Controller requirements and specifications
Installation Planning Guide 5-3
The required wall outlet voltages for USA / Canada, United
Kingdom, and the rest of Europe are as follows:
• USA / Canada: The voltage at the wall outlet is 100 to 120
VAC between AC hot and neutral, and between AC hot and
GND. The voltage is less than three VAC between GND and
neutral.
• United Kingdom: The voltage at the wall receptacle is 200 to
240 VAC between live and neutral, and between live and
earth. The voltage is less than three VAC between earth and
neutral.
• Europe: The voltage at the wall receptacle is 200 to 240 VAC
between supply pins. The voltage between one supply pin
and earth is 200 to 240 VAC. The voltage between the other
supply pin and earth is less than 3 VAC.
Refer to the controller electrical requirements table earlier in this
chapter for a description of the power specifications for the
controller.
WARNING
To reduce the risk of electrical shock, do not plug
components into any other type of power system. Contact
your facilities manager or a qualified electrician if you are
not sure what type of power is supplied to your work area.
Environmental specifications
The controller is a sturdy piece of equipment; however, like any
piece of electronic equipment, it must be treated properly. Avoid
extremes in temperature and other environmental hazards.
Place the controller in a relatively dust-free area that is well-
ventilated to avoid overheating.
In general, if your working environment is comfortable for you, it
is suitable for your controller. The following sections define the
acceptable environmental ranges for the two controller models
with which your system may be configured.
