Overvoltage protection
The RESOL overvoltage protection device SP1 should be used in order to protect the
susceptible temperature sensors in or at the collector against induced overvoltages.
In the case of local thunderstorms, voltage peaks which could destroy the sensor can be
induced in the sensor cable. The protector diodes in the SP1 limit these overvoltages
to a value harmless to the sensor.
The best way to protect the sensor is to install this connecting box close to the sensor.
Because of the weather conditions, the SP1 is designed as a robust connecting box in a
dripping water-protected housing which can be used outdoors. Seven rubber glands for
the sensor cables in the side walls of the connecting box allow for an easy installation
in each position.

Safety advice
Please pay attention to the
following safety advice in order
to avoid danger and damage to
people and property.
Please pay attention to appro-
priate usage of the product (see
pages 1 and 2). Improper use
excludes all liability claims.
The device is to be operated
on safety extra-low voltage
(SELV).
Attention should be paid to:
- valid local regulations
- the statutory provisions for
prevention of industrial acci-
dents,
- the statutory provisions for
environmental protection,
- the Health and Safety atWork
Act 1974
- Part P of the Building Regula-
tions 2005
- BS7671 Requirements for
electrical installations and rele-
vant safety regulations of DIN,
EN,TRGI,TRF and VDE.
Suitably qualified personnel
should carry out installation and
maintenance.

1. Mounting After the screws have been loosened (1), the upper part of
the housing can be removed from the connecting box. With
the aid of the two holes (2) the lower part of the connecting
box has to be fastened to a plane and stable surface. The
protective caps (3) have to be removed from the bottom
and inserted into the screw holes.
2. Electrical connection Pierce the cable glands with a pointed object. Insert the
cables into the holes and pull them slightly back, such that
the rubber layer is slightly turned to the outside.Thus the
device is protected against moisture. Connect the sensor
cable to the terminals 1A and 1B, and the connecting box
cable to the terminals 2A and 2B. If polarity has to be con-
sidered (this is required for the irradiation sensor CS10!),
the cables with the same designation have to be connected
to the same designations (1A and 2A as well as 1B and 2B
are the two connection paths).
Sensor cables carry safety extra low voltage (SELV) and must
not be placed in a gland together with cables carrying 230 V.
If the connecting box is used outdoors, it is recommended
to pierce the condensation water hole at the bottom after
the device has been installed.
