WARNING Mains voltages are present in this instrument when power is connected.
AC Powered Units (input board 24680501)
The Hydrastep 2468C must be installed with a fuse or circuit breaker with a maximum rating of 5A mounted as close as practicable, in an easily reached location. The fuse or circuit breaker must be uniquely identified as the disconnecting device.
The cable gland used must have an inlet or bushing with a smoothly rounded
A shielded power cable, and shielded signal cables with the connection to the unit through RF glands mounted on the gland plate should be used for all units that need to comply with the requirements of the European EMC Directive.
Gain access to each input board and proceed as follows:
1.Ensure that the mains cable is safely isolated before starting work, and ensure that enough length is prepared to install it according to the route described in Step 2 and Step 3 below. The power inlet must be dedicated to that function only. No signal wiring must share the power inlet cable. Two separate protected AC mains circuits (of the same electrical phase) may be provided in a suitably rated
2.Use a good quality RF cable gland, and ensure there is a good annular (ring shape) connection with the screen. A ferrite (supplied) must be attached inside the unit to each supply input, as close to the inlet gland as possible. Make a
