Any terminals or wiring connected to the input or output, which are accessible in normal
operation, must only be connected to signals complying with the requirements for Safety
Extra Low voltage (SELV) circuits.
The mains supply to the instrument must be protected by an external 1-amp fuse and a
suitable switch or circuit breaker, which should be near the instrument.
Note: The instrument contains no user serviceable parts.
3 Installation
3.1 Installing the Instrument into a Panel
Make a cut-out in the donor panel 138.0 x 68.0mm (DIN 43700).
The maximum panel thickness is 8mm and, if an effective IP65 weatherproof seal is required,
the minimum recommended panel thickness is 1.6mm.
Pass the instrument case through the cut-out in the donor panel and attach the two retaining
screws to the studs on either side of the case.
Tighten the retaining screws onto the back of the donor panel until the instrument is clamped
securely in position. The screws must be tightened sufficiently to affect a seal between the
front of the donor panel and the back of the instrument bezel, but never over tightened.
3.2 Instrument Wiring
