Connection types and ratings:
LAN connection - RJ45 on Cat5 or Cat5e UTP cable
•
All other connections - 0.14mm² to 2.5mm² (26 to 14awg) for rigid/solid cables,
•
0.14mm² to 1.5mm² (26 to 16awg) for flexible/stranded cable.
Refer to safety information in section 5.2
Output 1 - rating 2A at 250Vac, 2A at 30Vdc
Output 2 - 3A at 250Vac, 1A at 24Vdc
(Note: for Output 1, a continuous current of 2A will cause a 22° C temperature rise to the
PCB area close to the terminals after 10mins. If the current is below 1A this
temperature rise will be less than 5° C. Output 2 will not give any significant temperature
rise up to its rated current of 3A)
Power Connection - 48Vdc from external supply, connected via terminal block in rear
section. Note that the VoIP module itself requires only 100mA from the 48V supply –
the majority of the power is required by the induction loop amplifier fed by the 48-12V
DC-DC converter.
Control inputs - for connection to voltage free contacts only. Internal pull-up resistor
source current = 300uA. These inputs form part of a SELV circuit and precautions must
be taken to prevent hazardous voltages being applied to these circuits
Cleaning
6.
Recommended cleaning methods are outlined below:
Normal Cleaning
6.1.
For normal cleaning we recommend "Virosol", manufactured by Clover products.
Carefully follow manufacturer's instructions for storage, handling and use.
Stainless Steel Push-buttons
6.2.
Stainless steel push-buttons, where fitted, should be cleaned regularly especially if the
Help Point is in a marine environment. The stainless steel may show signs of
discolouration or rust – this will not damage the buttons or impair their performance but
may look unsightly and can be cleaned off using normal cleaning agents as above. In
extreme cases a mild abrasive may be necessary.
