1. Determine the desired form of fixing (open/covered meter mounting or
extended suspension hook for 230 mm suspension triangle height). If
holes for a suspension triangle height of 230 mm are already present,
use the optional extended suspension hook depicted below. This
hook can be ordered with the part number 74 109 0072 0 (minimum
order quantity 50) from:

suspension triangle height
2. Either set the meter suspension hook in the relevant position as shown
below or replace the suspension hook with the extended hook by lifting
the latch slightly and pulling out the shorter hook. Insert the extended
hook into the grooves in the same way the shorter hook was inserted
(bent towards rear) and push it down until it clicks into place.

3. Check with a phase tester or universal measuring instrument whether
the connecting wires are live. If so, remove the corresponding supply
fuses and keep them in a safe place until installation is completed, so
that they cannot be replaced by anyone unnoticed. Open the voltage
connections at the test terminal block with an insulated screwdriver
and check whether the short-circuit jumpers of the circuit are closed.
4. In case there are no holes provided, e.g. as in the case with the 230
mm suspension triangle: Mark the three fixing points (suspension
triangle as in following illustration) on the mounting surface provided:
– horizontal base of suspension triangle = 150 mm
– height of suspension triangle for open mounting = 206 mm
– height of suspension triangle for covered mounting = 190 mm
