Risk of electric shock. Removing the front cover will grant access to internal
circuits which may be at dangerous voltage. Disconnect the input signal and
the power supply to prevent electric shock to the operator. Operaon must be
performed by qualied personnel only.
Use a at screwdriver to unlock clips ‘D’, C’, ‘B’
and ‘A’, in this order. Remove the front lter.
Gently let the internal boards slide out of the
instrument.
To reinsert the boards in the housing :
1. make sure that the boards are correctly con-
nected to the displays pins
2. slide the boards into the housing guides
3. place the front lter at corner X, and then
insert clips ‘A’, ‘B’, ‘C’ and ‘D’ in this order. XA

10. Regulaons
This instrument conforms to the actual CE regulaons. For a copy of the ‘CE declaraon
of conformity’ see secon 3. Applicable regulaons are :
Security regulaons EN-61010-1 (‘Fixed’ equipment, ‘Permanently connected’.
‘Double’ isolaon. ‘CAT-II’ category)
Electromagnec compability regulaons EN-61326-1
According to direcve 2012/19/EU, electronic equipment must be re-
cycled in a selecve and controlled way at the end of its useful life.
This instrument does not provide a general mains switch and will start operaon as
son as power is connected. The instrument does not provide protecon fuse, and the
fuse must be added during installaon.
Risk of electrical shock. Instrument terminals can be connected to
dangerous voltage.
Instrument protected with double isolaon. No earth connecon
required.
Instrument conforms to CE rules and regulaons.
