(3) Environment
(a) Operate the servo amplifier at or above pollution degree 2 set forth in IEC/EN 60664-1. For this
purpose, install the servo amplifier in a control box which is protected against water, oil, carbon, dust,
dirt, etc. (IP54).

Note 1. Ambient temperature is the internal temperature of the control box.
2. The servo amplifier 200V 3.5kW or less and 100V 400W or less can be mounted
closely. In this case, keep the ambient temperature within 0 to 45
(32 to 113 ) or
use the servo amplifier with 75
or less of the effective load ratio.
(4) Power supply
(a) This servo amplifier can be supplied from star-connected supply with earthed neutral point of
overvoltage category
set forth in IEC/EN 60664-1. However, when using the neutral point of 400V
system for single phase supply, a reinforced insulating transformer is required in the power input
section.
(b) For the interface power supply, use a 24VDC power supply with reinforced insulation on I/O terminals.
(5) Grounding
(a) To prevent an electric shock, the protective earth (PE) terminal (marked
) of the servo amplifier must
be connected to the protective earth (PE) of the control box.
(b) Do not connect two ground cables to the same protective earth (PE) terminal. Always connect cables to
the terminals one-to-one.

PE terminals
(c) If an earth leakage circuit breaker is used, always earth the protective earth (PE) terminal of the servo
amplifier to prevent an electric shock.
