Battery Connections
The X100 can be connected to two separate battery strings through the battery
two pairs of IMO ER35 terminal blocks. These terminals accept cables in the
range 10AWG to 2AWG. A minimum cable size of 4AWG is recommended when
employing only the internal 100A circuit breakers for protection (see section 8.2).
If a battery string is separately provided with a lower rated circuit breakers or fuse
then smaller gauge cables may be used as appropriate.

Alarm Relay and Battery Temperature Probe Connections – J2
Connection to the Form-C alarm relay outputs is made through the 18-way spring
clamp terminal connector. There are a total of 4 relay outputs with Normally Open,
Normally Closed and Common Contacts available for connection. The individual
relay contact sets are fully isolated and may be floated from GROUND by up to 100V.
Maximum contact current and voltage are 1A and 30V (DC or AC) respectively.
This connector accepts wire sizes from #28AWG to #10AWG.
The alarm relays are designated K1 to K4. K1 and K2 are pre-programmed for
MAJOR and MINOR alarm conditions by default. K3 and K4 are not programmed
for any alarm function by default and may be programmed using the
Alarm
Configuration
WEB page described later in section 12.
Connection of the supplied battery temperature probe, if required, is made using
terminals 1 and 2 of this same spring clamp terminal connector. An optional external
temperature probe may also be connected using terminals 3 and 4. Terminals 5 and
6 allow connection of a volt free contact closure input.
