2.1.2.2 Power Input
The installation of a 3600 instrument should only be performed by personnel
specialized and authorized to work on electrical installations, in accordance with
relevant European and/or national regulations.
In accordance with safety standard EN 61010-1, it must be possible to disconnect
the power supply of a 3600 instrument in its immediate vicinity.
While the instrument’s electronics are well shielded, it is still advisable to locate
the instrument as far as possible from any source of electromagnetic perturbation.
AC Power Input
AC power connections for wall mount instruments use the rightmost waterproof
cable gland, and are wired according to a label inside the cabinet.
For wall mount instruments, a flexible cable of the recommended type H05VV-F 3
X 0.75 mm

should be used. The length of the cable should be three meters
maximum and it should have a separable plug (with three connectors, L+N+PE),
without a locking device, to mate with a socket outlet in the building. The cable
and the plug must conform to an appropriate European or national standard.
Three “FAST ON” 6.3-mm red, spade-type connectors are supplied with the wall
mount instrument for wires measuring from 0.5–1 mm

.
1. Remove the exterior insulation of the cable for a length of about 50 mm.
2. Insert the cable through the rightmost cable gland.
3. Strip the wires for a length of about 8 mm.
4. Put a “FAST ON” (spade-type) connector on each of the 3 wires.
5. Put the live, neutral, and earth wires on the corresponding spade plugs of the
mains filter, as indicated on the label affixed to the bottom of the wall mount
box, opposite the filter.
6. Slide the cable farther through its cable gland until its external insulation
penetrates about 6 mm inside the measurement box, blocking the cable gland.
