6 Installation
CAUTION
During installation, the safety regulations in chapter 2 and the accident
prevention rules must be strictly observed!
The electronic timers have been manufactured in accordance with the
current EC directives.
Installation, start-up and maintenance may only be carried out by author-
ized qualified personnel.
For installation and operation of the electronic timers the regulations and
directions of the local engineering associations (e.g. VDE) and the known
accident prevention rules have to be observed.
6.1 Mounting the Electronic Timer
AP 117 electronic timers can be
mounted in any position.
The 4 bores (Ø 4.25 mm) for attach-
ment of the unit are accessible once
the cover has been opened.
Dimensions of the mounting bores:
108 mm × 127 mm (see Ch. 3 Tech-
nical Data).
The mounting surface must be even
and level, in order to avoid damaging
of the housing.
6.2 Electrical Connection
DANGER
ATTENTION:
The AP 117 must not be mounted or dismounted with voltage applied!
Electrical installation of the AP 117 electronic timer may only be per-
formed by authorized specialists.
The authorized specialists must work only with insulated tools which are
suitable for the application.
CAUTION
Only suitable and flexible supply cables should be used for the connec-
tion of the electronic timers AP 117. Cables and earthing conductors must
be connected according to the respective regulations.
The conductors in the supply cable for connection of the AP 117 to the power
supply must be temperature-resistant and have a sufficiently large cross-
section matching the used cable length.
DANGER
The electric lines must be carefully routed. It must be ensured that cables
cannot be worn through by vibrating components.
It should be checked that the electric lines and their connectors are in
perfect working condition at regular intervals (generally every six months).
Any faults which are discovered must be immediately remedied.
Protect cables from high temperatures, lubricants and sharp edges.
CAUTION
At delivery the fuse is located in the socket.
The operating voltage for the electronic timer is also the supply voltage for the
device to be controlled (solenoid valve, contactor, vibrator, motor, etc.).
