(2)

For the purposes of this paragraph, the requirements of Table 4 apply to multi-wattage separate control gears in respect of the maximum declared power on which they can operate.

(3)

Where a manufacturer or importer has declared in the technical documentation that a separate control gear has been designed for no-load mode, the no-load power Pno of the control gear must not exceed 0.5W.

(4)

The standby power Psb of a separate control gear must not exceed 0.5 W.

(5)

For a connected separate control gear—

(a)

the networked standby power Pnet must not exceed 0.5 W;

(b)

the allowable values for Psb and Pnet must not be added together.

(6)

This paragraph is subject to the exemptions in paragraph 3(3) of Schedule 4.
