5.4 Electrical Installation
IMPORTANT
• The metering pump must be electrically installed by authorised, “skilled” personnel
only.
• When installing the metering pump also observe the installation instructions for
devices in explosive areas; for Europe the European operator directive 99/92/EC
(ATEX137) and the ATEX Product Directive 94/9/EC (ATEX 95), implemented in Germany
by the new health and safety legislation!
• Observe the relevant standards e.g. DIN EN 60079, DIN EN 60079-11, DIN VDE and/or
0118 “Erecting electrical equipment in explosion-threatened areas” DIN EN 60079-14!
• Note all national directives which apply to the installation when installing outside
Germany.
• Intrinsically safe installations must be checked by persons with “recognised
qualifications“.
• Do not connect mains power supply to the external terminal (11).
• The internally used fusible link has a breaking capacity of 1,500A. If the short-circuit
current in the supply network ma be larger than 1,500A, the pump is to be protected
with a suitable back-up fuse with a higher breaking capacity (rated current smaller
than 1,500A).
Power connection Electrical data see 3.6
The connection terminal (23) for the equipotential bonding conductor is located on the housing
next to the power supply terminal (12).

* Internally insulated, connect to a free terminal on the outside.
** Twist the three single coaxial earth leads together, fit yellow/green sleeve and attach to the
earth lead terminal.
Induction voltage If the pump is connected to the power supply parallel to inductive loads (e.g. solenoid valve,
motor), it must be electrically isolated from these loads in order to avoid damage caused by
induction voltages when switching off.
왘 Use several contacts for power supply via auxiliary contactor or relay.
왘 In the 100-V- to 230-V-versions, connect a varistor (U
N
= 275 V) or RC-element
(0,22 uF/220 Ohm) in parallel.
Switching on With power switch (13), a power switch must be provided by the customer for the 500 V version.
