Power Receptacle and Power Cord

4-4 Installation
Connect the female end of the VPU200 power cord to the power receptacle
located at the rear of the case (see Figure 4-1). To store the power cord when
it is not in use, wrap it around the L-shaped brackets located at the rear of
the case. Connect the male end of the VPU power cord to 110 VAC, 50 or 60
Hz power source (220 VAC if VPU has been converted as described above).
Plug the power cord into the same power source as the controller. In a noisy
environment, this is critical for proper performance of the VPU.
The wall receptacle for VPU power must accommodate the three-pronged male
connector. The receptacle must have three contacts, as shown in Figure 4-2,
including one for safety earth ground. If a three-contact receptacle is not used,
damage to the terminal and/or personal injury can occur. If an extension cord is
needed, it must be a three-wire type.
For 220-volt operation, the power cord used must be capable of carrying three
amperes, and its male connector must be compatible with local power outlets.
