(2) Installation
Install a fan of 100CFM (2.8m
3
/min) air flow 4[in] (10.16[cm]) above the servo amplifier (drive unit) or
provide cooling of at least equivalent capability to ensure that the ambient temperature conforms to the
environment conditions (55
or less).
(3) Short circuit rating: SCCR (Short Circuit Current Rating)
This servo amplifier (drive unit) conforms to the circuit whose peak current is limited to 100kA or less,
500Volts Maximum. Having been subjected to the short-circuit tests of the UL in the alternating-current
circuit, the servo amplifier (drive unit) conforms to the above circuit.
