2.2 Power Supply
A wide range power supply is standard. The nominal operating range is 48-250
Vdc, 100-240 Vac, +/-10%, 50/60 Hz. To protect against a possible short cir-
cuit in the supply use an inline fuse or circuit breaker with a 5 A rating. Make
the chassis ground connection to ensure proper operation and safety.
There are no power switches on the recorder. When the power supply is con-
nected, the recorder starts its initialization process. See “Installing TESLA
Control Panel” on page 3-1 for the start up process details.
The use of an external surge protection device is required to pass the surge im-
munity requirements of IEC/EN 60255-22-5 Criterion A. ERLPhase recom-
mends either of the following for this function:

er’s grounding terminal to the station ground. Do not rely on the rack
