2.3.2.2 Construction
2.3.2.2.1 Housing
The telephone type ExResistTel IP2 / IP154 has a non coloured housing made of an
electrostatic conductive pressed basic material and a stainless steel keypad.
Optionally the housing can be coloured with an electrostatic conductive colour.
In the front plate of the keypad is a display cut-out closed with a viewing glass.
The housing consists of a box-shaped bottom part with a tray for inserting the
electronic and a curved top cover with a keypad.
The top cover will be pressed with four screws to the upper part with in between a
revolving seal and generates the intrinsically safe as well as the non-intrinsically safe
terminal compartment. In the tray is a grouting cup with the embedded electronic.
2.3.2.2.2 Configuration Plug Connector
A 6 pin plug connector sticks out of the grouting tray inside the telephone (14) (see
Figure 12 on page 46).
The configuration plug connector will be used by the manufacturer of the telephone
type ExResistTel IP2 / IP154 for configuration only and must not be connected.
The programming by the installer is not allowed.
2.3.2.2.3 Intrinsically Safe Keypad Connection
An intrinsically safe 14-terminal ribbon cable (7) with a female plug will be carried
out of the grouting tray inside the telephone (see Figure 12 on page 46).
The female plug has to be plugged to the 14 pin plug connector (8) in the upper part
of the housing securely, before the telephone will be screwed down.
