liquid tight cord connector) is suitable for flexible cord with a diameter of
10mm. We recommend using S-W or S-J cord, minimum 16 AWG.
WARNING
– TO REDUCE THE RISK OF ELECTRIC SHOCK, DISCONNECT SUPPLY
MAINS BEFORE SERVICING.
The supply line used to feed power to the feeder circuit should be rated for outdoor use.
Refer to the NEC and local codes as applicable.
WARNING
: To prevent the risk of electric shock and equipment damage, disconnect any
and all power supply to the enclosure before installing, maintaining or trouble shooting this
product or any products inside the enclosure.
Electrical Connection
Before running electrical power to the device, you must first install the cord gland bushing
that comes included with the enclosure. Be sure the install the cord gland bushing with the
gasket of the outside of the enclosure. Also, the cord gland bushing nut should be tightened
snugly by hand. Once the bushing has been tightened by hand then use a wrench to apply
an additional quarter turn for final tightening. Do not over tighten the nut – over tightening the
nut can result in the cracking of the cord gland bushing. Refer to figure 8.
The electrical wiring should be routed through the cord gland bushing to the terminal block.
Refer to wiring diagram – figure 5.
