The Exterior 50 & 100 PSU is fully auto-sensing and can be connected to
AC mains power as follows:
• The EU model PSU can be connected to mains power at 100-240 VAC
nominal at 50/60 Hz.
• The US model PSU can be connected to mains power at 100-240 VAC
nominal at 60 Hz.

Power cable and plug
Cable that meets the power cable specifications listed on page 9 in the
”Protection from electric shock” section must be used to connect the
Exterior 50 & 100 PSU to an AC mains power source and to interconnect
PSUs if you create a power cable link.
The cable used to supply the system with power must be either hard-wired
to a building’s electrical installation, providing an easily accessible power
on/off switch close to the PSU, or fitted with a suitable grounding-type
(earthed) power plug that matches the local power outlets.
If you fit a power plug, follow the plug manufacturer’s instructions and
locally applicable wiring color code. Table 2 shows some pin and wire
color code identification schemes.
