Paradyne KeepInTouch 3760 User Manual page 12

Power Requirements
It is a condition of approval that the power required by the host
and the total of all adapter cards installed within the host
environment, together with any auxiliary apparatus, does not
exceed the power specification as stated in the Technical
Reference Material of the host apparatus. The power
requirements for the KeepInTouch Card modem are 5V and
1 Watt.
In order to maintain the independent approval of this card, it is
essential that other optional cards do no use (or generate)
mains Voltages or any other hazardous voltage. A hazardous
voltage is one which exceeds 42.24V peak a.c. or 60V d.c. If
you have doubt, seek advice from a competent engineer before
installing other adapters into the hoist equipment.
The equipment must be installed such that with the exception of
the connections to the host, clearance and creepage distances
shown in Table 1 are maintained between the card and any
other assemblies which use or generate a voltage shown in the
table. The larger distance shown in brackets applies where the
local environment within the host is subject to conductive
pollution or dry non-conductive pollution which could become
conductive due to condensation. Failure to maintain these
minimum distances would invalidate the approval.
