With the assumption that the subject equipment falls under the 60950 series of Standards, then the following types of disconnect devices are permitted:
- the plug on the power supply cord; - a mains plug that is part of DIRECT PLUG-IN EQUIPMENT; - an appliance coupler; - isolating switches; - circuit breakers; - any equivalent device. Where a plug on the power supply cord is used as the disconnect device, the installation instructions shall state that: the socket-outlet shall be installed near the equipment and shall be easily accessible. The operating instructions, and the installation instructions for PLUGGABLE EQUIPMENT intended for USER installation, shall be made available to the USER.

( FCC class A in the US ) We noticed that the unit DOES NOT have a power switch or a mains disconnect. In order to turn the unit off you have to pull out the plug >from the unit or the wall. This units runs on 120V- 220V auto-range. Does this violate any safety rules in the US or Europe? The unit has an NRTL mark on it but is seems a little bizarre that it does not have a way of disconnecting power other than pulling out the plug. Anyone have any clarification on this......
